Quick Bibliography Series Bibliographies in the Quick Bibliography Series of the
National Agricultural Library, are intended primarily for
current awareness, and as the title of the series implies, are
not indepth exhaustive bibliographies on any given subject.
However, the citations are a substantial resource for recent
investigations on a given topic. They also serve the purpose
of bringing the literature of agriculture to the interested
user who, in many cases, could not access it by any other
means. The bibliographies are derived from computerized on-
line searches of the AGRICOLA data base. Timeliness of topic
and evidence of extensive interest are the selection criteria.
The author/searcher determines the purpose, length, and search
strategy of the Quick Bibliography. Information regarding
these is available upon request from the author/searcher.
Copies of this bibliography may be made or used for
distribution without prior approval. The inclusion or
omission of a particular publication or citation may not be
construed as endorsement or disapproval.

Abstract: Chisel tillage and furrow dikes (small earthen dams
constructed in the furrow) are commonly used to increase
infiltration and soil water storage in semiarid regions. Data
quantifying the combined influences of these practices are
limited. Our objective was to determine the effects of chisel
tillage, furrow dikes (with and without ponding), and drop
impact or surface crusts on infiltration. Infiltration rate
(IR) and cumulative infiltration (CI) into an Olton day loam
(fine, mixed, thermic Aridic Paleustoll) were measured by
applying water at 65 and 80 mm h-1 for 1 h using a rotating-
disk-type rainfall simulator. Furrow dikes increased
infiltration under both ponded and nonponded conditions.
Cumulative infiltration was higher when raindrop impact energy
was dissipated and, to some extent, when crusts were removed.
Infiltration rate at the end of water application was lower
with raindrop impact than when raindrop impact was eliminated;
however, there were no differences in the final IR between the
initially crusted and uncrusted soils. There were no
differences in infiltration between chisel-disk and disk
tillage measured during the mid growing season. Furrow dikes
not only detain water on the surface to provide more time for
infiltration, but also increase infiltration through increased
hydraulic head and additional tillage performed during dike
installation or by moving loose soil from the furrow into the
dikes. Our data do not support using the same hydraulic-
conductivity value for both diked and undiked field
conditions, which may cause underestimation of conservation in
furrow-diked fields.

Abstract: Extract: Cropland in minimum tillage rose from 15.8
percent of all cropland in 1973 to 29.1 percent in 1981. The
share for no-till rose from 2.0 to 2.9 percent during the same
period. These conservation tillage systems--minimum tillage
and no-till--can also reduce soil loss up to 99 percent over
conventional tillage. This report looks at trends in the use
of various tillage systems and compares their economic impacts
and effects on soil and water conservation, crop yields, and
pesticide and energy use, using selected results from studies
of tillage systems.

Abstract: Experimental designs of 14 subsurface drainage-
water quality studies conducted over the past 18 years are
reviewed. To more accurately determine mass contaminant flux
and processes, more intense monitoring of drain discharge rate
and drainage water quality is needed than in most past
studies. A recently installed field scale system of subsurface
drainage-water quality plots and associated equipment, capable
of intense, year round monitoring, is described and
preliminary data showing performance of the system is
presented. The material presented should be of interest to
those planning and designing drainage-water quality studies,
or refitting existing drainage installation for water quality
investigations.

analysis; Costs
Abstract: Data on harvest volumes, topography, and other site
and area characteristics were obtained from 22 timber harvests
in Alabama, Florida, and Georgia. An economic analysis was
then used to estimate the marginal costs of implementing each
state's recommended Best Management Practices (BMPs), as well
as a set of enhanced BMPs an these sites. Considering all of
the areas combined, the costs of using the recommended BMPs
averaged 2.9% of gross timber sale revenue, $2.34 per thousand
board feet (mbf) of timber harvested, or $12.45/ac. The cost
of implementing the enhanced BMPs averaged 5.1% of gross
stumpage value, $4.13/mbf, or $21.94/ac. Seed, fertilizer, and
mulch, broad based dips, and water bars were the most
expensive practices on a total cost basis. Culvert
installation, streamside management zones, and road relocation
costs were less expensive for most tracts.

Abstract: Phosphorus loading in surface water bodies due to
runoff from cropland is a major concern with respect to water
quality. Losses of water, soil, and different forms of P, from
five runoff plots treated with polyvinyl alcohol (PVA), were
compared to losses from five untreated plots. The plots were
on a loam soil with 6.5 to 9.5% slopes. The effect of a single
application of PVA was observed over 2 yr under natural
rainfall. During the first year after application of PVA,
runoff and soil losses were reduced by 56 and 80%
respectively. Extractable P, total P, and dissolved molybdate-
reactive P (DMRP) losses were reduced by 79, 75, and 64%,
respectively. Corn (Zea mays L.) grain yield on the treated
plots was 12% higher than on the control plots. All the above
differences were statistically significant. During the second
year, in which no tillage occurred and no PVA was applied,
total P and DMRP losses were reduced by 42 and 40%,
respectively, by the PVA treatment of the previous year.
Although runoff and soil loss were lower for the treated
plots, these differences were not significant at P = 0.05 (P
values were 0.11 and 0.10, respectively).

Abstract: High variability of atrazine
(2-chloro-4-ethylamino-6-isopropylamino-1,3,5 triazine)
residues in soil and shallow groundwater have been reported
under various agricultural management systems. This 2-yr study
was conducted to evaluate atrazine residue levels in soil as
influenced by no-till (NT) vs. conventional-till (CT) under
natural rainfall conditions. Atrazine was applied annually (at
1.34 kg/ha), 1 d after corn (Zea mays L.) planting, to two NT
and two CT plots. Atrazine residues within the 0- to 10-cm
soil depth of CT plots were higher than in the NT plots,
regardless of the difference in the rainfall patterns. Higher
(ca. 61%) mean atrazine residues in the CT plots over NT plots
in 1988 was most likely related to the rainfall that began 12
h after application. In contrast, in 1987, it rained 3 to 4 d
after application and the residues in the CT were only 31%
higher than in NT. These results indicate that even a subtle
difference in rainfall distribution (temporal) can result in
marked spatial variability in the distribution of atrazine.

Abstract: Water samples collected in the Mermentau River
Basin over several years at Louisiana Department of
Environmental Quality monitoring sites contained high levels
of total solids and nutrients during the spring that were
highly correlated to pre- and post-plant discharges from rice
fields. This study was developed to evaluate the potential of
selected management practices (MP's) for reducing total
solids, nutrients and pesticides from discharge water in order
to improve the surface water quality in southwest Louisiana.
Five rice plots located on the Rice Research Station in
Crowley, LA represented the different MP's to be evaluated.
The five water seeding MP's were: a.1-no till; a.2-water
cultivation with 30-day settling, a.3-dry cultivation with
clear water planting; a.4-mudding-in with vegetated filter,
and b-mudding-in (control). Quality of discharged water from
rice fields in the Mermentau River Basin was clearly affected
by the different MP's. From the first year of data, all the
MPa's were better than the mudding-in (MPb). The
concentrations of the total solids (kg/ha) in the discharged
water (initial + final drain) for the different MP's were in
the order: MPb(4860) > MPa.3(3906) > MPa.4(3412) > MPa.2(3068)
> MPa.1(1807). The Mpa.3, Mpa.4 and MPb had no detectable
amounts of pesticides being released. The 30-day holding
period (Mpa.2), clear water planting (MPa.3) and the mudding-
in with vegetated filter (MPa.4) were similar as far as TDS,
TSS and TS with the no-till (MPa.1) being the least. The 30-
day holding period (Mpa.2) and the no-till (MPa.1) had less
nutrients, but more pesticides released. Depending on the
priority of the stream problems, different MP's may be more
advantageous than others. All of the selected MP's were better
than the control (MPb), and therefore, should help to improve
water quality.

Abstract: Simulated rainfall was used on experimental field
plots to compare the effect of chemical fertilizer and sludge
application on sediment, nitrogen, and phosphorus in runoff
from no-till and conventional tillage systems. Chemical
fertilizer application under the no-till system resulted in
the least amount of total N and P in surface runoff. However,
sludge application under the no-till system resulted in the
least amount of NO3-N and sediment in surface runoff. The
worst water quality scenarios were observed when either sludge
or chemical fertilizer were surface-applied under a
conventional tillage system. Nitrogen losses from the
conventional tillage system were minimized when sludge was
incorporated into the soil. However, phosphorus and sediment
yield from such a system were significantly higher when
compared to phosphorus and sediment yield from the no-till
system. The results from this study indicate that the use of
sludge on agricultural land under a no-till system can be a
viable alternative to chemical fertilizer for nitrogen and
phosphorus control in runoff. A more cautious approach is
recommended when the sludge is incorporated into the soil in a
conventional tillage system because of potential for high
sediment and phosphorus yield in surface runoff.

Abstract: Economic and physical simulation models were
utilized to evaluate the effect of alternative soil and
agricultural chemical management systems, implemented under
the Conservation Reserve and Conservation Compliance Programs,
on pesticides' leaching, and returns to fixed farm resources.
Findings of the study show that the selection of appropriate
soil and chemical systems may not only increase farm returns
but may also result in a significant reduction in leaching and
hence ground water degradation.

Abstract: High soil selenium (Se) levels have been found in
association with uranium deposits in Texas. A concern that
high Se concentrations may be found in forages grown on
reclaimed mine lands prompted this investigation. A native
soil sampled near the mining area, and overburden materials
sampled from two Se enriched uranium mine soil sites were
compared in a plant growth study in the greenhouse. Shoot
yields and shoot Se concentration in each of ten grasses
common to the region were determined from plants harvested
three weeks after germination and from shoot regrowth
harvested four weeks after the first harvest. Shoot weights
were reduced for 5 of the 10 species growing in soils with
medium and high Se status. Total shoot weights of Cynodon
dactylon and Panicum coloratum from two harvests were
consistently highest in all soil materials and are highly
recommended for use as a stabilizing cover crop for lands
disturbed from uranium mining. Generally, no correlation was
observed between shoot weight and plant Se concentration or
uptake in the 10 species. However, plant tissue Se
concentrations in all species for at least one of the two
harvest dates were above the 5 mg kg-1 concentration
considered potentially harmful to grazing livestock.
Therefore, none of these species would be a suitable forage
for livestock grazing on reclaimed Se-enriched uranium mining
overburden.

Abstract: Since the mid-1930s a variety of soil conservation
practices have been applied to agricultural lands throughout
the United States. While intended to reduce soil erosion, if
effective, these practices should alter the hydrology of
streams which drain the treated lands. This hypothesis was
explored for the East Branch of the Pecatonica River, a gaged
221 square mile agricultural catchment in southwestern
Wisconsin. On the basis of the analysis of peak and daily flow
data there has been a decrease in flood peaks and in
winter/spring flood volumes and an increase in hydrologic rise
times and in the contribution of winter/spring snowmelt events
to base flow. These changes do not appear to be due to
climatic variations, reservoir construction, or major land use
changes. Instead, they appear to have resulted from the
adoption of various soil conservation practices, particularly
those involving the treatment of gullies and the adoption of
conservation tillage.

Abstract: A three-year field study was initiated in 1986 to
determine the impact of tillage practice, mode of pesticide
application, and pesticide formulation on chemical transport.
The 1.28-ha field site was divided into four plots, two each
devoted to no-till and conventional tillage management.
Pesticide transport was evaluated by monitoring the rate of
change in concentrations of pesticides in a shallow perched
water table, located approximately 1 m below the soil surface.
Pesticides monitored included atrazine, alachlor, cyanazine
and carbofuran. All three herbicides were applied as a single
broadcast spray: granular insecticide carbofuran was band-
injected at planting.

Abstract: Previous research has established that macropores
can rapidly transmit water through soil. This observation has
raised concern that macropores may also promote rapid movement
of agricultural chemicals to groundwater. This is a particular
concern for no-till fields where lack of disruption by tillage
can lead to the development of extensive macropore systems. In
order to investigate the effect of initial rainfall on
chemical transport, strontium bromide hexahydrate (SrBr2.6H2O)
and atrazine (2-chloro-4-ethylamino-6-isopropylamino-s-
triazine) were surface-applied to six 30 by 30 by 30 cm blocks
of undisturbed soil obtained from a 25-yr-old, no-till corn
(Zea mays L.) field with evidence of well-defined macropores
attributable to earthworm activity. Half of the blocks then
received a 1-h 5-mm simulated rain, which did not produce
percolate. Two days later, the blocks received a 0.5-h 30-mm
simulated rain, followed by another 0.5-h 30-mm rain 1 wk
later. The remaining blocks received only the two 30-mm
events. An average of 12% of the applied water passed through
all the blocks during and shortly after the first 30-mm rain.
Bromide, Sr, and atrazine losses in this percolate were 7, 10,
and 2 times less, respectively, from blocks that received the
5-mm rain than from blocks not receiving this initial, light
rain. The second 30-mm rain on the blocks not receiving the
initial 5 mm produced 1.6 X more percolate than the first 30-
mm rain. Yet, transport and flow-weighted average
concentrations of Br, Sr, and atrazine were all reduced. These
results indicated that the first storm after application can
move solutes into the soil matrix, thereby reducing the
potential for transport in macropores during subsequent
rainfall events.

Abstract: The fate of agrochemicals is often greatly affected
by the surface-soil conditions in the field. This study was
conducted to characterize the impact of two contrasting
tillage systems on the movement of agrochemicals in soil. The
two tillage systems were plow-tillage (PT) and no-tillage (NT)
for corn (Zea mays L.) production. The study included
incubation and leaching of undisturbed soil columns and
disturbed soil samples from 16-yr plots subject to the two
tillage regimes. The agrochemicals used in the study were
NH4NO3, atrazine (2-chloro-4-ethylamino-6-
isopropylamino-1,3,5-triazine-2,4 diamine), carbofuran (2,3-
dihydro-2,2-dimethyl-7-benzofuranyl methylcarbamate), diazinon
(0,0-diethyl-O-(6-methyl-
2(1-methethyl)-4-pyramidinyl phosphor- othioate), and
metolachlor (2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-
metoxy-1-methylethyl) acetamide). The results of this study
show greater ponded flow movement of all agrochemicals in
soils under PT vs. NT conditions. Strong evidence was found
for preferential flow through the soil, with the chemicals by-
passing much of the soil-matrix under recently plowed soils as
well as NT soils. Nitrate leaching was significantly greater
under PT than NT, apparently due to greater mineralizing
activity of the PT soil compared with the NT soil. The
pesticide movement also tended to be greater under PT than NT.
Caution should be exercised in generalizing to field
conditions, but these data suggest that there can be greater
leaching losses of surface-applied agrochemicals to
groundwater under PT than under NT.

Abstract: Extract: The CREAMS (Chemicals, runoff, and Erosion
from Agricultural Management Systems) model was used to
evaluate soil and nutrient losses for typical field situations
in Lancaster County, Pennsylvania. A wide range of field
scenarios was modeled as part of the economic evaluation of
the RCWP (Rural Clean Water Program) project. Best management
practices (BMOs) reduced surface losses of nutrients. Reducing
the amount of nitrogen applied to the field was the only
effective method for reducing percolate losses of nitrates.
Stored manure provides more plant-available nitrogen than does
daily-spread manure.

Abstract: Long-term assessment of solute transport in the
unsaturated zone is an important consideration for irrigation
management, pesticide management, and subsurface contaminant
restoration analysis and design. Mathematical models are often
used to perform such analyses. Modeling fluid flow and solute
transport in the unsaturated zone typically requires solution
of the nonlinear Richards equation and an advective-dispersive
equation for contaminant transport as a function of time. Such
solutions are possible but computationally expensive. A
simplified water balance approach to solve fluid flow in
shallow, drained unsaturated zones has been developed and
refined over the last 15 years. The objectives of this study
were to use results from a water balance model to obtain
solutions for solute transport in drained, shallow water table
soils, and to compare the results with solutions based upon
Richards' equation. Transient soil water flux rates computed
with a water balance model were used as input to a Petrov-
Galerkin advective-dispersive transport model to simulate
solute transport in unsaturated soils. The transport model was
checked for consistency by comparison with an analytical
solution. Sample simulations showed good agreement between a
Richards' equation-based transport model and a water balance-
based transport model. Simulations were performed to show
predicted trends in water quality over 1-year periods.

Abstract: Conceptual weaknesses in the use of costs of
average abatement as a measure of the cost effectiveness of
agricultural nonpoint pollution control are examined. A
probabilistic alternative is developed. The focus is on
methods for evaluating whole-farm pollution control plans
rather than individual practices. As a consequence, the
analysis is presented in a chance-constrained activity
analysis framework because activity analysis procedures are a
practical and well developed device for screening farm plans.
Reliability of control is shown to be as important as
reduction targets in designing farm plans for pollution
control. Furthermore, broad-axe prescriptions of technology in
the form of Best Management Practices may perform poorly with
respect to cost effectiveness.

Abstract: The ability of the CREAMS model to predict loadings
of runoff, sediment and nutrients from a New Zealand grazed
pasture was evaluated. Before use, CREAMS was adapted to
better represent N and P cycling in grazed pastures and the
seasonal variation in hydraulic conductivity observed at the
site. There was a moderately strong relationship (r2 = 0.81)
between daily surface runoff volumes predicted by this
modified model and volumes measured at the site for 62 events
over a three and one half year period. Although the ability of
the model to predict daily losses of sediment and nutrients
was considerably less (r2 < 0.45), the model was always an
unbiased predictor. This unbiased predictive ability provides
good estimates of losses over longer time scales (e.g.,
seasonal) which is often sufficient when evaluating the
impacts of land use practices on water quality. The adapted
CREAMS model successfully simulated measured reductions in
edge-of-field losses of sediment and nutrient upon
installation of a vegetated filter strip. We conclude that
although CREAMS has limitations in representing the dynamics
of grazed pastures, it shows potential as a water quality
management tool in pastoral watersheds.

Abstract: The relative importance of preferential pesticide
transport in agricultural soils was determined in a two-phase
study conducted on a silt loam soil in Maryland. The first
phase (1984) consisted of evaluating persistence and mobility
of atrazine
[2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine] and
cyanazine [2-chloro-4-(l-cyano-l-methylethylarnino)-6-
ethylamino-s-triazine] under no-tillage corn management. The
second phase (1986) dealt with persistence and mobility of the
same herbicides on fallow tilled soil subjected to frequent,
large water inputs. Although preferential flow was observed
under both treatments and water regimes, the no-till system
had the most rapid movement of herbicide relative to water
inputs. Additionally, all treatments indicated that the
greatest potential movement of surface-applied pesticide
occurred with the first water input subsequent to application.
Once the pesticide has been preferentially transported, it
appears to diffuse into the soil matrix, where it is no longer
subject to significant preferential movement. Based on field
data and calculated mass balance, persistence of atrazine and
cyanazine was unaffected by tillage practice and water regime.

Abstract: Monolithic soil cores were used to evaluate the
impact of tillage and point-of-chemical placement on off-site
movement of metolachlor. Nine 254-mm diameter soil cores were
removed from an agriculturally productive field site and
positioned under a rainfall simulator. Provisions were made
for collecting surface runoff and deep seepage from the cores.
A one-time application of metolachlor at a rate of 2.2 kg
active ingredient per ha was made to three bare, tilled
surfaces, three untilled surfaces beneath a covering of wheat
straw, and three untilled surfaces over-the-top of a covering
of wheat straw. The nine cores were subjected to simulated
rainfall events of 26.5 mm per hr intensity at 4, 48, 168,
504, 1008, and 2016 hours after application of metolachlor. A
small quantity of metolachlor exited the cores in both runoff
and in deep seepage water. There were no significant
differences in concentrations of metolachlor in deep seepage
among cores with the three different surface treatments. There
was, however, significantly more metolachlor in runoff from
cores where the chemical was applied over-the-top of wheat
straw. Results, thus, indicate that a contribution to improved
water quality may be made by developing under-residue
herbicide application practices.

Abstract: Agricultural source pollution of water resources
has been a source of concern in recent years. Research is
needed to define mechanisms of chemical and sediment loss in
runoff from agricultural land, and to develop management
practices that minimize transport of these pollutants. This
study was designed to compare the effect of no-till (NT) and
conventional chisel-till (CT) soil management on runoff water
volumes, sediment loss, and N and P loss from small watersheds
on a clay soil. Three NT and three CT watersheds located on
Houston Black clay vertisol soil (fine, montmorillonitic,
thermic, Udic Pellusterts) in east central Texas were used for
the study. Wheat (Triticum aestivum L.), corn (Zea mays L.)
and sorghum [Sorghum bicolor (L.) Moench] were grown
rotationally on the watersheds from 1984 to 1989. Runoff
amounts, sediment loss, and N and P losses were measured for
each rainfall event that produced runoff. Runoff volume was
not changed by tillage system and sediment loss and N and P
losses in runoff were less, on average, from NT than from CT.
Runoff averaged 1.3 ML ha-1 annually for both CT and NT.
Average annual quantities for sediment and nutrient losses
were: 160 kg ha-1 and 1575 kg ha-1 for sediment, 3.8 kg ha-1
and 8.1 kg ha-1 for N, and 0.8 kg ha-1 and 1.5 kg ha-1 for P
for NT and CT, respectively. These results indicate that the
loss of sediment and nutrients from agricultural lands could
be minimized by using NT on clay soils.

nonirrigated and irrigated dark brown Chernozemic (Typic
Haploborolls) clay loam soil. On both the nonirrigated and
irrigated soil, the effects from manure, applied annually at
greater than recommended rates for 11 yr, were minimal on Cu
and NH4 content and substantial on other parameters
determined. There were no significant effects due to tillage
methods on these soil parameters. The effects on these soil
parameters extended to greater depths under irrigation than
under nonirrigation. Most of the applied NH4 was nitrified,
volatilized, or fixed. The accumulation of organic matter,
total N, NO3, total P, available P, soluble Na, Ca+Mg, Cl,
SO4, HCO3, and Zn in the soil increased with increasing rates
of manure applied. The electrical conductivity and sodium
adsorption ratio of the soil increased and the soil pH in the
surface 60 cm of nonirrigated and 90 cm of irrigated decreased
with increased manure rates. The total NO3 accumulation in the
150-cm soil depth was near 1 Mg ha-1, even at recommended
rates, and was high enough to potentially cause soil and water
pollution. The available P accumulated mostly in the surface
soil and might be sufficient to interfere with the nutrient
balance of some crops. Long-term annual application of cattle
manure to southern Alberta soils at maximum recommended rates
[30 mg ha-1 and 60 Mg ha-1 (wet wt.) for nonirrigated and
irrigated land, respectively] is not advisable.

Abstract: Management of surface water has four broad
objectives: (1) Appropriate removal of excess water during wet
periods, (2) Water conservation for crop use, (3) On-site
erosion control to protect long-term soil productivity and
reduce short term damages, and (4) Off-site damage prevention
from sedimentation and water pollution. The various techniques
of water management vary in effectiveness for the four
objectives given. However, for production of crops on erodible
land the importance of water conservation to enhance yield and
potential profits must be emphasized. The benefits of water
management for on-site erosion control are well established.
Economic studies, however, conclude that structural approaches
to control on-site erosion are seldom profitable in terms of
protecting soil productivity. The use of a tillage and
cropping system designed for erosion protection is
economically more attractive than structures, especially if
the cropping system does not greatly reduce the total value of
farm products sold. In contrast to the on site losses annual
costs of off-site damages from cropland erosion and runoff are
probably 10 to 55 times as great. Grain crop production on
highly erodible land continues to be difficult and risky.
Whether farmers can achieve this profitably, and with
conservation compliance as defined by the 1985 Food Security
Act, will greatly depend upon the alternative types of land
available and the extent of conservation treatment required.

Abstract: Extract: The public cost of reducing erosion in a
west Tennessee watershed pilot program was 34 percent lower
than the national average. The difference was attributed to
the pilot program's emphasis on targeting specific erosion
problems and to the establishment of permanent vegetative
cover on highly eroding land. Even greater use of permanent
vegetative cover, no-till cropping practices, and less
reliance on cover improvement and terraces could reduce
erosion in the area by an additional 32 percent with the same
level of funds. A variable cost-sharing approach to erosion
control may yield even bigger dividends in a targeting
program.

Abstract: As the role of nonpoint-source contamination of
surface waters becomes more evident, increasingly more
attention is focused on the effects of agricultural practices
on soil erosion and water quality. Tillage systems are known
to affect the amount of water moving over the surface and
through the soil. This study compared the contributions of
three tillage systems used in corn (Zea mays L.) production
with (i) sediment losses and surface runoff and (ii) the
potential for nonpoint-source surface water pollution from N
and P fertilizers and triazine herbicides. Tillage treatments
were no-tillage, chisel-plow tillage, and conventional tillage
(moldboard plow plus secondary tillage). The study site was on
a Maury silt loam (Typic Paleudalfs). Over the 4-yr period,
conventional tillage runoff volume was 576.7 kL ha-1, chisel-
plow 205.7 kL ha-1, and no-tillage 239.9 kL ha-1. Total soil
loss from conventional tillage was 19.79 Mg ha-1, chisel plow
0.71 Mg ha-1, and no-tillage 0.55 Mg ha-1. Amounts of NO3(-),
soluble P, and atrazine leaving the plots in surface runoff
were greatest from conventional tillage and about equal from
chisel-plow and no-tillage. The magnitudes of the losses in
surface runoff water were small for all chemicals measured.

Abstract: The feasibility of using starch-encapsulated
atrazine to minimize convective transport under conditions
favoring preferential flow was evaluated. Forty small,
undisturbed, soil columns (45 cm2 X 3 cm) were removed from an
established no-tillage management site and randomly grouped
into one of five atrazine treatments: 1) technical grade; 2)
borate process, starch-encapsulated; 3) jet-cooked, pearl
starch-encapsulated; 4) jet-cooked, waxy starch-encapsulated;
and 5) untreated control. Columns were drip-irrigated at the
rate of 2.5 cm every three days. Highest atrazine levels, 1.30
mg L-1, were observed in the effluent from columns receiving
technical-grade atrazine after the first irrigation (2.3 pore
volumes), even though piston flow theory indicated that
atrazine should not have appeared before 21.9 pore volumes.
Computer simulations using the general convection-dispersion
equation with first-order dissipation and linear adsorption
also significantly underpredicted atrazine mobility. All
encapsulated formulations, relative to technical-grade,
revealed significantly lower initial atrazine levels in the
effluent. Cumulative effluent concentrations indicate that
after 16.1 pore volumes, 35, 10, 3, and < 1% of the available
atrazine had been leached from the technical-grade, borate,
pearl, and waxy starch formulations, respectively.

Abstract: Bioavailable P (BAP) in agricultural runoff
represents P potentially available for algal uptake and
consists of soluble P (SP) and a variable portion of
particulate P (PP). Evaluation of the impact of agricultural
management on BAP in runoff will aid assessment of the
resultant biological productivity of receiving water bodies.
Soluble P, PP, and bioavailable PP (BPP) (estimated by NaOH
extraction) were determined over a 5-yr period in runoff from
20 unfertilized and fertilized, grassed, and cropped
watersheds in the Southern Plains. Soluble P, BPP, and BAP
loss in runoff was reduced by practices minimizing erosion and
runoff, with respective mean annual amounts ranging from 237
to 122, 1559 to 54, and 1796 to 176 g P ha-1 yr-1 (for peanut-
sorghum [Arachis hypogaea L.-Sorghum bicolor (L.) Moench] and
native grass watersheds, respectively). However, as vegetative
cover improved, BAP (SP plus BPP) comprised a larger portion
of total P (TP) loss (29% for peanut-sorghum and 88% for
native grass). This results from an increasing contribution to
BAP of SP (13% for peanut-sorghum and 69% for native grass
watersheds) and BPP to PP (26% for peanut-sorghum and 69% for
native grass watersheds). Clearly, P bioavailability is a
dynamic function of physiochemical processes controlling
erosion, particle size enrichment, P desorption-dissolution
reactions, and plant residue breakdown, in addition to soil
and fertilizer P management. Hence, the change in trophic
state of a water body may not be adequately reflected by TP
inputs only. To more reliably evaluate the biological response
of a water body to agricultural P inputs, particularly from
conservation tillage practices, it may be necessary to
determine BAP in runoff.

Abstract: Water quality information regarding wheat culture
in the Southern Plains is sparse. The objective of this study
is to determine the extent to which the area's surface and
ground-water quality is influenced by different wheat cultural
practices. Concentrations and amounts of sediment, N and P in
surface runoff water were determined for conventional till
(CT), reduced till (RT), and no till (NT) wheat (Triticum
aestivum L.) watersheds in the High Plain, Reddish Prairie,
and Rolling Red Plain land resource areas of Oklahoma and
Texas. During the 4 to 6 yr study periods, RT and NT practices
were superior to CT for reducing sediment and associated
particulate nutrient discharge. Mean annual discharge ranged
from 230 to 15 900 kg ha-1 for sediment, 1 to 27 kg ha-1 for
total N, and 0.1 to 6 kg ha-1 for total P. Irrespective of
tillage practice, annual soluble nutrient losses in surface
runoff water tended to be small, often < 1 kg ha-1 N or P.
Successful prediction of soluble P, particulate P, and
particulate N losses was achieved using appropriate kinetic
desorption and enrichment ratio procedures. Soluble N in
runoff posed no particular water quality problem, but
recommended P levels were exceeded, even from baseline,
unfertilized grassland watersheds. With regard to groundwater
quality, elevated levels of NO3- (e.g., 34 mg N L-1 maximum)
were observed on one Reddish Prairie NT watershed.

Abstract: Impacts of water table management (WTM) practices
on water quality were modeled using a linked version of CREAMS
and DRAINMOD (Parsons and Skaggs, 1988). The CREAMS
denitrification component and the linked DRAINMOD-CREAMS model
were modified to simulate daily hydrology (runoff,
infiltration, evaporation, and soil moisture content),
erosion, and nutrient processes for different WTM conditions.
Measured data from Baton Rouge, Louisiana, were used to
validate the linked model, and then controlled drainage-
subirrigation (CD-SI) was simulated to investigate the effects
of different WTM systems on runoff, erosion, and nitrogen
losses. Results of the study indicated that the linked models
performed better than the original CREAMS model in predicting
runoff, infiltration, soil moisture content, and erosion, and
that the modified linked model performed better than both
CREAMS and the original linked model in predicting nitrogen
losses from the study site. Results also showed that the CD-SI
system simulated by the modified DRAINMOD-CREAMS model
predicted increased denitrification and lowered nitrate
leaching, unlike the original version. This study concluded
that the CD-SI system may be used as a BMP to reduce nitrogen
leaching to shallow groundwater systems for areas with high
water table conditions.
