Abstract: Vine branches, rice husks and flax residues were composted. The dynamics of biomass carbon, C/N ratios and nitrification were studied. The highest quality level and the most stabilized composts with the highest values of total N (1.3- 1.6%) and the smallest C/N ratios (8.0-9.0) were found with the vine branch composts. Compost application significantly increased the yield of tomatoes (24.0-61.1%) and the quality of fruits compared to soil treated with mineral fertilizers and manure. Inoculation of the vine branch compost with a Cephalosporium sp. had a positive effect on the yield and the quality of both ryegrass and tomatoes. The stabilization of the microbial biomass C level in the composts coincided with the beginning of intensive nitrification. Inoculation lowered the conductivity values and nitrate contents in all composts. It appeared that when nitrate N concentrations in the composts were more than 5% of the total N, NO3 accumulation in the fruits could result. However, the results can be applied to similar substrates and conditions of composting.

Abstract: Two field experiments were conducted to examine the agronomic value of poultry manure composted in the presence of both phosphate rock (PR) and elemental sulphur (So) (sulphocompost) and PR alone (phosphocompost). Winter cabbage and summer maize were used as test crops. For the first season's winter cabbage, the phosphocompost and sulphocompost were approximately 12% and 60% as effective as urea and both composts were equally effective as urea for the second season's maize crop. The greater agronomic effectiveness of sulphocompost could be attributed to the improved nitrogen (N)-use efficiency increased PR dissolution and improved S nutrition. Distribution of nitrate-nitrogen (NO3-N) in the soil profile of field plots indicated greater potential for winter leaching of N from urea than poultry manure which could be the reason for the improved residual value of the manure reflected in summer maize yields. The results from the field experiments indicated that composting poultry manure with So and PR not only reduces environmental pollution associated with manure application, but also increases the agronomic effectiveness of manure.

Alternatives for the disposal of poultry carcasses.

Includes references.
Descriptors: poultry farming; waste disposal; carcass disposal; rendering; fermentation; composting; extrusion; burial; incineration
Abstract: Every broiler production facility is faced with the reality of carcass disposal. Nationwide, this represents a tremendous amount of organic matter that requires environmentally and biologically safe disposal or utilization. Disposal of poultry carcasses has been identified as one of the major problems facing the poultry industry. If poultry carcasses resulting from death by natural occurrences at such high levels of production are not disposed of by environmentally acceptable methods, future industry expansion will be limited or regulatory constraints will be imposed. Methods for the disposal of poultry carcasses include burial, incineration, composting, and rendering. Burial and incineration impose environmental concerns that are becoming less acceptable. Composting is environmentally sound, relatively inexpensive, and is gaining widespread acceptance. Rendering carcasses into a valued protein by-product meal is another alternative. Methods for transporting fresh or refrigerated carcasses to a rendering facility are being investigated. When coupled with rendering, fermentation is an excellent alternative for storing and sporting pathogen-free poultry carcasses. Extrusion of carcasses provides an alternative to conventional by-product rendering. AD methods that allow for the environmentally safe and biosecure disposal of poultry carcasses should be considered. No single method will completely solve the problem.

Abstract: Poultry litter is composted to reduce odor and pathogens and to improve its quality as a soil amendment. Organic material, e.g., sawdust, is added to increase the C:N ratio to achieve optimum degradation of organic C and retention of N through microbial biomass formation. However, the relative biodegradabilities of the organic material in poultry litter and the amendment are usually not known. Furthermore, it is assumed that as microorganisms metabolize organic compounds and produce CO2, they increase in biomass and, therefore, retain N. In this study, bench-scale compost reactors were used to determine the relative contributions of poultry litter and of the amendment (sawdust) to the biodegradability of a compost mix. Approximately 29% of the volatiles lost from the poultry litter mix came from the sawdust. Fiber analyses revealed that only a small portion of cellulose was degraded. Although microbial subpopulations able to degrade selected macromolecules were present at varying levels, the overall level of microorganisms did not change markedly. Populations capable of degrading bacterial cell walls were present throughout the composting period, and microbiological assays indicated that inorganic nutrients were available to support limited microbial growth. These results suggest that N compounds and inorganic nutrients are recycled, rather than fixed during composting.

Abstract: Composting and active drying are the main techniques employed to prevent losses of NH3 and development of undesirable odours from poultry manure. We studied the effects of these treatments on C and N content and stabilization of organic matter. Carbon and N contents of composted poultry manure (CPM) at the end of the processes were 82.9 and 56.1%, respectively, of the initial material, whereas the C content of dried poultry manure (DPM) remained practically the same, while the N content slightly increased with time. Nitrogen content of DPM at the end of the process was about three times higher than that of CPM (55.1 and 19.2 mg/g, respectively). The humification index (HI) showed a decreasing trend in both products, indicating the formation of humic substances in both processes, although to different extents: even at 20 days CPM showed HI values typical of a well-matured material (0.50), whereas HI for DPM at the end of the process was 1.14, indicating that this material did not achieve stabilization. Application of electrofocusing (EF) to characterize the qualitative evolution of humic substances showed a more complex EF profile in the case of CPM and confirmed the higher stabilization of OM in the composted material. CPM could be useful as a soil amendment because of its high degree of stabilization, whereas DPM can be considered mainly as an organic fertilizer, because of its high content of N. If DPM was piled for a long period its OM could achieve a high degree of humification, so increasing the agronomic quality of this fertilizer.

Abstract: The objective of this study was (a) to detect changes of the functional abilities of the microflora during composting of manure as a result of windrow turning frequency and (b) to detect differences between distinct zones within the windrows. Biolog GN microtiter plates containing 95 different carbon sources were inoculated with diluted suspensions of compost material containing 15,000 microorganisms per well (120 microliter). We found a dramatic shift in functional microbial community structure during the 8-week composting process. The shift was more rapid when the compost windrows were turned. The substrate use pattern in the outer, well-aerated zone of the unturned windrow was similar to that of the turned windrows. Microbial biomass and respiration decreased more rapidly in the turned than in the unturned windrows, indicating a different pace of compost maturation. The data suggest that the Biolog assay may be a suitable approach to determine compost maturity.

Abstract: To uncover possible chemical differences between stockpiled and composted dairy manures, water extracts of these manures were analyzed by 13C nuclear magnetic resonance (NMR) and by pyrolysis-field ionization mass spectrometry (Py- FIMS). Judging from the 13C NMR, which took into consideration all of the organic C present, aliphatic and aromatic C in the composted and stockpiled manure extracts were similar but the composted manure extract appeared to be richer in protein C, phenolic C, and carboxylic C and poorer in carbohydrate C than the stockpiled manure extract. Major components of the extract of the stockpiled manure extract determined by Py-FIMS, which measured only volatile organics, were N compounds > phenols + monolignins > carbohydrates > alkylaromatics > peptides = lipids > lignin dimers > sterols > fatty acids > suberins. On the other hand, the quantitative order of organic components of the composted manure extract was phenols + monolignins > N compounds > carbohydrates > peptides > alkylaromatics > lipids > fatty acids > sterols = lignin dimers > suberins. The relatively low total ion intensity of the water extract of the composted manure and its greater aromaticity suggested that composting increased polymerizathin and cross-linking and so led to the formation of larger molecules. Water-soluble organic C (DOC) extracted from the manures was used to study adsorption isotherms on soils varying in clay content from 3 to 54%. The adsorption of the DOC by the soils increased as the clay and organic matter contents and the surface areas of the soils increased. Increased adsorption of the DOC extracted from the composted manure appeared to be due to increased molecular weights.

Abstract: A nitrogen transport and mass-balance study was performed at a large-scale composting facility in order to evaluate the impact of such facilities on groundwater quality. In the soil zone, soil moisture NO3-N concentrations in excess of 100 mg/L were consistently observed at depths as great as 1.5 m below a farm waste windrow, and reached levels as high as 900 mg/L by the end of the composting process. There was a strong inverse relationship between NH4-N changes in the farm waste and NO3-N changes in the soil directly below the windrow. Little attenuation occurred as NO3-N was transported downward through the soil. NO3-N in soil moisture 1.5 m below the yard waste remained at ambient levels for much of the two-month sampling period. Quantified nitrogen losses during the composting process were nearly 10 times higher in the farm waste than in the yard waste. Of the nitrogen species sampled, dissolved NO3-N was by far the predominant pathway for nitrogen loss from the composting farm waste, while gaseous N2O losses predominated in the composting yard waste. The major factors determining the degree to which nitrogen was lost during the composting process were waste characteristics of: the type of organic carbon present, the percentage of inorganic nitrogen, the bulk density, and moisture content.

Abstract: The physical and chemical properties of litter and its compost were investigated for two broiler management systems. Management practice one removed all litter after each group of birds, while management practice two removed litter after every third group of birds. Both practices had mass reductions due to composting of approximately 25%. Management practice two had higher concentrations (dry basis) of all chemical constituents, except nitrogen (N) and total organic carbon (TOC). The concentrations of chemical constituents, except Al and TOC, increased due to composting. The litter and the resulting compost showed significant differences for both management practice one and two. However, the characteristics of the compost produced from management practice one were similar to the characteristics of the compost for management practice two.

Abstract: The effects of various bulking agents were examined on the efficiency of composting the fibrous solids obtained from swine manure after a liquid/solids separation process. The effects on the quality of the resulting composts were also examined. The separated solids were either composted without bulking agents, or mixed with different portions of peat moss and/or sawdust. Aeration rates were also varied in different experimental sets. A self-heating mode of operation was adopted. The results indicated that the fibrous solids from a liquid/solids separation process could be composted in small reactors with or without the addition of bulking agents. The composting masses reached thermophilic temperatures (45-70 degrees C) and met regulatory requirements with or without aeration. Aeration rates of 0.04 to 0.08 1/min per kg volatile matter and an intermittent mode of aeration are recommended for the composting of separated swine manure. Based on measured compost characteristics and composition, the finished composts made from a manure/peat moss mixture had the best quality in terms of moisture content, nitrogen content, carbon-to-nitrogen ratio and colour of the product.

Descriptors: maize; poultry manure; aflatoxins; microbial degradation; detoxification; composting; temperature; moisture content; ammonia
Abstract: Two trials were conducted to determine whether deep stacking of contaminated corn with poultry litter destroys aflatoxin. Contaminated corn was ground and mixed with litter to carbon:nitrogen ratios of 30:1. Moistures were adjusted by adding tap water just prior to incubation or stacking. The initial laboratory trial included only broiler litter at 40% moisture, whereas the subsequent field trial involved a 2 X 2 factorial design with litter type (turkey or broiler) and moisture (20 or 40%) as main effects. Aflatoxin assays were reduced in the laboratory trial from 433 and 402 to 54 and 8 ppb in Containers 1 and 2, respectively, after 35 d of incubation at 28 C. In the field trial, aflatoxin disappeared from broiler and turkey litter mixtures with projected moistures of 20% after 10 and 6 wk of storage, respectively, whereas disappearance in mixtures containing projected moistures of 40% required 5 and 3 wk, respectively. Differences in moisture appear to account for differences in the ability of turkey and broiler litter to detoxify aflatoxin. Hence, turkey and broiler litter would appear equal with respect to the ability to detoxify aflatoxin- contaminated corn. Disappearance of aflatoxin during storage with litter could have occurred as a result of ammonia release during storage or microbial detoxification mechanisms. However, nitrogen values suggest that microbial action was responsible for much of the detoxification, as aflatoxin disappeared from mixtures with little apparent ammonia release.

Abstract: Dissolution of phosphate rocks (PRs) during composting with poultry manure was examined using a radioactive 32p labelled synthetic francolite and North Carolina phosphate rock (NCPR) through laboratory incubation experiments. Francolite or NCPR was mixed with different poultry manure composts at a rate equivalent to 5 mg P g-1 and the dissolution was measured after 60 and 120 days incubation by a sequential phosphorus (P) fractionation procedure. The use of 32p labelled francolite showed that in manure systems, PR dissolution can be measured more accurately from the increases in NaOH extractable P (deltaNaOH-P) than from the decreases in HCl extractable P (deltaHCl-P) in the PR treated manure over the control. The dissolution measurements showed that approximately 8 to 20% of francolite and 27% of NCPR dissolved during incubation with poultry manure composts in the presence of various amendments. Addition of elemental sulphur (S degrees) to the compost enhanced the dissolution of PRs. The results provide no evidence for the beneficial effect of protons (H+), produced during the nitrification of NH4+ in manure composts, on PR dissolution. The low level of dissolution of PR in poultry manure composts was attributed mainly to the high concentration (4.8 X 10(-2) mol L- 1) of calcium (Ca2+) in manure solution.

Abstract: The effective cation exchange capacity (ECEC) of manure composts, at the start and during the composting process, were determined. During this study we developed a new saturation-displacement principle based method for compost samples. It was clearly demonstrated that ECEC of manure compost, as analyzed from three successive composting series, profoundly increased as compost matured. In addition, the ECEC values were highly repeatable, due to the proper mixing of the matrix with the saturation, washing, and displacement solutions, as well as to the preventing of any matrix losses with the separation of the matrix from those solutions with careful centrifugation-filtration procedure.

Abstract: Emissions of harmful gases, malodorous compounds and greenhouse gases emitted during composting of swine feces under continuous aeration were studied using a laboratory- scale composting apparatus. Concentrations of ammonia and sulfur compounds in the exhaust gas rose remarkably after starting and at every turning, and their changes reflected the odor concentrations calculated from sensory tests. Volatile fatty acids, in high concentrations at the start, were rapidly reduced within several hours from starting and did not rise again. Methane emission was observed within only 1 day from starting. Nitrous oxide repeatedly rose and fell after every turning, as did ammonia. From the viewpoint of nitrogen loss during composting, however, the total amount of nitrous oxide emission seemed quite small compared with that of ammonia.

Abstract: The chemical and agrobiological characteristics of 37 composts from wheat straw with different additives were evaluated through routine tests. In general, the plant yield under greenhouse conditions in soils amended with these composts was unrelated to data from the phytotoxicity germination biotest, but with the chemical parameters reflecting selective biopolymer degradation in straw. This suggests that factors such as microbial immobilization of nutrients had greater influence than phytotoxic inhibitor compounds in the plant yield of the soils amended with the composts studied. Monitoring the composition of the water-soluble fraction was also useful as regards crop yield of soils improved with compost. The factors potentially connected with the positive or depressive effect of composts in soil were assessed through factorial design experiments involving successive harvesting, calcium carbonates and mineral fertilization. In general, mineral fertilization may lead to decreased yields in soils to which immature composts are applied. The effects on compost maturity of the different by- products used as additives are discussed for the system studied.

Abstract: The agrobiological properties of 37 composts prepared from wheat straw with a series of organic or mineral additives have been determined through standard chemical analyses and greenhouse experiments with soils of different carbonate content and in the presence, or absence of mineral fertilization. Plant yield on soils treated with the composts was studied in successive stages of development of rye grass (Lolium rigidum), showing significant differences that paralleled the values of a limited number of compost parameters. Under greenhouse conditions and in the presence of mineral supply, the least matured composts led to improved plant yield only in the early harvests, decreasing thereafter which points to a behavior typical for the microbial immobilization of the additional nutrients. The germination (phytotoxicity) index was found poorly correlated with the yield in the different soils, whereas the N and lignin contents provided the most significant information, the results suggesting no cause-to-effect relationship in such correlations. The multiple regression models showed significant differences as regards the system studied when the limiting influence of nitrogen (N) was reduced through additional fertilization. The most significant coefficients for the plant yield were those reflecting the total mineralization rates of the compost, the composition of the water-soluble fraction, and the concentration of lipids whereas, when no mineral solution was added, the yield was explained mainly by the N content in compost and in water-soluble products. In successive harvests, the significance level of the compost N level tended to increase, whereas that of lipid decreased, the former factor showing the greatest influence when carbonates are present in the soil.

Abstract: An outdoor study was undertaken using polyethylene containers to assess the suitability of different organic residues, soybean straw (Glycine max L. Merrill), wheat straw (Triticum aestivum L.), maize stover (Zea mays L.), chickpea straw (cicer arietinum L.) and city garbage, as food for the tropical epigeic earthworm Perionyx excavatus, and to assess the influence of this earthworm on the decomposition of these materials. Maize stover was found to be the most suitable of the food materials used. Population growth of P. excavatus was enhanced by addition of these organic materials in the temperature range 24-30 degrees C, while the population was adversely affected above 30 degrees C in a vermiculture system. Addition of earthworms accelerated the breakdown of residues, which ultimately resulted in a lowering of the C:N ratio, water- soluble carbon and carbohydrates, and increased ash percentage and cation exchange capacity compared with their respective controls.

Descriptors: cattle slurry; humic acids; soil organic matter; composting
Abstract: Humic substances (HS) were extracted from separated cattle-manure compost (CSM) at various stages of decomposition. Carbon-13 nuclear magnetic resonance (13C-NMR) and Fourier-transform infrared (FTIR) spectroscopy measurements were performed on the purified humic acids (HA) as well as crude fiber and chemical analyses. Levels of HS extracted from the CSM samples doubled during the composting (from 377 to 710 g kg-1 organic matter [OM]). The HS were divided into: (i) HA, which increased from 184 to 457 g kg-1 OM; and (ii) a fulvic fraction (FF). The FF was separated on XAD-8 resin to: (i) fulvic acid (FA), which maintained an unchanged level during composting (80- 100 g kg-1), and (ii) a nonhumic fraction (NHF), which increased from 107 to 170 g kg-1 OM during the process. The ratios between the concentrations of these fractions were tested as humification indexes. These indexes changed significantly during the process and were found to correlate exponentially with the composting time, C/N ratio, or both. Quantities of low-molecular- weight components (FF and NHF) rapidly increased during the first 40 d of composting and were nearly constant thereafter. The HA and HS contents reached nearly constant values after approximately 90 d. Only slight compositional and structural changes in CSM HA were detected with cross-polarization magic- angle spinning (CPMAS) 13C-NMR, FTIR spectra, and chemical analyses. The elemental composition and functional groups of CSM RA resembled those reported for HA of plant residues, peats, and incompletely humified materials. The CPMAS 13C-NMR spectra of the CSM HA resembled that of lignin. The aromaticity of the HA was about 40% and the lignin content was approximately 60%. The NMR data correlated web with results obtained by FTIR spectroscopy, both indicating that the CSM HA are composed of partially degraded constituents of plant tissue, which still retain to some extent their chemical structures. The major plant components identified in the HA were lignin, carbohydrates, and long-chain aliphatic structural groups.

Abstract: Long-chain fatty acids in germination- inhibiting animal-waste composts were identified by gas chromatography-mass spectrometry as myristic, palmitic, stearic, oleic, linoleic, and linolenic acids. These acids were found at concentrations greater than 0.25 mg (g dry compost)-1. The identified acids, together with lauric acid, and five kinds of short- and medium-chain fatty acid, were tested for their effects on the germination process of sorghum seeds. The authentic long- chain fatty acids, which were dissolved in a 1: 9 (v/v) mixture of methanol and distilled water at 40 mg liter-1, significantly reduced the alpha-amylase activity, physiological water uptake, and ATP content of the germinating seeds during the first 24 h of imbibition, as well as the rate of germination of seeds. Among the tested fatty acids, myristic and palmitic acids were the most potent inhibitors of germination. The inhibitory effects of long-chain fatty acids were stronger than those of the phenolic acids. The short- and medium-chain fatty acids did not have any significant germination-inhibitory effects at 40 mg liter-1. The results indicate that the long-chain fatty acids are the dominant inhibitors of germination in animal-waste composts, and that the inhibition of the alpha- amylase activity in germinating sorghum seeds is one aspect of the mode of action of these long- chain fatty acids.

Abstract: Natural and passive aeration methods of composting under high initial moisture content condition (76%) were studied. Compost material consisted of poultry manure slurry as the waste and peat as the bulking agent. Piles were trapezoidal in section with an initial volume and height of 5 m3 and 1.2 m, respectively. Correlation factors of temperature readings of identical positions in replicate piles showed that the process was quite stable and reproducible. Influence zone of passive aeration pipes was limited to the interior portion of the bottom half of the pile. Temperature distribution inside the piles indicated that passive aeration pipes were effective in providing more air than natural aeration. Passive aeration process finished two weeks earlier than natural aeration process. The final product had a dark brown color and was rich in total nitrogen and phosphorus.

Abstract: Farm residues with high C:N ratios are difficult to use because of their low economic value and excessive volume. Composting is ideal for upgrading such residues, but was not thought possible without co-composting or lowering of the C:N ratio. We developed a low-input method to compost perennial ryegrass straw on-farm by forming windrows and fuming them either zero, two, four, or six times throughout the year with a commercial, straddle-type turner. No water beyond normal rainfall and no N other than that contained in the straw was added. The volume of straw was reduced by up to 88% with four or six turns over 20 to 24 weeks. The average internal temperature of straw windrows reached a maximum of 54 degrees C with four turns. The ability to compost these residues will help in the development of sustainable farming systems by allowing recycling of straw waste.

Maturity assessment of wheat straw composts by thermogravimetric analysis.

Includes references.
Descriptors: wheat straw; composts; decomposition; thermal degradation; thermogravimetry
Abstract: Thermogravimetric analysis in oxidizing atmosphere has been used to characterize composts prepared from wheat straw with different organic and mineral additives. After a wide range of classical parameters were determined for the chemical maturity of composts, plant yield improvement was studied in a greenhouse experiment. It was found that most chemical and agrobiological maturity indices paralleled peak area values in the differential thermogravimetric curves. In particular, the weight loss corresponding to compost material destroyed between 360 and 540 degrees C showed a very significant correlation with the germination index and the plant yield of the soils amended with compost. As expected, the extent of such thermal effects reflected also the H/C, O/C, and C/N ratios and the lignin content of the composts. Experiments during the methodological optimization of thermogravimetric analyses have shown the importance of removing the compost water- soluble fraction to prevent spurious results, probably due to the effect of salts on thermal decomposition in the lignocellulosic substrate.

Abstract: Long and short straw from grass seed production fields were collected, formed into windrows, and turned with a commercial compost turner zero, two, four, or six times over a nine-month period. Internal temperature and volume reduction of windrows were monitored weekly from October 1992, to June 1993. Volume was reduced by as much as 88% for long-straw windrows and 80% for short-straw windrows. Near- maximum volume reductions were achieved with as few as four turns for the short straw and two turns for the long straw. Number of turns had a significant effect on the rate of volume reduction. Four or more turns were necessary to produce a compost product with a soil- like texture. Temperatures necessary to kill all seed contained in the compost were not achieved and use of the compost should be limited to situations where crop and weed seedlings are not a concern.

Abstract: The changes in microbial properties, including total aerobic heterotrophs, O2-consumption rate, ATP content, dehydrogenase activity and microbial biomass C and N of the spent pig-manure sawdust litter were examined during further composting. The effects of three moisture levels, 50% (pile A), 60% (pile B) and 70% (pile C), on the composting process were also evaluated. Piles A and B had very similar trends of change in temperature and microbial properties during the composting period but pile C was significantly different. Temperatures in the first two piles increased to a peak of 64-69 degrees C by day 4, while that of pile C rose to a lower peak (58 degrees C) on day 7. The high moisture content (about 70%) of pile C led to early cooling of the pile and decreased the production of microbial activity and biomass. Although water was added frequently to maintain the moisture content of each pile, it was difficult in practice to maintain the moisture content of pile C at 70%, since water leaked out from the pile. Therefore, a moisture content of between 50 and 60% can be considered as the optimal moisture level for further composting of the spent litter. In general, the total aerobic heterotrophs, O2 consumption rate and ATP content of all piles increased dramatically during the thermophilic stage of composting, but then decreased slowly and were maintained at lower levels at the end of the composting process. Stability of microbial properties was observed at day 60, indicating that two months is enough to convert spent litter to a mature compost. Temperature was found to be correlated with ATP content, dehydrogenase activity and oxygen consumption rate, and so these parameters could be used to indicate.

Microbial C and N dynamics during mesophilic and thermophilic incubations of ryegrass.

Abstract: Laboratory studies were conducted to determine C and N dynamics during the decomposition of ryegrass straw under mesophilic and thermophilic conditions. A K(C) of 0.61 was developed for the chloroform-fumigation extraction method to estimate microbial biomass C. These estimates showed that the C and N requirement of the thermophilic biomass was approximately 50% of the mesophilic biomass. There was no relationship between chloroform-fumigation microbial biomass estimates and plating of microorganisms from straw on specific media. Mineralized C was measured as 185 and 210 g kg-1 straw in the 25 degrees C and 50 degrees C treatments, respectively. The efficiency of microbial substrate use, on a total straw basis, was 34 and 28% in the 25 degrees C and 50 degrees C incubations, respectively. The level of soluble C declined more slowly than total C mineralization at both temperatures, indicating that a portion of the labile C was not readily biodegradable. The addition of N decreased the rate of C mineralization at both temperatures. The reduced N requirement of the thermophiles explains why rapid degradation of the high C:N residue occurred without additional N or the need for the addition of a low C:N ratio substrate. Additional inoculum did not affect the decomposition process. We conclude that the promotion of thermophilic biomass activities, through composting for example, may prove useful in upgrading agricultural wastes for introduction into sustainable cropping systems.

Abstract
: The composting of oil palm empty-fruit-bunches and of oil palm empty-fruit-bunches in supplementation with either goat dung, cow dung or chicken manure differed in the resulting C:N ratios. The initial C:N ratios (52:1, 35:1, 48:1, 47:1) for the four compost heaps were significantly reduced to 24:1, 14:1, 18:1 and 12:1, respectively, after 60 days of composting, resulting in the production of a stable humus that is suitable for crop production. A temperature of 70 degrees C was maintained for 3 days at the onset of composting. Both mesophilic and thermophilic bacteria showed consistent activity throughout the process, whereas fungal activity was completely suppressed during the peak heating phase. The rate of utilization of cellulosic material showed a positive correlation with the increase in the nitrogen content of the compost.
