Conservation Practices
These bibliographies cover various agricultural conservation practices
such as conservation tillage, cover crops and stream
restoration. The bibliographies focus on how practices
affect erosion and sedimentation, nitrogen, pathogens,
pesticides, phosphorus, and fish and wildlife -- 2000
to present.

Conservation Buffers
"Strips or small areas of land in permanent vegetation, conservation
buffers help control potential pollutants and manage other environmental
concerns. Filter strips, field borders, grassed waterways, field windbreaks,
shelterbelts, contour grass strips, and riparian (streamside) buffers are
all examples of conservation buffers." From: Buffers,
Common-Sense Conservation.

Conservation Tillage
"Any tillage and planting system that covers [an area of] soil surface
with crop residue, after planting, to reduce soil erosion... Two key factors
influencing crop residue are (1) the
type of crop, which establishes the initial residue amount
and its fragility, and (2) the type of tillage operations prior to and
including planting."
From: Agricultural
Chemicals and Production Technology: Glossary.

Cover Crops
"Cover crops are plants grown during the off-season when cash crops are not being produced." Cover crops and 'green manures' provide ecological services such as weed suppression and pest management. Researchers develop agricultural management systems utilizing the optimum mix of cash crops and cover crops. From: Cover Crop Research at the Sustainable Agricultural Systems Lab.

Drainage
"Agricultural drainage is the removal of excess water from the soil surface and/or soil profile of cropland, by either gravity or artificial means. The two main reasons for improving the drainage on agricultural land are for soil conservation and enhancing crop production." From: Understanding Agricultural Drainage.

Fencing and Livestock Exclusion
Fencing and livestock exclusion refer to the practice of "excluding livestock from a specified area to protect, maintain, or improve the quantity and quality of plant, soil, animal, and water resources." From: Use Exclusion: Livestock.

Integrated Pest Management
"Integrated pest management (IPM) is the implementation of diverse methods of pest controls, paired with monitoring to reduce unnecessary pesticide applications. In IPM, pesticides are used in combination with other crop management approaches to minimize the effects of pests while supporting a profitable system that has negligible negative effects." From: Integrated Pest Management: Overview.

Irrigation
Irrigation [water management] is the "process of determining and controlling the volume, frequency and application rate of irrigation water in a planned, efficient manner." From: Irrigation Water Management (NRCS Conservation Practice Standard No. 449).

|
|
|

Manure Management
Manure management combines the "physical aspects of nature such as rainfall, temperature, and soil characteristics; constructed features such as ponds and water ways; and a concerted management strategy to protect or enhance the ecological setting of the animal enterprise." From: Animal Manure Management.

Nutrient Management
Nutrient management manipulates "the amount, source, placement, form
and timing of the application of plant nutrients and
soil amendments" with
the goal of benefiting plant production; maintaining
the physical, chemical and biological condition
of soil; and reducing adverse environmental impacts.
From: Nutrient
Management (NRCS Conservation
Practice Standard No. 590).

Stream Restoration
Stream restoration "is the process of returning a [stream] ecosystem as closely as possible to predisturbance conditions and functions… The restoration process reestablishes the general structure; function; and dynamic, but self-sustaining, behavior of the ecosystem." From: Ecological and Physical Considerations for Stream Projects (Introduction), Stream Restoration Design (National Engineering Handbook Part 654).
