Cederbaum [10] reported higher densities of breeding birds in conservation-tillage cotton fields as compared to conventional tillage, especially with conservation tillage fields using strip cropping.


What are the benefits of conservation tillage?

The use of conservation tillage systems provides economic, environmental and social benefits .


How does conservation tillage benefit wildlife?

Conservation tillage systems, other than the things listed above, provide a social benefit by increasing habitat for wildlife including deer, ground-nesting birds and other wildlife. The social benefits are also related to cleaner air from reduced soil movement during wind storms and cleaner water from reduced erosion.


How does conservation tillage work?

Conservation tillage systems work on both soil and water environments. On the soil, as the tillage decreases, soil organic matter increases which aids in increased water infiltration from precipitation or supplemental irrigation, increased soil micro and macro organisms and reduced runoff to mention a few benefits. In the water, conservation tillage systems reduce erosion which keeps sediment out of waterbodies. Under most conditions runoff is reduced except when the soil is saturated; however, even if runoff is not reduced, sediment movement is reduced. As this sediment movement is reduced, the movement of nutrients and pesticides is reduced.


What is conservation tillage?

”. By this definition, conservation tillage is any tillage practice that builds up crop residues on the soil surface to minimize the impact


What is the role of crop residues in conservation tillage?

The use of conservation tillage requires the management of crop residues on the soil surface. Crop residues, a renewable resource, play a key role in conservation tillage.


How to manage crop residue?

The Natural Resources Conservation Service (NRCS) in the Southeast provides these additional considerations that deal primarily with management of crop residues or other residues [23]: 1 Uniformly distribute loose residue in the field. Do not burn residue. A minimum of 30 percent coverage is needed to prevent erosion. Coverage of 50 percent or greater is recommended to conserve soil moisture and increase organic matter. 2 Use planters and drills that can plant through untilled residues or into a tilled seedbed prepared using approved implements. Do not disturb more than one-third of the row width when planting or fertilizing. 3 Equip combines and harvesting equipment with spreaders that are capable of spreading residue over 80 percent of the header width. The header is the part of the combine that harvests the crop. Limit removal of residue from baling or grazing to retain the recommended amount of residue on the soil surface.


What is a ridge till?

Ridge-till: Specialized planters and cultivators are used to form and retain permanent ridges on which cash crops are grown. Crops are planted on the top of the ridge after removing residue, which is left between ridges. Cultivation is used to form and maintain ridges, and to manage weeds.


How much coverage is needed for soil erosion?

Uniformly distribute loose residue in the field. Do not burn residue. A minimum of 30 percent coverage is needed to prevent erosion. Coverage of 50 percent or greater is recommended to conserve soil moisture and increase organic matter.
