Residue Management POLLUTANTS ADDRESSED: Nutrients and Organics, Salinity, Sediments

DESCRIPTION: Residue management is the management of the amount, orientation, and distribution of crop and other plant residue on the soil surface year round while growing crops. Various forms of residue management include no-till, strip till, mulch, ridge till, direct seeding, and seasonal residue management.

LAND USE CLASSIFICATION: Agricultural lands POTENTIAL TREATMENT AREAS: Agricultural lands

LOAD REDUCTION MECHANISM: Nutrients/Organics Management- Nutrients and organic matter derived from plant residues becomes incorporated into the soil rather than draining to adjacent waterways. Salinity Reduction- Residue management stabilizes the soil, reduces erosion, and reduces the transport of soil salts to adjacent waterways. Sediment Reduction – Residue management protects the soil from erosion by reducing mud splash and runoff. ADDITIONAL BENEFITS: Residue management practices reduce energy and time costs for farmers. Moisture is conserved in the soil. Soil compaction can be reduced. Strategies manage available moisture to increase plant damage from freezing or desiccation.

residue producing crops and crop varieties, by the use of cover crops, and by adjustment of plant populations and row spacing. When planting in a low residue seedbed, completing tillage and planting in a single operation, or by performing primary tillage no more than three days before planting can minimize exposure to erosion; and in limited moisture areas, can conserve moisture for germination.

3. Leaving standing stubble taller than the six inch minimum will increase the amount of snow trapped. Leaving one or two rows of unharvested crop standing at intervals across the field can enhance the value of residue for wildlife habitat. Unharvested crop rows have the greatest value when they are adjacent to other cover types, such as grassy or brushy areas or woodland.

PLANNING AND IMPLEMENTATION: Riparian Planting Zone: Upland Zone and Flood flows. 1. Removal of plant residue by baling or grazing may have a negative impact on resources. These activities should not be performed without full evaluation of impacts on other resources. 2. Production of adequate amounts of crop residue necessary for the proper functioning of this practice can be enhanced by selection of high
