5919. Rogers, P. and R.D. Roe. 1986. Effects on soil erosion and wildlife habitat potential of changing to higher residue crops in the intermediate precipitation zone, Whitman Co., WA.. unpublished paper.
Effects on soil erosion and wildlife habitat potential of changing to higher residue crops in the intermediate precipitation zone of Whitman County, WA. Soil erosion in the intermediate precipitation zone has been identified as more severe than zones with more or less precipitation. An example 960 ac farm in the intermediate precipitation zone is used to predict the effect of increased crop residue on soil erosion and wildlife habitat. Increased crop residue use by continuous cropping in this zone in Whitman Co. will reduce ave. annual sheet and rill erosion on an example 960 ac farm from 12 T/ac to 5 T/ac by changing from wheat-barley-fallow rotation to one of 4 years each of grain and grass. The wildlife habitat potential would increase to 62.5% of optimum potential from a previous low of 12.5%. The result is reduced soil erosion and improved habitat for wildlife. T: predicted sheet and rill erosion; comparison of present wheat-barley-fallow rotation with a rotation of 4 yr spring grain and 4 yr grass.

7693. Yan, Ying. 1989. A model for predicting soil loss ratio and crop production in eastern Washington. M.S. Thesis, Dept. of Agronomy and Soils, WSU, Pullman, WA.
The model (SHUI) predicts soil erosion and crop production under different crop rotation, tillage operation, and crop residue management conditions. It simulates the soil-water budget, crop and root growth, top dry matter production, grain yield, and residue production and loss, and predicts the soil loss ratio. Validation data are included.

10040. Wohld, M.. 1991 Mar.. Good farming practices reduced erosion this winter.. Washington Farmer-Stockman, p. 22-23..
Erosion would have been worse after the winter of 1990-91 if it had not been for good erosion control measures such as strip cropping, divided slopes and straw residue management. Strip cropping and divided slopes alone can reduce erosion by about 50%. Leaving as little as 200 pounds of straw residue on the surface per acre can have some positive impact on erosion, according to WSU research. Strip cropping is also important for moisture conservation.

The proceedings consists of more than 280 scientific papers on dryland farming. Subject areas include sustainability, soil erosion, water conservation, agroclimatology, soil fertility, residue management, socioeconomic issues, environmental issues, cropping systems, and crop/livestock systems.
