5362. Power, J.F. (ed.). 1987. The role of legumes in conservation tillage systems.. Soil Cons. Soc. Amer., Ankeny, IA. 153 pp..
Proceedings of a national conference, University of Georgia, Athens, April 27-29, 1987. Excellent reference for the use of legumes in cropping systems and their compatibility with conservation tillage. Major sections include: the need; germplasm resources; nitrogen source; insects and diseases; cropping practices; weed control; erosion and productivity; economics.

794. Bezdicek D.F., C.S. Root, E. Kirby and D. Granatstein.. 1987. Tillage and cropping systems alternatives for high rainfall areas. STEEP - Conservation Concepts and Accomplishments.
A number of alternative cropping and tillage options were evaluated in a 3 year study near Pullman. Superior wheat-yields were obtained from red clover residue that was shallow tilled. Yields were much lower for the same residues which were chemical killed. Most yields did not respond to additions of fertilizer N to residues. T: Dry matter production, plant N, N fixed, soil, inorganic N, and soil water prior to tillage in 1985. Residual soil water under various crops prior to tillage in fall. Winter wheat yield in 1986 as affected by type of green manure residues, tillage, and N.

4484. Michalson, E.L.. 1987. Tillage and cropping systems alternatives: Economics and productivity. p. 437-446.. IN: L.F. Elliott (ed.). STEEP - Conservation Concepts and Accomplishments. WSU Publications..
In most cases farmers would face cost increases by adopting conservation practices. This provides a rational for state/federal intervention to offset costs. The economic emphasis of soil conservation has shifted from the value of tons of soil to the farmer to the cost of tons of sediment to the public. T: Economic comparison of winter wheat/spring pea rotation with winter wheat/spring barley/spring pea rotation. Economic comparison of conventional vs. no-till on a 3000 acre summer fallow wheat farm in southwest Idaho. Estimated income above the variable costs, per yield levels.

6957. USDA. 1978. Palouse cooperative river basin study.. SCS, FS, ESCS - USDA.
Excellent summary of soil erosion problem and possible management approaches in the Palouse; extensive data on land use, soil erosion, future scenarios; history of agriculture in the area; bibliography.
