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.

3570. Kent, R.L.. 1957. Conservation crop rotations in the PNW.. J. Soil Water Conservation, 12(6): 269.
Experimental data and observations indicate that crop rotations with grass and legumes is needed in the wheat-pea area. Also of importance are strip croping, contour operation, stubble mulching, early seeding of winter wheat. T: comparison of OM, water loss, soil loss from virgin land and crop land.

8384. Beus, C., D. Dillman, and J. Carlson. 1990. Palouse agriculture: a survey on production practices, policies, and problems.. unpublished results, Dept. of Rural Sociology, Washington St. Univ., Pullman, WA 99164.
This random survey was done in the Palouse area of eastern WA and northern ID, with a random sample of about 260 farmers. Average farm size was 1392 acres. One-third of the respondents would like to change their current rotation, primarily to reduce disease problems, but consider government programs to be the biggest barrier. Desire to use no-till planting was evenly split. Half the respondents felt they were using most of the available erosion control practices. Large percentages (>60%) felt that contour tillage, surface roughness, no-till, good plant cover, and tilth were very important erosion control factors. Herbicide and fertilizer use trends over the past five years were normally distributed. Use of fungicides on wheat (other than seed treatment) was generally less than 20%. Half the farmers currently use soil testing, and of those, 90% tested for residual N to 4-5 ft. depth. Half the respondents felt they had cut back on pesticide and fertilizer use since their high point, while only 10-20% felt they would do so in the future. About 65% had heard of the LISA program, and 26% indicated opposition to it.
