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 unpublished results, Dept.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.

8476. Brown, D.. 1990. USDA scientist announces farming breakthrough.. News, WSU CAHE Information Dept., WSU, Pullman, WA 99164.
Dr. Jim Cook announced a new one-pass no-till system that appears to solve some of the disease problems of the past. The drill uses paired rows 7" apart, with 17" between pairs. By placing a fertilizer shank in each row, rather than in the middle of the pair, soil diseases are discouraged and young diseased roots can still reach fertilizer and grow past the damage.

11007. Moore, K.J. and R.J. Cook. 1984. Increased take-all of wheat with direct drilling in the Pacific Northwest.. Phytopathology 74:1044-1049.
Take-all occurred more frequently or more severely on consecutive wheat crops seeded no-till into undisturbed stubble compared to plots with moldboard or disk plowing. This held true at three different climatic locations, for two seasons, and for winter and spring wheat. Differences in soil temperature and moisture could not account for the effect, nor did additional fertilization. Disease with no-till apparently was increased because of more infested debris and because the inoculum source was ideally positioned for infection of the crop.
