2645. Hoag, D.L. and D.L. Young. 1986. Commodity and conservation policy impacts on risk and returns.. Western J. Agric. Economics 11:211-220.
Crop yields, farm income risk and returns, and soil losses were simulated from 1974 to 1984 for southeastern WA Palouse-region farms in 3 climatic subregions under alternative conservation and commodity policy scenarios. Historical commodity programs reinforced preexisting disincentives to retire highly erodible land to perennial grasses, but cropland base protection legislation would eliminate such disincentives and increase profitability and decrease risk of land retirement. Government rental payments can provide further incentives, but they are more costly without cropland base protection.
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.

In a survey of 225 farms, different soil conservation practices were documented. "Inertia, insufficient farm income, lack of appreciation of the seriousness of the situation, or an attitude of indifference toward soil conservation even though the situation is recognized" are some of the reasons for the limited effort made to conserve soil. Some look at the situation from the short-term viewpoint and apparently have no interest in the future. T: Number of farmers reporting use of selected conservation practices.
5725. Rasmussen, V.P. and R.L. Newhall. 1989. High residue conservation tillage increases soil moisture and profits. IN: Utah Agricultural Statistics, 1989. p. 121-124. Utah Agricultural Statistics Service, Salt Lake City, UT.
Three years of data are reported for several locations comparing a number of consevation tillage and cropping systems. The no-till and chemical fallow were better both for conserving soil and moisture, and generated the highest net returns. The chem fallow conserved about 1-2 inches of soil moisture. Erosion under the no-till chem fallow ranged from 1-5 T/ac compared to 17-30 T/ac with conventional tillage. The study included tests of continuous cropping, but more years are needed to make an economic comparison.
6776. Taylor, M.C. and V.W. Baker. 1947. Economic aspects of soil conservation in the Palouse wheat-pea area.. WA Agr. Expt. Sta. Bull. #494.
The objective of this study was to measure the effect of the conservation program on farm income during the sixth year of a 6-yr period. The purpose was to evaluate the economic effects of the program currently recommended for the area and to contribute information for the improvement of conservation planning. It was found that there was no significant relationship of current farm income to the total conservation inputs over a 6-yr period. There was no significant or consistent relationship of crop yields or labor and machinery requirements to conservation inputs. It was noted, however, that by slight shifts in land use and farm organization the higher conservation score farmers were able to maintain net incomes comparable to those of other farmers. T: Percentage of crop land in grass-legumes on 69 sample Palouse farms by conservation score groups, 1941 to 1946. Percentage of crop land in sweetclover used as green manure crop on 69 sample Palouse farms by conservaton score groups, 1941 - 1946.
