5434. Pubols, B.H., A.E. Orr and C.P. Heisig. 1939. Farming systems and practices and their relationship to soil conservation and farm income in the wheat region of Washington.. WA State Ag. Exp. Sta. Bull. #374.
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.
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.

Predicts soil carbon changes in different climatic zones under various agroforestry management schemes. Can be used for prediction of changes under other land use as well.
8422. Anon.. 1990. Gully washers show strip value.. Whitman Co. Gazette, Colfax, WA p. 9. 7/19/90.
Several cloudbursts in Whitman Co. during May and June moved 150-200 tons of soil per acre off slopes. Some flats were covered with six to 18 inches of sediment. Rills and gullies that started on summer fallow strips were mostly blocked or dissipated by the cropped strips below. A field that had been chiseled but not rodweeded did not erode at all. On long summer fallow slopes, there were gullies 30 inches wide and a foot or more deep.
