1219. Caplan, A.J.. 1986. Cost return and relative soil loss comparisons of alternative tillage systems.. MS Thesis.
Minimum tillage is less expensive than conventional. No-till is most expensive due to high chemical inputs. In the low precipitation zone, minimum till was 1.19 times less expenxive than conventional. Annual peas/wheat in high precip. zone was 1.5 times less expensive with min-till than conventional.

5899. Rodman, A.W.. 1988. The effect of slope position, aspect, and cultivation on organic carbon distribution in the Palouse.. MS Thesis, Dept. of Agronomy & Soils, WSU, Pullman, WA.
Soil organic carbon (OC) was studied at 4 sites, native and cultivated. At the native site aspect had the greatest influence on OC levels. At the cultivated site OC distribution is due to water and tillage erosion. All topsoil had been eroded from south slopes. Perennial grass rotations had added OC above and below the surface while reducing OC loss from erosion and oxidation. Strip cropping and uphill plowing resulted in a greater depth of OC. T: Average surface organic carbon values by slope position.
