Afficher plus [+] Moins [-]Soil properties are an important part of the complex framework in the crop production system. Soil properties may vary over short distances, but are related to position within the landscape. This study investigated the relationships among pH, salinity, bulk density, horizon thickness, depth to carbonates, and soil moisture according to landform position. Four catenas were studied under different crop rotations: summerfallow-canola-wheat, summerfallow-wheat-wheat, continuous cereals, and continuous cereals plus a legume. Total plant biomass and crop yields were determined on hand harvested samples from each slope position. Best yields in 1989, generally occurred in back and shoulder slopes and lowest yield in footslope areas that were flooded out by intense summer showers.
