Abstract

We estimated soil erosion by water in the major land resource areas (B7, B8, B9) of eastern Oregon. Combinations of tillage and crop residue handling, terracing, and contouring were evaluated as control alternatives. Soil erosion exceeded tolerance limits in the wheat-fallow sequence on slopes over 20% even with all 3 management inputs. All 3 management inputs were needed on slopes between 12 and 20%. Tillage and residue management, along with contouring, sufficed on slopes less than 12%.-from Authors
