Abstract

Crop residue left on the soil surface after planting is a primary component of the majority of conservation plans developed to comply with the conservation provisions of the 1985 Food Security Act. During implementation of these plans, Extension clientele began to ask what influences cattle grazing had on residue cover. To help answer some of these questions, we measured percentage corn (Zea mays L.) residue cover remaining on the soil surface after grazing and after no-till planting during three planting seasons. Compared to non-grazed, undisturbed conditions, the amount of cover was reduced by an average of 26% (P < 0.001) by grazing and by 37/o (P < 0.001) when the residue was disturbed by the combination of grazing and planting. A simple grazing reduction factor of 0.43% · ha · day-1 · 1000 kg animal unit-1 (approximately 0.5% · acre · day-1 · 1000 lb animal unit-1) is proposed to estimate corn residue cover reduction due to grazing when site-specific values of percent residue cover are not available.
