Crop residue grazing and tillage systems effects on soil physical properties and corn (Zea mays L.) performance

Abstract Crop-livestock systems under no till (NT) could negatively affect soil physical properties and crop performance, due to the additive effects of reduced soil cover and cattle trampling due to livestock grazing, and the absence of tillage. We evaluated the effects of four grazing strategies a...
