Sheep grazing on crop residues increase soil mineral N and grain N uptake in subsequent wheat crops

To determine the impact of sheep grazing on stubbles during the summer fallow period on soil properties, crop resources and growth under no-till, controlled traffic cropping with strict weed control.本研究旨在探究夏季休耕期绵羊啃食作物残茬，对采用严格杂草防控的免耕（no-till）可控交通种植（controlled traffic cropping）体系下的土壤性状、作物资源及作物生长的影响。
