Covering the bases with cover crops

30 septiembre 2015

Instead of being harvested, many cover crops are returned to the soil. In this way their nutrients can be used by other crops. Legume cover crops, in particular, are an excellent source of nitrogen — a key nutrient for all plant life. Researchers find cover crop decomposition and nitrogen release vary with type of cover crop used and addition of poultry litter. Cover crops also control weeds and help to manage pests.
