Monitoring soil nitrate to estimate cover crop nitrogen contribution in organic vegetable production fields

Creator:: Andrews, Nicholas, Sullivan, Dan M., and Pool, Kristin
Abstract:: Organic vegetable growers rely on legume cover crops as an economical source of plant-available N. This research evaluated N contributions to summer vegetable crops by cover crops (CC) residues by monitoring soil nitrate (NO3-N) concentrations during the summer crop growing season. Replicated field plots were established with three CC mixes:...
