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:...

Refining nitrogen management for organic broccoli production

Creator:: Sullivan, Dan M., Peachey, Ed, and Donaldson, Andrew
Abstract:: Specialty organic fertilizers used in organic vegetable production are expensive. So, from environmental and economic perspectives, growers want to maximize nitrogen (N) fertilizer use efficiency by the crop. This research was conducted to (1) determine sufficient N fertilizer rates for organic broccoli, (2) evaluate the efficacy of a specialty organic...
