Description
The project compared the nitrogen uptake effects of green manure crops grown for a full season, in association with a main crop (organic corn or wheat), or after it is harvested. Physical soil properties, nitrogen availability, and nitrate losses were also monitored with and without controlled drainage.
Objective(s)
- Evaluate nitrogen inputs and soil profile improvements associated with five scenarios involving legume green manures
- grown for a full season
- in association with the main crop
- after the main crop is harvested
From 2016 to 2018
Project duration
Field crops
Activity areas
Soil health, Fertilizer management, Organic farming
Services
Green manure contributes to soil health.
