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
