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.

Subsoiling and temporary drainage in soils with low permeability
The project evaluated and compared the effectiveness of two types of subsoil plows (mounted on a bulldozer or a tractor) operated parallel and perpendicular to the tile drains to improve soil drainage conditions and productivity compared to control plots.
