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

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.
