Given the decrease in meadowlands and animal production and the increase in acreage planted to annual crops, good conservation practices such as the use of cover crops are important to preserve soil health and water quality. Six demonstration plots were set up on farms in eight outlying and more central regions in Québec. In each region, a demonstration plot showcased the ability of undersown clover cover crops to reduce nitrogen fertilizer requirements and another presented their ability to reduce weed pressure and the need for herbicides. A number of demonstration days, videos, and documents with testimonials from growers about the impact of the cover crops complemented the demonstration plots.
From 2016 to 2018
As part of this project, growers were visited in nine Québec regions to promote the use of clover as a cover crop.

The project compared the nitrogen uptake effects of green manure crops grown for a full season, in association with a main crop, or after it is harvested.
In a wheat/grain corn/soya rotation, green manure can be used to obtain profitable organic grain corn yields while limiting phosphorus pollution.

This project evaluated the impact of various corn, soya, and wheat fertilization methods on marketable yields, harvest quality, nitrate losses, and movement of microorganisms potentially pathogenic for humans.
