The Challenge

Fertilizer costs contribute up to 30% of total variable costs in canola production. Little options are known that will both reduce fertilizer input expenses and improve soil nutrients without sacrificing yield.

The Project

Determine how different cropping systems, including a cover crop cocktail of diverse species, livestock integration, and the use of manure and foliar fertilizer can improve soil health, fertility savings, and carbon storage over a three-year period in both grey and brown soils.

The Results

When performing a benefit:cost ratio analysis, three treatments perform better than other cropping systems studied. These treatments include year-one cattle manure, year-one green manure crop, and annual application of bio-stimulants.

Grower Benefits

Using manure and foliar fertilizer can both increase yields and reduce fertilizer costs.
