4R Nutrient Stewardship in Manitoba

4R Nutrient Stewardship in Manitoba

At our 2021 Annual General Meeting Manitoba Crop Alliance Inc. (MCA) members passed a resolution titled “MCA to encourage a reduction of nitrous oxide gas emissions from soil and fertilizer use through a farmer-to-farmer soil and crop management learning forum.”

In response to the resolution MCA is striving to educate farmers about the 4R’s (Right Source @ the Right Rate, Right Time, and Right Place®) in Manitoba and provide them with tools and resources to make informed management decisions on their farms.

Together with Fertilizer Canada information about 4R Nutrient Stewardship will be available on our website and social media channels. These resources have been designed to educate farmers around nutrient management so they can make informed decisions on the farm to optimize production, help minimize the risk of nutrient loss, and reduce nitrous oxide emissions from agricultural lands.

Implementing 4R Nutrient Stewardship on your farm

Nutrients are essential inputs for crop production. Applying the 4R Nutrient Stewardship (Right Source @ the Right Rate, Right Time, and Right Place®) in Manitoba helps optimize production and is critical to protecting farmland and waterways. Farmers are encouraged to implement the principles and practices of 4R Nutrient Stewardship to increase their economic return and protect the environment while ensuring a growing economy.

What is 4R Designation?

Farmers are increasingly facing pressures from the supply chain and the general public to demonstrate on-farm stewardship. The 4R Designation program can provide a strategic opportunity to meet those challenges. 4R Nutrient Stewardship provides a framework to achieve cropping system goals -increased production, increased farmer profitability, enhanced environmental protection and improved sustainability.
