4R Nutrient Stewardship – Manitoba

Crop Types
  • Whole Farm

Nutrients are essential inputs for crop production. Nutrient management planning helps optimize production and minimizes the risk of nutrient loss from agricultural lands. When certain nutrients, particularly phosphorus, enter surface water and eventually other water bodies, they stimulate the growth of algae and aquatic plants.

Implementing the 4R Nutrient Stewardship (Right Source @ the Right Rate, Right Time, and Right Place®) in Manitoba is crucial to protecting farmland and waterways. Manitoba is taking steps to ensure these sustainable practices are being implemented by actively promoting the principles and practices of 4R Nutrient Stewardship and encouraging Manitoba farmers to implement these practices to increase their economic return and protect the environment while ensuring a growing economy.

Fertilizer Canada recognizes how valuable water is to communities and that sustainable, environmentally conscious practices need to be adopted to protect this irreplaceable resource. To accomplish this goal, Fertilizer Canada provided $150,000 over three years to help fund e-learning, workshops, interactive learning tools and the establishment of 4R Farmer Advocates in Manitoba.

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 (Right Source @ Right Rate, Right Time, Right Place ®) provides a framework to achieve cropping system goals -increased production, increased farmer profitability, enhanced environmental protection and improved sustainability. 4R Nutrient Stewardship requires the implementation of best management practices (BMPs) that optimize fertilizer use efficiency. The goal of fertilizer BMPs is to match nutrient supply with crop requirements and to minimize nutrient losses. The selection of BMPs varies by location, and those chosen for a given farm are dependent on local soil and climatic conditions, crop, management conditions and other site-specific factors.

4R Designation provides recognition for farmers who complete and apply 4R Nutrient Stewardship grower plans.
