4R Nutrient Stewardship has been promoted and applied across Canada through a number of provincial and regional programs and initiatives. 4R Nutrient Stewardship is currently being practiced in: Alberta, Manitoba, Ontario, New Brunswick, and Prince Edward Island.
To fertilize properly and achieve the benefits of an abundant and healthy crop, professionals should follow the 4Rs of fertilizer use: Right Source @ Right Rate, Right Time, Right Place ®.
Canada’s diverse soils have helped to shape current farm practices. National projects help amplify the importance of applying 4R Nutrient Stewardship to farms. Provincial programs tailored to each region help farmers understand what practices best suit their conditions.
For example, what may be a recommended practice in Western Canada may not be recognized as a beneficial practice in Atlantic Canada. Environmental factors, such as soil, climatic conditions, crops, application rates, and timing vary greatly across the country. It is for this reason 4R Nutrient Stewardship is a site-specific program based on available science pertaining to land, air and water.
A number of environmental concerns related to agriculture are evident across Canada from excessive phosphorous loading, to nitrate levels in drinking water, to soil conservation, salinity, and greenhouse gas emissions concerns. As Canadians, we understand the importance of sustainable environmental solutions and one of the key benefits of 4R Nutrient Stewardship is minimizing environmental concerns related to agriculture.
