4R Nutrition and Farm Net Profits
Retailers and their farmer customers want to manage their farms so that they are sustainable, and the key indicators of farm sustainability are its Social, Environmental, and Economic goals and outcomes, writes Tom Jensen, Director, North American Program, International Plant Nutrition Institute. Individual farms vary in size. But all farms need to be managed so that they contribute to society, help look after the environment, and function economically so the farm is profitable and contributes to the local economy.
The use of 4R Nutrient Stewardship is succinctly described as managing nutrient inputs on a farm in a way that the Right Sources of Nutrients are applied at the Right Rate, Right Time, and Right Place. Often the environmental aspects of these principles are initially easier to understand, and social contributions to the persons living on the farm and stakeholders in society are important, but economic viability is vitally important to sustainability.
