4R Plant Nutrition Manual: A Manual for Improving the Management of Plant Nutrition

The 4R Plant Nutrition Manual - available both in North American and Metric unit versions - includes chapters on the scientific principles behind each of the four R’s or “rights”. It discusses adoption of 4R practices on the farm, approaches to nutrient management planning, and measurement of sustainability performance. The manual is intended to help the reader adapt and integrate the fundamental 4R principles into a comprehensive method of nutrient management that meets the criteria of sustainability. A mix of learning modules and case studies demonstrate the universality of the 4R Nutrient Stewardship concept through its application to diverse cropping systems used within small enterprises, large commercial farms, and plantations.
