IPNI Estimates of Nutrient Uptake and Removal

This page lists estimates of nutrient uptake and removal for different crops grown in different countries of the world in both Imperial/U.S. and Metric units, and represent what IPNI scientists believe to be the best estimates of typical values to date. All tables are used within included in our 4R Plant Nutrition Manual. and are used within our Crop Nutrient Removal Calculator i-OS app (PlantCalc) and its web-based version.

These tables are updated as new data become available. You can download these tables in pdf format (see 'Additional Resources' on left).
