Prairie Nutrient Removal Calculator

This nutrient removal calculator estimates the nutrients removed in the harvested seed or grain. The removal coefficients are based on survey data collected from commercial fields from 2020-2022 in Saskatchewan, Alberta and Manitoba. The coefficients are estimates only and are based on the 75th percentile of the survey data for each nutrient. Research has shown that nutrient concentrations in the harvested seed or grain varies from year to year and with crop variety, soil fertility and climatic conditions. Consequently, these estimates are not prescriptive and should be used in conjunction with regular soil testing.
