Abstract
For many years, agronomists have used the Canadian Fertilizer Institute Nutrient Uptake and Removal guidelines for estimating fertilizer requirements to match and balance crop requirements with nutrient removal. These guidelines have been revised and updated over the years with most of the revisions based on the data collected several years ago from research plots. There is a need to update the data to ensure that the guidelines reflect current crop varieties and yields, fertilizer application rates and crop management practices in farm fields. Additionally data regarding micronutrient uptake and removal is needed. Our project aims to revise crop macro- and micronutrient uptake and removal guidelines for fourteen crops grown in Western Canada, based on samples collected from commercial fields across MB, SK and AB. The project is ongoing with preliminary Year 1 results available from the 2020 and 2021 field seasons.
