Abstract

This project set out to assess the practicality of using the on-farm plant testing procedures for P & K status of wheat developed at Rothamsted. The procedure was found to be straightforward and gave a reasonable indication of nutrient status. Its use on-farm would be best utilised in conjunction with the standard soil testing method as an interim check on nutrient availability. There is an opportunity on many farms with indices above 2 for P and K to run down reserves if monitoring is done regularly using plant testing in conjunction with soil analysis.
