When relying on nutrient recommendations from your soil and plant test results to plan your fertility program, do you know how accurate those recommendations are?
At the 2018 National No-Tillage Conference, John Grove explained that soil test results may not be as accurate as they could be if they aren’t correlated and calibrated for a no-tiller’s specific situation.
The University of Kentucky plant and soil scientist, as well as director of the university’s Research and Education Center in Princeton, Ky., discussed what no-tillers need to know about soil testing to get accurate recommendations. He also shared how tissue sampling can provide more information on their fertility program and how to utilize crop-sensing technologies to learn more about crop nutrition.
The first thing no-tillers need to keep in mind when taking a soil test is that because they’re in a no-till environment, there will be vertical differences due to nutrient stratification within the topsoil. Stratification takes place over time and this needs to be taken into account.
