Soil Fertility Guide

Soil Testing
Growers who follow soil test recommendations can expect higher fertilizer efficiency, more balanced nutrient levels for crops, and optimum benefits from their lime and fertilizer investments. Soil testing should be the first step in planning a sound fertilization program. With a soil test, the guesswork of knowing how much lime and fertilizer to apply is eliminated. A soil test can identify yield-robbing fertility problems.

Lime and pH
One of the most important steps to a successful crop management program is to adjust the soil pH (acidity) of the soil to an optimum level. A low pH limits the uptake of nutrients found in the soil and causes additional applications of fertilizer to not work efficiently. A low pH can be corrected with the addition of ag lime to the soil.

* Legumes get most of their nitrogen from the air bottom of form.

** Figures are total amounts taken up by the crop in both the harvested and the above-ground unharvested portions. These numbers are estimates for indicated yield levels, taken from research studies, and should be used only as general guidelines.
