Why are lime recommendations not what I expect after changing soil test pH?
Problem Description: After entering the crop rotation into a field, the user goes back and modifies the soil test information, changing the pH. Since pH affects lime recommendations, it’s natural to expect this change will affect the lime application amount shown on the soil test report, but it does not. When the user revisits the field’s crops and edits them in the Plant Crops screen, hitting the calculate button doesn’t produce the expected lime recommendations. Answer: This is a complex fake-out that occassionally surprises people. The problem is that NutMan automatically inserts lime applications in the plan when you OK out of the Plant Crops screen. At that time it calculates the lime recommendation based on the soil test pH and any lime applications already applied to the field. If you go back and change the field’s pH later, NutMan doesn’t automatically remove or change these automatically inserted lime applications. This is why just changing the pH doesn’t change the lime amoun
