Soil sample handling practices can affect soil nitrate test accuracy
The accuracy of a soil test is limited, in part, by the quality of the tested sample. However, soil samples must also be handled properly after they have been collected. Results from a recent study at K-State illustrates what can happen when soil sample submission to a testing lab is delayed and samples are not properly stored.
