​Soil sampling allows knowing what’s in your soil, identifying and treating soil variability, maximizing fertilizer use efficiency, and maximizing crop productivity. These purposes can be thwarted, however, when soil sampling is performed at the incorrect depth, uses improper tools, provides too much variation, and includes too few cores, as well as when soil moisture and sample timing are not addressed.
