"Accurate soil samples are key," says Dick. "The AutoProbe mechanizes the process and assures this. Fertility plans are only as good as the weakest link in the chain. Good soil samples are the most important basic information that must be gathered. The AutoProbe takes away the human error. You know you're getting the same number of probes at the same depth across each grid or zone. It just makes good sense to use the AutoProbe on such an important link in the fertility chain when shooting for the highest yields."
