Nitrogen is a mobile nutrient. If we apply too much, we risk polluting our groundwater and spending too much money. If we apply too little we risk not maximizing our yield for the year. One of the ways to more accurately apply your nitrogen is to first take deep soil samples to determine how much residual nitrogen you have left over and how deep in the soil profile it is. We are able to sample down to 36 inches to help pinpoint your nitrogen needs.
