Is ESN recommended for use on all acres?

ESN is designed for soil and environments that are at risk for N-loss and where nitrogen is a limiting factor for growth. The added value of ESN may not be realized in soils that have other limiting factors such as compaction, drought, flooding, imbalance of other nutrients and excessively high or low pH. ESN does not correct existing problems in the soil other than the loss of N from traditional sources.  ESN may have some benefits not related to N loss that results from continuous feeding and controlled-release nitrogen supply.
