How does soy fertility treatment work?
Most soil fertility treatments consist of the addition of specific nutrients such as nitrogen, phosphorus, or potassium at rates determined to be needed to optimize yield. These additions are added to supplement the nutrients that the plant will derive from the soil. N-Serve is an additive that is designed to reduce the rate of conversion of ammonium N to nitrate N. By doing this, one reduces the potential for N loss during excessively wet conditions. Books have been written on your questions. If you need more specifics, please go to your local library.
