During application of nitrogenous fertilizers, significant losses occur due to the change of form of this element in soil. In order to prevent nitrogen losses and to make maximum use of this nutrient; it is generally recommended to apply the amount to be divided into several parts. Application in parts alone is not sufficient to reduce nitrogen losses. Slow release products prevent the nitrification process by means of its technology and minimize nitrogen loss. In this way, plants are fed more effectively, yield and quality increases.
