One effort to reduce nitrogen loss is to make the fertilizer in a form of slow-release. SRF method can be done conventionally based on centrifugal force. Nitrogen release from UZA fertilizers generally decreased during the incubation period. Urea fertilizer in the form of a slow-release combination of zeolite and humic acid is applied to soil media to reduce the rate of nitrate release. In this case, it is necessary to identify the effect of a release ready modifying zeolite and humic acid. Increase in the concentration of humic acid, the nitrogen content in the fertilizer before and after incubation in general decreased.
