The effects and decomposition of ammonium thiosulfate and guanyl thiourea, a nitrification inhibitor, are discussed. When ammonium thiosulfate and guanyl thiourea are used as nitrification inhibitors, leaching of ammonium nitrate from calcium ammonium nitrate in soil is reduced, while the yields and nitrogen intake of the plant are increased. When ammonium thiosulfate and guanyl thiourea are used, labor costs are reduced without any loss of product yield or quality. The use of ammonium nitrate products containing ammonium thiosulfate and guanyl thiourea reduced the nitrogen requirement for maximum efficiency.

In this study, the effect of ammonium thiosulfate and guanylthiourea on calcium ammonium nitrate and how it affects nitrogen concentration under fertilization conditions were discussed. however, the results obtained by monitoring the loss of nitrogen concentration and the change in nitrate and ammonium concentrations over a specified time period indicate that the ammonium thiosulfate and guanylthiourea used are the best choice as an inhibitor candidate.
