The Neglected Option in Choosing the Right Fertilizer: 20.32.0+15 (SO3)+Zn and Soil Analysis Support

The prosperity of their forecasting studies often increase the quality of forecasting. This article discusses the causes and consequences of a compound fertilizer that has been recommended to be produced in 1999 and which has been produced since 2004, but not yet consumed at the estimated level. In Turkey, farmers especially prefer the compound fertilizer containing nitrogen and phosphorus in pre-sowing and sowing fertilization cereal production. This prefence has led farmers to use DAP and 20.20.0. compound fertilizers extensively. The compound fertilizer (20.32.0+15 (SO3)+Zn) we proposed in 1999 and produced since 2004 is a true alternative that provides a more favorable nitrogen/phosphorus (N/P2O5) for some cereal fields. But awareness is very limited. The average annual consumption for the last three years is around 19 thousand tons, which is below our expectation. Increased number of qualified fertilization recommendations based on soil analysis, this and the fertilizer that will be produced in the chose proximity to the N/P2O5 equilibrium will give the consumption chance in a increasing quantities. This increase we expect may reduce economic losses due to unbalanced nitrogen-phosphorus. Our knowledge and observations point to the fact that soil and plant analysis support in Turkey has a very special value. Prior to chemical fertilizer consumption support, the application quality of soil and plant analysis support should be improved. In this way, fertilization can be done based on the result of the analysis. As a result, chemical fertilizer use efficiency will increase
