Abstract:

The wealth of the forecast studies, often, improves the quality of the forecast. However, there is little research on the future of chemical fertilizers in Turkey. This article discusses the reasons and consequences why a composite fertilizer proposed in 1999 and started producing since 2004 has not yet been consumed at the expected level. In Turkey, farmers prefer composed fertilizers that contain nitrogen and phosphorus together, especially in the production of grapefruit before October or in the fertilization with October. This preference has directed farmers to use DAP and 20.20.0 composite fertilizers widely. We recommended in 1999, produced since 2004, 20.32. 15(SO3)+Zn fertilizer is the right alternative to a much more suitable nitrogen phosphoric balance for some fertilizer areas. The knowledge is very limited. The average annual consumption of the last 3 years is about 19 thousand tons, and this is below our expectations. The increase in the number of qualitative fertilizing recommendations based on the soil analysis will give the chance of increased consumption to the fertilizers that will be produced in properties close to the N/P205 balance in this fertilizer. This increase we expect to be will reduce economic losses due to the unbalanced use of nitrogen-phosphorus. Almost all of our information and observations indicate that support for soil and plant analysis in Turkey has a very special value.  More importantly than chemical fertilizer consumption support, the quality of application of soil and plant analysis support should be improved. This way, fertilizers can be made based on the analysis results. After all, the use of chemical fertilizers will increase.
