The substance that contains the minerals necessary for the nutrition of plants and that enables plants to be fed more easily from the soil by regulating the physical and chemical structure of the soil is called fertilizer. Fertilizer formed from animal waste, fossils and similar natural means is called organic fertilizer. As a result of scientific research, it has been determined that the excessive increase in the use of nitrogenous fertilizers in agricultural areas causes an increase in nitrate and nitrite in the foods produced, and that the risk of cancer for people who eat these foods increases. For this reason alone, the use of chemical fertilizers is banned in many European countries. Chemical fertilizers and chemical pesticides thrown into the soil not only harm harmful insects, but also harm and kill birds, other harmless insects and beneficial microorganisms in the environment. It provides resistance to the soil and plants with the components contained in organic fertilizers. It increases the efficiency of products. In our country, the fertilizer needs of soils vary depending on regional conditions and the crops planted in previous years. For this reason, before fertilizing, a "soil analysis" should be done by taking samples from the soil, and then a "fertilizer analysis" should be performed on the organic fertilizer to be used. If there is any fertilizer remaining depending on the needs of the plant planned to be produced, only the missing part should be completed with package fertilizer. However, according to the research conducted by the Ministry of Agriculture, approximately 140,000 soil analyzes were carried out in Turkey, except for the Black Sea Coast and Northern Thrace regions, which receive a lot of rainfall. According to the analysis of approximately 140,000 soils, our country's soils are high in lime, high in pH and very poor in terms of organic matter, and are also low in phosphorus and potassium. It was determined that it was too much but could not be purchased. Additionally, iron and zinc deficiencies have been detected in terms of trace elements.
