Kilis İli Tarım Topraklarının Beslenme Durumunun İncelenmesi.

In this study, the productivity level of agricultural lands in the central and district villages of Kilis province was investigated. For this purpose, texture, pH, EC, CaCO3, organic matter, phosphorus and potassium analyzes were made in the samples taken from 0-30 cm depth of the soil. To determine some physical and chemical analyzes of the soil, 40 soil samples were evaluated in terms of productivity. According to the findings, the agricultural soils of Kilis province have a slightly alkaline reaction, 55% are clayey, 30% are clay loam, 15% have loam texture, 12.5% of the soils are very low in terms of organic matter content. 50% were in the low, 32.5% moderate and 5% good class. It has been determined that the agricultural soils of Kilis province are generally unsalted, 2.5% lime, 67.5% moderately lime, 22.5% highly lime and 7.5% too high lime. It has been revealed that high lime content in agricultural soils limits the availability of some important nutrients such as phosphorus. Agricultural soils in Kilis province have sufficient potassium, 24% of them have very low phosphorus content, 14% are low and 2% are in the middle class. For a continuous and efficient plant production, the nutrient removed from the soil must be added to the soil again. Producers Kilis province produce in these soils with high lime and low organic matter without fertilization. Nutrients in the soil are consumed by plants over the years. As a result of this process, the fertility of the soil decreases and the product yield decreases. Producers of our province limit the use of mineral fertilizers for economic reasons. Due to the weed problem, farm manure is not preferred. According to the results of the soil analysis, the required amount of fertilizer should be applied during the periods when there are nutritional problems in the agricultural lands where field crops and vegetables are grown in Kilis and when the plants need it. In addition, importance should be given to the use of organic fertilizers and thus sustainable fertility of the soil should be ensured. [ABSTRACT FROM AUTHOR]
