Özet:

The purpose of this study is to determine the state of efficiency of the land of the Ankara University Ziraat Faculty of Ayaş Research and Application Farm, for this purpose 44 land samples were taken from the intersection points of 100x100m grids and the physical and chemical characteristics of the land and the nutrient content were determined. In the creation of the distribution maps of the land samples received, the ArcGIS 10.3 software program and the IDW method were used in this program. In general, the soil is in the cylindrical class, contains light alkaline reaction, saltless, medium-degree cylindrical. 56% of the soils are organic, 29% of the total nitrogen, 99% of the bor potassium, and in terms of the iron and manganese content, the whole soils are insufficient. All of the soils contained baker, zinc and potassium, and 77% of the soils contained sufficient amounts of P. As a result of the correlation analysis; the positive relationship between kil-kum, sand-kum, kil-kum, kil-kum, kil-Fe, kil-Zn, silt-N, silt-Cu, pH-EC and silt-Cu, sand-kum, sand-Fe, sand-Zn, kil-Cu, EC-N, P-K, P-Zn, K- Zn and Fe-Zn was determined. According to the results of the soil analysis, microelement-contributed fertilizers must be applied to the areas needed to fix plant nutrient deficiencies. In addition, it is also recommended the use of mature farming fertilizers to improve the physical and chemical properties of these soils.
