Determination of Plant Nutrition Capacities of Agricultural Areas by Soil Analysis: Example of Süleymanpaşa District of Tekirdağ Province

Soil is one of the most important components of agricultural production. Therefore, healthy soils are increasingly needed for food security, nutrition goals and combating climate change. Soil health is critical to both ecosystem balance and human life. Soil not only supports plant growth, it also performs many important functions, from storing water to sequestering carbon. In addition, soil health is a critical factor not only for agriculture and food production but also for general environmental health, combating climate change and sustainable development. In this study, it was aimed to determine the sustainable productivity capacities by evaluating the analysis results of 60 soil samples taken from the fields in Süleymanpaşa district of Tekirdağ province, which were exposed to intense agricultural activities with wheat-sunflower rotation. The average pH, total salt, organic matter and lime contents of the samples taken were determined as 7.28, % 0.40, % 1.29 and % 3.62 respectively. It was determined that the majority of the soils (47 units) were in the "loam" texture class. The total N contents of the soil samples were determined as the lowest % 0.02 and the highest % 0.15. The average P, K, Ca, Mg, Fe, Mn, Zn and Cu contents of the soil samples were determined as 14.94, 211.68, 5393.15, 408.86, 13.60, 12.71, 0.88 and 1.05 mg kg-1 respectively. When the average organic matter and total N contents in the samples were evaluated, it was determined that they had low levels of organic matter and total N contents. Considering the average values of the soil samples, it was determined that they were "high" in terms of Ca and Fe; "low" in terms of Mn and "sufficient" in terms of P, K, Mg, Zn and Cu. The biggest benefit of these studies is that, the correct use of fertilizer also has positive benefits in terms of economy and the environment. For this reason, organic fertilizers must be included in the fertilization programmes of soils with low organic matter.
