Determination of Some Properties of Cereal Cultivated Soils Based on Great Soil Groups in Isparta Province


1 Isparta Uygulamalı Bilimler Üniversitesi, Ziraat Fakültesi, Toprak Bilimi ve Bitki Besleme Bölümü, Isparta, Türkiye DOI : 10.21566/tarbitderg.660231 - In this study, some properties of soils used for cereal cultivation were investigated and evaluated based on the great soil groups. For this purpose, surface soil samples (0-30cm) were collected from 150 points in 6 different great soil groups. Sand, silt, clay, field capacity, wilt point, pH, EC, organic matter, CaCO3, K, Ca, Mg, Fe, Cu, Zn, Mn of soil samples were analyzed. According to the results; all soil groups cultivated crops were neutral-slightly alkaline reactions. These soils had salt-free properties and 78.5% of soils were in sandy clay loam texture class. It was found that the average field capacity was 22.87% and wilting point was 13.45%. Organic matter content was low at 77.8% of investigated soils. Ca, Mg, Zn deficiency in them were determined as 5%, 7.85% and 42%, respectively. While Mn and Cu contents were sufficient level, K and Fe levels were sufficient-high in soils. When the minimum and maximum values were evaluated, the highest variability was determined in Chestnut soils for field capacity and wilting point, and Colluvial soils for pH and EC. Regarding their nutrient content, there was no deficiency in Chestnut soil groups. The highest Mg and Zn deficiency was determined in Brown Forest soil.
