Fertility status of land in Erzurum province, Tortum distric

The study was conducted to the fertility status (nutrient supply capacity) of agricultural soils depending on the level soil fertility parameters of selected in the Tortum district of Erzurum. For this purpose, soil samples at a 0-30 or 0-60 cm were collected from 55 different points of the research area . Fifty five soil properties (Macro nutrients; total nitrogen, available N,P, K,Ca,Mg,Na micro nutrients; available Fe, Cu,Zn, Mn ) and other soil properties (texture class, organic matter, pH,electrical conductivity, CaCO3 content) were evaulated. The findings obtained as a result showed that; Textural distributions of agricultural lands of Erzurum ili Tortum county; 33% sandy loam, 25% clay loam, 22% sandy clay loam, 7% loam sand, 7% loam, 4% clay and 2% silt loam. The pH of the soil samples is neutral and mildly alkaline, the soil organic matter content is high and very slightly salty. It has been determined that 47% of the soils are nitrogen, 14% is potassium, 19% is calcium, 22% is magnesium, 47% is iron, 14% is zinc and the whole plant is manganese. The result was is sufficient for the available P and Cu. pH, salt, CEC, K and available Zn in the soil with lime; P, salt, KDK and pH with organic matter; pH, Zn, KDK and plant availability P; With KDK, clay, sand, salt and plant are available P; K, sand and silt with clay and plant availability; Silt with sand and usable Cu in the plant; Organic matter with zinc, N, Ca, Na, Fe, Cu, Mn; Iron and organic matter, N, Ca, Na, Cu, Zn, Mn; pH with magnesium, K, Ca; Significant relationships between manganese and organic matter, N, Ca, Na, Fe, Cu, Zn have been determined.
