Physico-chemical Evidence of Soil Quality from Southeastern part of the Ovče Pole Wine Region

This study summarizes the physico-chemical analysis of 18 soil samples collected from vineyards in the Southeastern part of the Ovče Pole wine region. The samples were collected from three different locations at the depth of 0-30 cm to determine their chemical, structural and nutritional properties. Basic soil parameters were analyzed, including pH, electrical conductivity (EC), organic carbon (OC), organic matter (OM), moisture, and carbonate content. Additionally, the analysis of macronutrients (N, P, K) and microelements was measured using (ICP-MS) technique. To determine the soil type, a structural analysis was performed. From the obtained results it can be observed that the soil is slightly alkaline (pH values range from 7,1 to 8,6), with moderate organic matter content and low nitrogen levels (average 1,10 g/kg). The carbonates content varies in the range of 0,31-40,8%. Phosphorus and potassium content varies between location in ranges from 24,5-50,1 mg/100g for K and from 8,44-42,9 mg/100g for P, while the content of microelements suggest potential limitation in the availability of certain essential nutrients. The soil in the studied region is moderately structured (varies from sandy soil to silty clay loam) which affects its water permeability and ability to retain nutrients. This analysis provides valuable information about soil fertility and structure in vineyards in the Southeastern part of the Ovče Pole wine region, which can be used for optimizing fertilization management and improving sustainable grape production.
