AGROCHEMICAL CHARACTERIZATION OF SOILS FROM THE OVCHE POLE VINE DISTRICT: A CASE STUDY FROM TRI CESHMI AND DOLNO TROGERCI

Abstract

This study provides a physicochemical, and agrochemical characterization of vineyard soils in the Ovche Pole Vine District, located within the Povardarie Wine Region of North Macedonia. Two representative vineyard locations, Tri Cheshmi and Dolno Trogerci, were selected for comparative assessment based on their contrasting geological conditions. The analysis focused on key soil parameters, including pH, electrical conductivity (EC), organic matter (OM), organic carbon (OC), calcium carbonate (CaCO₃) content, texture, as well as available nitrogen (N), phosphorus (P) and potassium (K). The soils in Tri Cheshmi, developed over Neogene lacustrine sediments rich in marl and calcareous clay, showed alkaline pH, moderate carbonate levels and elevated EC, reflecting a strong pedogenic influence from the carbonate-rich parent material. In contrast, the soils in Dolno Trogerci, formed by colluvial-alluvial deposits with contributions from volcanic and metamorphic rocks from the Vardar zone, showed greater textural variability and higher levels of CaCO₃ content. The semi-arid climate of the region, characterized by hot, dry summers and moderately cold winters, further shapes soil development and fertility. This study provides a basic understanding of the physicochemical and nutrient-related soil properties in the Ovche Pole Vine District and supports the development of site-specific sustainable vineyard management practices.
