The Yeongcheon region in Gyeongbuk Province is actively engaged in grape cultivation, particularly focusing on Shine Muscat varieties. Recently, various cultivation structure types including wide-roof vinyl shelters and greenhouses have been introduced alongside conventional vinyl shelters. These different structural systems not only affect crop growth environments but also significantly influence soil chemical and physical properties, including nutrient accumulation and effective plowing depth. However, systematic research on the relationship between cultivation structure types and soil chemical-physical properties remains limited.
This study investigated 44 representative vineyard plots over the periods of 2021 and 2024, measuring soil pH, electrical conductivity (EC), organic matter content, available phosphate (Av. P₂O₅), exchangeable cations (K⁺, Ca²⁺, Mg²⁺, effective plowing depth, and soil profiles to elucidate the interactive effects of cultivation structure types on soil physicochemical properties.
Significant differences in soil chemical and physical characteristics were observed between the two cultivation structure types. While pH and EC showed no substantial differences between cultivation types, wide-roof vinyl shelters exhibited relatively higher organic matter and available phosphate contents compared to conventional vinyl shelters. Analysis of exchangeable cations revealed that K⁺ and Mg²⁺ concentrations were higher in wide-roof vinyl shelters, whereas Ca²⁺ concentrations were higher in conventional vinyl shelters. Furthermore, investigations of effective plowing depth and soil profiles demonstrated that wide-roof vinyl shelters showed deeper plowing depths and more developed boundaries between A and B soil horizons compared to conventional vinyl shelters.
These results demonstrate the fundamental differences in soil chemical-physical properties according to cultivation structure types, suggesting the necessity for customized soil management strategies tailored to specific facility types for sustainable grape production in Yeongcheon vineyards. Furthermore, this research is expected to serve as important foundational data for soil environmental conservation and productivity improvement in grape cultivation areas in response to the introduction of diverse cultivation facilities.
