Comparison of Soil Chemical and Physical Properties in Anysoil and Sand-Based Soil Systems
2021
Kim, K.N.
This study was conducted to compare soil chemical and physical properties under anysoil and sand-based soil systems and to provide basic information on turf design, construction and maintenance. Soil acidity, electric conductivity, soil texture, soil porosity, and moisture content were analyzed. Significant differences were observed for these parameters. From analysis on soil texture, California system was classified as sand, while anysoil system as loamy sand. Soil porosity for California and anysoil systems was 45.0% and 52.0%, respectively, being 7.0% in differences. Moisture content ranged from 12.0 to 24.0%, being twice greater under anysoil system for water retention capacity than under California soil system due to higher micropore percentage. Soil acidity ranged between 5.90 and 6.00, being no significant differences in soil systems. Electrical conductivity in anysoil and California systems, however, was 32.20 and 50.35 μS cm⁻¹, respectively, being 56.3% higher in California system than in anysoil system. Considering both soil chemical and physical properties, a sand-based California system was better for turfgrass quality than anysoil system of loamy soil. Clay content was approximately 130 times greater under anysoil system than under California system. This led to higher soil moisture content, but lower drainage capacity, as compared with a sand-based California system. Accordingly, it should be improved by mixing sand to increase macropore content in rootzone layer when turf establishment and maintenance in loamy soil of anysoil system. From this study information on soil chemical and physical properties under both soil systems would be practically useful in turf design, construction and management.
