Soil properties vary spatially at all level of observation within a field to a larger regional scale and the causes of the variation can be both natural and anthropogenic factors. Knowledge of spatial variability in soil properties is important for effective nutrient management plan in crop production. One integrated test by compiling several soil properties together may provide growers with one number that represents as overall spatial variabilities. Therefore, understanding the functional relationship between soil properties is necessary. The objective of the study was to characterize a soil indicator that can be used to estimate the overall spatial variability of selected soil properties in orchard farming systems. We have selected and analyzed eight soil chemical parameters, including pH, EC, SOC, available N, available P, and exchangeable cations such as K, Ca, and Mg of the individual 126 soil samples collected randomly from 42 orchard farms across Chungcheong province. The median of each soil parameters was similar or lower than the mean, which indicates that the effects of abnormality on sampling value were not high. Coefficient of variation (CV) indicated that soil parame ... 전체 초록 보기
