Abstract

This study assessed how different hill slope positions under uniform management practice within a Khasi mandarin orchard (Citrus reticulata Blanco) influence biological pools of carbon (C), nitrogen (N), and phosphorus (P), and soil quality. The orchard soils (0 to 15 and 15 to 30 cm depths) of summit, shoulder and backslope hill slopes were analysed during post-monsoon (October–November) at fruit ripening and post-winter (March–April) at flower initiation. Principal component analysis revealed that hill slope position and soil moisture had significant influence on variability of soil biological pools. Sizes of biological pools were significantly higher in post-monsoon than post-winter. It is highlighted that hill slope position and soil moisture had coupled control on spatio-temporal variability in soil biochemical attributes within an orchard in spite of uniform orchard management practice
