Abstract :
Altitude have different soil chemical and physical properties are different as well. Chemical and physical properties of soil affect the amount of roots. This research looks at the relationship between the amount percentage of Arabica coffee roots Sigarar Utang with soil chemical and physical properties Inceptisol Lintong Nihuta on different altitude. Calculation of the amount of Sigarar Utang Arabica coffee roots were calculated using the distribution of root observation by Bohm. Chemical properties of the soil were observed in this study is pH H2O, C-organic, N-total, P-total, K-dd, and CEC, while the physical properties of soil texture and bulk density. The results showed that the percentage of Arabica coffee roots declines with distance from the lateral and vertical tree from the ground. Altitude does not significantly affect the number of roots. Chemical and physical properties that significantly affect the percentage of the root is C-organic, N-total, K-dd, CEC, and texture of the clay.
