Abstract
The Study of chemical characteristics and soil physics under tree stands Camphor (Dryobalanops aromatica Colebr) aims to evaluate the chemical and physical properties of the soil in influencing the growth and production of trees Camphor (Dryobalanops aromatica Colebr). This research was conducted at the Research and Technology Laboratory Faculty of Agriculture University of North Sumatera, The research was conducted from November 2017 to March 2018. The research used a survey method with sampling based on purposive sampling that is taking soil samples. The results showed that the characteristics of the land under lime stands varied considerably, is cation exchange capacity (low and very low), C-organic (low, medium, and high), soil texture (sandy clay and sand clay), pH (very acid ), and Ca-total (very low). The result of regression analysis showed that the real soil organic matter is directly proportional to the height and diameter of the lime tree trunk, while the real soil pH is inversely proportional to the height and diameter of tree trunks and the real exchange rates are directly proportional to plant height but not significant to the diameter of the stem.
