Research has shown that the chemical properties of soil in the study may model pH KCl in the year are in the form of acid ranged from 3.01 to 4.32, increasing humus content and are at average or better, ranging from 2.14 percent to 4.43 percent. Nitrogen total are medium to good level ranged from 0.15 percent to 0.37 percent. Potassium available and Plutonium available are poor to moderate levels ranged from 13.07 ppm, respectively, to 27.03 ppm and 21.12 ppm to 36.24 ppm. General chemical soil is highly variable and is a good way to improve gradually over the years. However, this is only the initial results of research on soil quality changes under different forest model should be studied further in the coming years.
