Abstract

Infiltration is the movement of water through the soil. These is one of hidrologycal cycles. Infiltrate which annoyed at one area will influence the cycle hidrology on that area. So, management of soil is important to keep the equilibrium of the cycles. Beside that, it is important to use as plant which will give forest productivity. Forest productivity can be conducted with ground quality and availibility of ground water through infiltrateing. Soil phisic is a number of factors impact soil infiltration. They are, bulk density, porosity, permeability, soil water content, ect. Infiltration measured by double ring infiltrometer and soil sample have taken by method not disturbed. Then, soil sample were collected analysed on soil Laboratory of Agriculture Faculty. Regretion have made between soil phisic and infiltration. Regretion also have made between infiltration and stand density. Result showed that infiltration have strong relation with soil phisic. But, infiltration does not have relation with stand density. Infiltration also influences by organic matter, tillage, open cwron, temperature and topography.
