The Relationship between WDPT and Soil Organic Matter
Abstract：Soil organic matter is the main factor of soul water repellency.This paper got the contour of Water Drop Penetration Time（WDPT） for three kinds of soils namely clay,loam and sandy soil,by measured WDPT in the field and soil moisture and organic matter in the lab.Meanwhile the relationship between WDPT and soil organic matter was got by measuring WDPT after drying soil samples 65 ℃ for clay and sandy soil in the lab.The results show that the relationship between WDPT and organic matter shows difference between soils.It is a power correlation for clay and sand and no linear correlation for loam.It can provide the theory for the factors of soil water repellency and soil amelioration.
