Study on Vertical Change Regularities of Physical Properties of Water in Typical Black Soil
CHEN Min et al (Northeast Forestry University,Harbin,Heilongjiang 150040)
The physical properties of water in typical black soil were measured and analyzed. The results showed that the soil bulk density showed increasing trend with the increase of soil depth. Soil porosity was decreased with the increase of soil depth. The whole soil layers could be divided into high porosity zone of 0-50 cm and low porosity zone of 50-100 cm. Soil water holding capacity was decreased with the increase of soil depth.
