Soil bulk density is a fundamental physical properties of soil, soil permeability, air permeability, infiltration performance, water-holding properties, solute transport characteristics and the ability of soil erosion has a very big impact. Under natural conditions, soil bulk density as soil parent

Soil bearing capacity is one of the fundamental physical properties of soil, the soil permeability, ventilative, into the seepage performance, water features, when a solute migration characteristics as well as the Soil erosion-resistant ability of all have a very big impact. Under natural conditions

The soil bulk specific gravity is a soil basic physical property, to the soil water permeability, the permeability, enters infiltrates the performance, the water retention property can, the solute migration characteristic as well as soil anti-etching power all has the extremely tremendous influence.

Soil bulk density is a fundamental physical properties of soil, soil permeability, permeability and infiltration, water-holding capacity, solute migration characteristics and soil erosion resistance have a very big impact. Under natural conditions of soil bulk density due to Cheng Tumu mass, ustrope
