Soil as a specific type of porous media known as a capillary porous medium is described, and its basic physical properties are defined. Because soil is a three-phase system, composed of solid, liquid and gaseous components, the basic properties of all three phases are described and quantified....
Analysis of physical-chemical properties including structure of profile,pH,soil texture,soil organic matter,the concentration of heavy metals of the soils were conducted. The results indicated that the source of the parent material of the road area soils was complicated and the soil profiles were ...

The soil ulmin is appraises the soil fertility quality an important target, is related with many kinds of soil nutrient, simultaneously holds water physical properties and so on water furnishing ability, porosity and coacervate to the soil has important influence [15].It is in the soil various...
the main composition of the three agricultural humic-acid-containing fertilizers is humin,whose content can reach 77.3%~93.7%,and the content of fulvic acid is less than 1%;the properties of A and B are similar in bulk density,pH value(pH7),cation exchange capacity and content of ...
Increasing basic farmland soil productivity has significance in reducing fertilizer application and maintaining high yield of crops. In this study, we defined that the basic soil productivity (BSP) is the production capacity of a farmland soil with its own physical and chemical properties for a speci...
