Pedology pp Cite as. It has to classify the higher units, to group the major soil types of the world according to the genesis of their basic properties and thus provide a framework, of some kind, to act as a basis for the science of pedology;. It has to provide a means of making large-scale maps for practical purposes, such as in agronomy, which often necessitates the use of detailed characteristics, that are of local importance only, in defining and naming units. It is obvious that this classification of lower units involves entirely different problems from that involved in dealing with the higher units. Unable to display preview.

Based on the characteristics of Lycoris aurea L. We found that there existed significant differences in the contents of mineral elements and the activities of soil enzymes urease, phosphatase, sucrase and catalase etc. Among which, the contents of organic matters, alkali-hydrolysable nitrogen, Ca and Mg as well as the activities of soil enzymes in humus soil were the highest ones.

In the United States Department of Agriculture , textural classification triangle , the only soil that is not predominantly sand, silt, or clay is called "loam".
