The relationship between concentration of elements and plant growth and human health depends upon available forms of element in soils. While the factors affecting element availability are soil pH and Eh, tillage and fertilization by man besides element forms in soils. On the basis of pedogeochemical types and distribution, rational plantation and application of fertilizer to soils will be of great significance for sustainable development of agricultural production.展开更多

Based on analytical data, the weathering or soil forming processes fall into four stages and China is divided into four geochemical regions: saline soil region, carbonate soil region, siallitic soil region and ferrallitic soil region. Moreover, some endemic diseases in relation to the deficit or excess of some elements are discussed in the viewpoint of pedogeochemistry.展开更多
