Examples of Cevial triangles are the medial triangle and the orthic triangle.

Cevial三角形例子有中線三角形和垂足三角形。

160 Cm soil layers by soil drill and Nmin concentrations in the soil were measured by flow analysis after CaCl2 extraction. The results showed that NO3--N is the major inorganic nitrogen form in orthic anthrosol soil, and there are no significant differences in soil Nmin accumulation between sole cropping and faba bean/maize intercropping at the co-growth stage.

The increased amount of non--exchangeable NH4^＋-N during the incubation indicated as the following tendency, namely, Eum-Orthic Anthrosols 〉 Los - Orthic Entisols 〉 Hap-Ustic Isohumisols 〉 Ust-Sandiic Entisols. Organic material influenced significantly the increased amount of non-exchangeable NH4^＋-N （P was 0.0002, 0.0004 and 0.0003 when incubated at 20 d, 50 d and 60 d, respectively）. NH4^＋-N increased remarkably when Stlpa bungeana and Medicago sativa were added compared with no addition. The contents of non-exchangeable NH4^＋-N increased significantly when added （NH4）2SO4 compared without addition at 20 d, 40 d and 60d of incubation and P was 0.0037, 0.0033 and 0.0027, respectively. It was the result that the NH4^＋-N from （NH4）2 SO4 was fixed within the soil. The increased amount of non-exchangeable NH4^＋-N increased significantly for different soils, on which different vegetation types grew before the collection of soil samples, when incubated at 20 d （P=0.0434）, but not significantly at 40 d and 60d （P=0.7378 and 0.5375）. The increased amount of non-exchangeable NH4^＋-N in the soil, on which crop straw and nitrogen fertilizer had been incorporated for a long-term period, was larger than that of no addition, but it was not significantly different among these two fertilization models. Soil clay, total N and organic matter were positively correlated remarkably with the contents of non-exchangeable NH4^＋-N, the increased amount of non-exchangeable NH4^＋-N had no correlation with soil clay, whereas it had significantly positive correlation with total N and organic matter.

The placement of 11 taxa, formerly sorted on the subgroup level of the Chinese Soil Genetic Classification System, in CST was elucidated in the paper. All these soils studieds are classified into 5 CST Orders: Anthrosols, Ferrosols, Argosols, Cambosols and Primosols, 5 CST Suborders: Stagnic Anthrosols, Udic Ferrosols, Udic Argosols, Udic Cambosols and Orthic Primosols, 15 CST Group and 23 CST Subgroups.
