Abstract:

Based on the soil geochemical survey in Xinmin-Lierbao area, we collected 574 soil samples for geochemical analysis and testing. The pH values and nutrient indicators,such as organic matter, nitrogen (N), phosphorus (P), potassium (K), sulfur (S),water soluble calcium (Ca) and magnesium (Mg), were discussed. The study area mainly belongs to alkaline-strong alkaline, rich K, medium rich P, poor N soil, S exceeding in some areas. In the comprehensively researched evaluation, there are first and second rich levels accounting for 31.99%, the middle rich levels accounting for 43.8%, the low-middle rich levels accounting for 24.07% and the poor levels accounting for 0.15% in the study area. The results provide reference for soil improvement and high efficiency in the study area.

Key words: soil geochemical characteristic, soil nutrient, Xinmin-Lierbao area, Minhe County,QinghaiProvince
