| Abstract: | Active nutrient in Shanxi calcareous soil was extracted with Mehlich3. Compared with the routine method and relative research, the results showed that the results of macroelements and Microelement in soil which are analysised by Mehlich3 method were significant or remarkable correlative with the results of routine method. On this basic, we formulated the grade standards of Mehlich3 for testing macroelement and microelement in Shanxi calcareous soil. M3 can be used to test P, K, Mg, Na, Cu, Zn, Fe, Mn in Shanxi calcareous soil. |
