Abstract:: Taking Maca as test material，the effect of the contents of rapidly available nitrogen,phosphorus and potassium and pH value in soil by planting Maca were studied.Took samples from the soil not planting Maca and the soil planting Maca each at the altitude of 2 700 meters,2 850 meters,2 950 meters and 3 150 meters in Lijiang Maca area,and determinated the contents of rapidly available nitrogen,phosphorus and potassium and pH value of each sample.The results showed that after planting Maca,the contents of rapidly available N and K in the soil reduced;the content of rapidly available P in the soil increased and pH value of the soil reduced in some area.
