The first three axes are drawn and the percent of variance explained by each axis is given. Treatment: (triangle) CK, no fertilizer; (circle) M, manure; (square) NPK, inorganic phosphorus, potassium and nitrogen fertilizer; (star) MNPK, inorganic P, K and N fertilizer plus manureBack to article page
