The control, NK, NP, PK, NPK, OM and 1/2OMN treatments were indicated by white, red, yellow, blue, green, black, and purple circles, respectively. Environmental variables were shown by arrow lines. The percentage of explanation variation is shown in each axis, and the relationship is significant (P = 0.005).
