Description:
Based on 23 years of data, yields of maize, wheat and cotton were modelled under different fertilizer management practices and at different levels of available phosphorus (Olsen-P) in soil. Three types of threshold models were used, namely linear-linear (LL), linear- plateau (LP), and Mitscherlich type exponential (Exp). The agronomic thresholds of available phosphorus were 25.4 mgkg -1 for cotton, 14.8 mgkg -1 for wheat, 13.1 mgkg -1 for maize and 25.4 mgkg -1 for the grey desert soil regions of Xinjiang in China as a whole.
