Title: A new perspective on the efficiency of phosphorus fertilizer use
Abstract: It is commonly believed that the efficiency of phosphorus (P) fertilizer use is low--of the order of 10-25%. When efficiency is assessed using the ‘balance’ method, which takes into account the recovery of P added in previous applications and when an adequate time period is considered, the efficiency of P use is high—up to and sometimes in excess of 80%. It is possible to establish a ‘critical’ level of P for a given soil and farming system and at this level the efficiency of use is at or close to 100%. The objective should be to reach and maintain this critical level to optimize P-use efficiency.
