ABSTRACT
Phosphorus (P) is an essential macronutrient in biological organisms. Optimizing P use efciency will deliver agronomic, economic, and environmental benets as agricultural production systems adjust to meet future global food production targets (Heffer and Prud’homme 2013). Such an optimization will rely on adequate knowledge of the dynamics of soil P pools to enable accurate predictions of the required external P inputs to achieve optimum growth of subsequent crops (Damon et al. 2014).
