This study investigates the hypothesis that enhancing early plant growth can lead to a more efficient utilization of phosphorus (P) from both indigenous soil resources and P fertilizers. Phosphorus availability is a limiting factor for crop production globally, and substantial amounts of mineral P fertilizer are applied to sustain food production. However, the efficiency of P fertilizer use remains low, with considerable losses throughout the production chain. Furthermore, excessive P application can lead to P accumulation in soils. As P resources are finite, improving plant uptake ability becomes crucial. This report focuses on analyzing the impact of early root growth on enhancing plant P uptake, irrespective of soil P levels.
