Abstract
Due to limits in global phosphate rock reserves for fertilizer use, it is vital to increase phosphorus fertilizer use efficiency (PFUE) to maintain agricultural productivity and food security. With 865 observations from 82 papers we investigated how PFUE in cereal crops was affected by climate (mean annual temperature), soil (pH, texture, available P), and management factors (crop type, fertilizer type and amount). We found that P content in aboveground biomass increased by 12.4% (95% confidence intervals 11.5–13.4%) of the P fertilizer applied across all observations. This PFUE was lower in maize than in rice and wheat, and was lowest in soil with near neutral pH. Our results indicate that there is much opportunity for improving PFUE in cereal crops.
期刊介绍：
Global Food Security plays a vital role in addressing food security challenges from local to global levels. To secure food systems, it emphasizes multifaceted actions considering technological, biophysical, institutional, economic, social, and political factors. The goal is to foster food systems that meet nutritional needs, preserve the environment, support livelihoods, tackle climate change, and diminish inequalities. This journal serves as a platform for researchers, policymakers, and practitioners to access and engage with recent, diverse research and perspectives on achieving sustainable food security globally. It aspires to be an internationally recognized resource presenting cutting-edge insights in an accessible manner to a broad audience.
