Full Description
This collection features four peer-reviewed reviews on phosphorus uptake and use in crops.
The first chapter summarises the progress in research on root traits associated with phosphorus acquisition, including root morphology, architecture, biochemistry, colonisation by arbuscular mycorrhizal fungi, and fine root endophytes. The chapter also reviews the recent advances in breeding programmes to improve phosphorus acquisition efficiency.
The second chapter discusses interactions between phosphorus management (phosphorus rate, source timing, and placement) and diverse cropping systems and climate and how these interactions are essential to efficient utilization of phosphorus resources.
The third chapter assesses the key soil, root and microbial processes that influence phosphorus acquisition with a focus on factors that can be managed to ensure optimal use of fertiliser and development of root systems for improved phosphorus acquisition. A case study from Australia is used to demonstrate how phosphorus efficiency of grasslands can be improved.
The final chapter reviews the environmental effects of phosphorus fertilisation in agriculture, primarily its impact on water quality. The chapter considers how future water quality issues can be mitigated and also examines the cycling, fate and transport of phosphorus in agriculture.
