Reassessing the value of phosphorous replacement strategies on fixing soils

To quantify the economic benefit to farmers of:applying high application rates of phosphorus (P) on moderate buffering soils (phosphorus buffering index PBI) across a range of sites with different yield potentials, andcomparing three-four common wheat and barley varieties to assess their Phosphorus Use Efficiency (PUE).本数据集旨在量化农户可获得的种植经济效益，研究涵盖两项核心内容：其一，在一系列具备不同产量潜力的试验点位中，针对中等缓冲能力土壤（磷缓冲指数，phosphorus buffering index, PBI）施用高用量磷（P）肥；其二，选取三至四个常见小麦与大麦品种，评估其磷利用效率（Phosphorus Use Efficiency, PUE）。
