Plant-available soil phosphorus (P) is commonly assessed by chemical extractions with the purpose of diagnosing and advising fertilizer P application. However, for a given crop, this approach only poorly predicts yields obtained from several experimental sites. To solve this major drawback, a functional and mechanistic evaluation has been developed to mimic dominant processes involved in the absorption of phosphate ions.

植物可溶土壤磷的功能和机理评估大大提高了玉米产量响应的多站点诊断


植物可溶土壤磷 （P） 通常通过化学提取进行评估，目的是诊断和建议肥料 P 的施用。然而，对于给定的作物，这种方法只能很好地预测从几个实验地点获得的产量。为了解决这一主要缺点，已经开发了一种功能和机理评估来模拟参与磷酸根离子吸收的主要过程。
