Earlier studies that drew on large soil profile databases have indicated that it is not (yet) feasible to present meaningful values for \u201cplant-available\u201d soil P, obtained according to comparable analytical methods, that may be linked to soil geographical databases derived from 1:5 million scale FAO Digital Soil Map of the World, such as the 5 x 5 arc-minute version of the ISRIC-WISE database. Therefore, an alternative solution for studying possible crop responses to fertilizer-P applied to soils, at a broad scale, was sought. The approach described in this report considers the inherent capacity of soils to retain phosphorus (P retention), in various forms. Main controlling factors of P retention processes, at the broad scale under consideration, are considered to be pH, soil mineralogy, and clay content. First, derived values for these properties were used to rate the inferred capacity for P retention of the component soil units of each map unit (or grid cell) using four classes (i.e., Low, Moderate, High, and Very High). Subsequently, the overall soil phosphorus retention potential was assessed for each mapping unit, taking into account the P-ratings and relative proportion of each component soil unit. Each P retention class has been assigned to a likely fertilizer P recovery fraction, derived from the literature, thereby permitting spatially more detailed, integrated model-based studies of environmental sustainability and agricultural production at the global and continental level (< 1:5 million). Nonetheless, uncertainties remain high; the present analysis provides an approximation of world soil phosphorus retention potential.", "formats": ["WWW:DOWNLOAD-1.0-ftp--download", "WWW:LINK-1.0-http--related", "canonical"], "keywords": ["Global", "soil", "soil chemicophysical properties", " soil fertility", " soil water conservation", "phosphorus", "nutrients", "Soil science", "Global"], "providers": [{"name": "Ulan Turdukulov", "organization": "ISRIC -
