Influence of soil fertility management technologies on phosphorus fractions, sorption characteristics, and use efficiency in humic Nitisols of Upper Eastern Kenya

Most agricultural soils have ample total phosphorus (P) reserves but are very low in plant-available fractions for optimal productivity. This study gives insights into technologies, which increase the labile P concentrations and reduce the potential depletion of the non-renewable rock phosphate and the use of inorganic phosphatic fertilizers for agricultural production.
