The role of colloids on the bioavailability of phosphate to plants in highly weathered soils. KU Leuven
This Ph.D. addresses a concept that may lead to the development of a new type of phosphate (PO4) fertiliser. That fertiliser is based on nanoparticles of aluminium or iron oxides, coated with PO4. These nanoparticles act as mobile carriers of PO4 in soil, thereby avoiding that PO4-ions are trapped and fixed in soil minerals. Low phosphorus (P) availability is one of the most important plant nutritional problems in strongly weathered soils. ...
