dc.description.abstract | Phosphorus (P) is known as one of the essential macroelements for all life, is as important as Nitrogen (N) and Potassium (K) for as a fertilizer component, and unfortunately, is a limited, nonrenewable natural resource, which makes it extremely important to secure efficient utilization as a plant nutrient. When P-fertilizers are applied to soil, strong binding of phosphate can occur, particularly in acid soils. This fixation of fertilizer-P in the soil matrix limits the uptake of fertilizer P by the growing crops, leading to a low recovery of fertilizer P in the harvest. Fixed P is accumulating in soil as more P-fertilizer applied, and this phosphate is so tightly bound to the soil that crops can only take up a minor fraction of it. In this thesis, a conceptual novel P-fertilizer was presented as a hypothetical solution to this P-fixation problem. | en_US |
