Abstract

                                Optimum fertilizer application to soil is one of the well-established methods for increasing crop production. But the require- nents of nutrients differ considerably for different crops and for the same crop on different soil types. Phosphorus influences plant growth and yield markedly. With the recent trends in producing high yields using nitrogenous fertilizers, crop removal of all nutrient elements, including phosphorus, increases considerably, and consequently the need arises for making substantial phosphorus applications. Phosphorus availability in individual soils by employing different phosphate carriers, was therefore investigated.
