Agronomic Performance of Mineral and Organic Sources of Nutrients for Maize and Wheat Crops
A combination of mineral and organic source of nutrients was tested in a field experiment, aiming to evaluate its effects on soil chemistry and on maize and wheat productivity. Data showed clearly the potential for the use of shale limestone as a source of Ca, Mg and S, Granodiorite as a source of K and Tung press cake residue as a source of N.
