This paper presents the short-term effects of the application of four types of ground rock and tung cake on the quantity of accumulated nutrients in the dry matter of the aerial parts of com. The limestone shale proved to be a source of rapid release of Ca and Mg, with an equivalent or superior effect to commercial dolomitic limestone used as a reference for this study. The tung cake showed performance equal to or better than that found in fertilizer with conventional sources of high solubility NPK.
