This study, focusing on the cultivation of wheat, consisted of applying an organic compound to the soil for a period of 2 years. The organic compound was made from a mixture of organic residues from a jelly industry (bovine chips and sharings) and other residues from a sugar-alcohol industry. The mixture was applied at random into the intergrowth lines in a top-dressing process, without incorporation, and in cumulative increasing doses. In the first year, the applications ranged from 2 to 25 t ha; in the second year, the applications ranged from 8 to 75, in wheat plants. Comparing the results of the chemical treatment to the organic application, it was observed that the organic compound increased the yield of wheat during the 2 years. Furthermore, the organic compound did not contaminate the plants, such as in the absorption of nutrients by the grains, once they have presented normal patterns of nutrient concentrations.
