Soil fertility has become an interconnected aspect of modern agriculture, incorporating factors such as nutrient availability from soil, and its revision necessary for ensuring sustainability. Therefore, to understand the solubility nutrients organomineral fertilizers pelleted with biosolids sugarcane filter cake, evaluate resulting chemical changes in soil use, experiment was performed a completely randomized design. The done four replicates 3 × 5 +1 factorial scheme, using three fertilizer sources (mineral fertilizer, pelletized biosolids, cake); five doses (60%, 80%, 100%, 120%, 140% recommended dose fertilization corn); additional control treatment (absence fertilization). formulation 5-17-10 10% total organic carbon. All were packed microfiber cloth positioned 1 cm below surface incubated 60 days. Subsequent evaluation attributes: pH H2O (1:2.5); SMP (Shoemaker-McLean-Pratt); content exchangeable aluminum, phosphorus, potassium, calcium, magnesium, silica, matter within done. Organomineral or cake do not acidify but they found reduce aluminum saturation promote slow release nutrients, which allowed more balanced base soil. This then ensured better balance greater cation exchange capacity, sums, saturation. use these can contribute stabilizing fewer applications acidity correctives
