Conteúdo:	Brazil is the second-largest producer of chicken meat globally, generating substantial amounts of manure with potential environmental impacts if inadequately managed. Dehydrated chicken manure can be a technique used to reduce volume, lower emissions, and increases shelf life however, its fertilization efficiency can be lower than that of mineral fertilizers. This study aimed to develop organomineral fertilizers combining dehydrated manure with mineral nutrients and to evaluate their effectiveness in supplying potassium (K) relative to KCl and K2SO 4. Five NPK formulations were applied to nutrient-poor sandy soil in a greenhouse experiment using corn as an indicator crop. The aboveground biomass was harvested, dried, and weighed to assess dry matter production and agronomic efficiency. All fertilized treatments enhanced growth compared to the control. T1 achieved the highest dry matter (6.48 g·pot ¹) and agronomic efficiency (49.40%), followed by T5 (5.89 g·pot ¹, 43.48%), whereas T3 exhibited the lowest efficiency (10.78%). The results indicate that the organomineral formulations can viable alternatives in supplying K to corn.
