Conteúdo: 	The objective of this work was to evaluate the efficiency of granulated fertilizers based on potassium chloride with humic acids in the production of dry matter and the accumulation of macronutrients in corn plants. The experiment was carried out in a greenhouse, using soil samples from the 0-20 cm depth layer of a Planossoloháplico. A completely randomized block design was adopted, in a 2 x 5 + 1 factorial scheme with two sources of humic acid extraction (vermicompost and peat), five concentrations of humic acids in the granulations (0; 2.5; 5.0; 7.5 and 10.0%) and one additional treatment that consisted of the application of commercial potassium chloride, with three replications. The plants were collected at sixty days after sowing. There was a slight difference in the production of the dry root mass. The P accumulation presented the most pronounced differences, whereas the granulated potassium chloride with humic acid extracted from vermicompost showed the best performance.
