Abstract

The work evaluates the solubility of a soil remineralizer based on the K contents extracted in H2O, Mehlich-1 and 2% Citric Acid, and its effects on the fertility parameters of a Quartzarenic Neosol. The evaluated soil remineralizer comes from a gemstone mining company located in the city of Pindorama, State of Tocantins, whose composition has 4.5% K2O, in addition to other plant nutrition elements, and granulometry 100% < 0 .8 mm. In the evaluation of the effects on soil fertility, increasing doses of K corresponding to those recommended for the most diverse agricultural crops were used (100 to 400 kg ha-1 of K), while the solubility evaluation considered the remineralizer exclusively (100%) and its mixture with the soil in different proportions (0%, 50% and 75%). The results show that the 2% citric acid solution is more efficient in K extraction, being a fast method to determine K contents for cultivated plants. The remineralizer had a significant effect on several physicochemical parameters of the soil, including the K content, with important significance for agricultural management.
