Mechanochemical Activation of Elemental Sulfur Increases Its Bioavailability in the Forage Species Brachiaria Production
Although sulfur is an essential macronutrient for plants, its supply through elemental S0 is not efficient, demanding its oxidation by soil microbiota before plant uptake. Thus, we demonstrate that a simple reactive mechanochemical route, using anhydrous KOH as a reactant with no need for water addi...

Although sulfur is an essential macronutrient for plants, its supply through elemental S0 is not efficient, demanding its oxidation by soil microbiota before plant uptake. Thus, we demonstrate that a simple reactive mechanochemical route, using anhydrous KOH as a reactant with no need for water addition, can convert S0 to bio-absorbable oxidized forms, leading the residual K+ a plant nutrient in the final composition. The powdery products obtained by 1 h (S-1h) or 8 h (S-8h) milling have been fully converted to HSO3-, SO32-, and SO42-, also suggesting different amounts of these sulfur oxides according to the milling. S-1h and S-8h were efficient for S and K fertilization, probed on the successful growing of the forage crop Brachiaria ssp. in a greenhouse trial, with similar biomass yields observed for K2SO4 (positive control) and superior to S0 + KCl (negative control). These data suggest that the mechanochemical process provides a sustainable route to increase sulfur plant bioavailability, suggesting a simple alternative that can be easily implemented in forage plant production sites such as Brachiaria ssp. |
