Conteúdo: 	Here, we propose a mechanochemical route to manage the disposal of asbestos fibers material from raw chrysotile and asbestos cement, using it as a nutrient source for agriculture. The mechanochemical process, using citric acid as a reactant, led to the fibers? disruption. The constant mixing, the reactants? friction, and the ion migration enabled the formation of calcium/magnesium citrates. Through soil incubation and enzymatic profile analyses, we showed the beneficial effect of these products as readily available carbon to stimulate endogenous microbiota, releasing Ca2+/Mg2+ to correct acid soil pH. The results evidence the potential of these citrates to promote an acidic buffer to the soil and, after their microbiological decomposition, their equivalent effect to commercial limestone for soil pH correction.
