Abstract
The present disclosure discloses a method for targeted regulation of soil microbes to synchronize heavy metal/metalloid transformation and greenhouse gas emission reduction and use. The present disclosure discovers that by compounding methionine with an organic acid salt, the obtained formulation can significantly increase the ability of the soil microbes to promote arsenic methylation in a targeted mode, and meanwhile, and the methane production is effectively reduced in the presence of the methionine. In the present disclosure, the methionine/organic acid salt formulation is further loaded into a modified biochar material of a porous structure, so as to achieve the effect of slow release. The method of the present disclosure may effectively reduce absorption of inorganic arsenic by rice, achieve a significant reduction in the proportion of inorganic arsenic in the total arsenic in the rice and inhibit methane emission of the soils and reduce methane emission at the same time.
