Humic substances are effective in the suppression of delayed type hypersensitivity, rat paw oedema, a graft-versus-host reaction and contact hypersensitivity in rats. They reduce the C-reactive protein levels of patients suffering from osteoarthritis of the knee and the wheel and flare reaction of patients suffering from hay fever.

Commercial humic fertilizers (humates) can be used to improve carbon sequestration. In this study, a 3-year field trial (2016–2018) employed four treatments investigate the mechanism by which humate increases sequestration in fluvo-aquic soils: (1) blank: bare soil with no agricultural treatment; (2) control: standard film mulch (FM) ridge-furrow tillage (which acts as CK); (3) humate: FM plus ...
