BioHumate Improves soil conditions and mycorrhizae levels BioHumate is a liquid blend of biologically active ingredients derived from seaweed extract and humic acid which, when combined, exert a positive effect on the whole growth cycle of arable and horticultural crops. It improves soil conditions, and, in particular, promotes the activity of beneficial bacteria and fungi including mycorrhizae. This leads to an improved soil structure and encourages the symbiotic relationship between plants and their associated microbial species Information sheet
