Biologic Systems Granular Humate is a premium organic soil conditioner with 45% humic acid. Humic acids are essential components of soil that bind to nutrients and other organic compounds, unlocking unavailable nutrients, lowering the salt content and creating the aggregates necessary for proper soil structure. The unusually high carbon content in Biologic Systems Granular Humate encourages balanced carbon-to-nitrogen ratios necessary for maintaining healthy soil, similar to the primary benefit of BioChar. This granular soil conditioner is great to amend and renew soil, to mix into soil blends, and to top dress established plants.
