The Andersons HumiChar Organic Soil Amendment

HumiChar is the soil amendment that changes how your soil functions at a fundamental level. It combines two powerful inputs: humic acid, which improves nutrient uptake efficiency and feeds beneficial soil bacteria, and biochar, a carbon-rich material that creates permanent micropores in the soil that retain water, nutrients, and microbial habitat. Unlike lime or gypsum that correct specific problems, HumiChar improves overall soil quality — particularly important for fill soil, sandy soil, and degraded lawns that lack organic matter and biological activity. The Andersons' Dispersible Granule (DG) technology means the granules disintegrate on contact with water, releasing the humic acid and biochar as micro-particles that penetrate deeply without tilling. Biochar persists in soil for decades, meaning this is one of those investments that keeps paying off. At 12,000 sq ft per 12-lb bag, it's extremely cost-effective. The 4.7-star Amazon rating with 3,800+ reviews from lawn enthusiasts speaks for itself — this is the product people come back to season after season.
