Organic humic acid is a fertilizer that feeds plants the way nature intended. Unlike nitrogen and phosphorus, which burn out quickly and need to be continually replenished, humic acid stays active in the soil for years. Humic acid boosts nutrient uptake and root growth, while also improving soil structure, preventing compaction and erosion. It can even help plants withstand drought and heat stress
