Humic Acid Ore 45%
100% naturally derived, mined Leonardite is perhaps the richest unprocessed source of humic acid. A valuable soil additive, humic acid improves depleted soil conditions by replacing and compensating for carbon and mineral loss, and by stimulating microbial life and activity. It also increases the effectiveness of fertilizers, which in turn reduces the need for nitrogen supplementation by up to 50%. For lawns: 1 1/2 pounds per 100 square feet. Vegetables, beds and ground covers: 15 pounds per 100 square feet.
