Liquid humate products, extracted from soft coal materials, typically contain 4% to 18% humic acid and can be applied both to soil and foliage. These products are versatile, offering immediate bioavailability for rapid plant response. In contrast, dry products, including micronized coal mixed with potassium hydroxide, are primarily for soil use and provide longer-term benefits over multiple growing seasons. The smaller the particle size, the higher the bioavailability. Choosing between liquid or dry products depends on whether you need fast results or sustained, long-term soil improvement.
