Humic substances
Humic substances are complex organic materials formed from the decay of plant and animal matter in soils, peat, and natural waters. They include humic acids, fulvic acids, and humin, which contribute to soil fertility by improving nutrient retention, water holding capacity, and soil structure. These substances act as natural chelators, helping plants absorb essential minerals more efficiently. They also influence soil pH and stimulate microbial activity, supporting healthy ecosystems. Humic substances are key components in organic farming and soil health management, playing a vital role in sustainable agriculture and environmental quality.
