Humic products have been utilized for many years in turf and landscape applications as natural chelators, soil conditioners, and nutrient enhancers. Humic products are typically used in turf management to help retain soil moisture, stabilize nutrients, and to increase nutrient efficiency. Because of their effects on soil microbial activity, some of indirect effects of humic substances are:
- Increase soil aeration
- Positive impact on soil structure
- Improved drainage
Humic substances are complex long chain carbon materials that interact with nutrients, soil colloids and microbes in soil-plant root zone, called the rhizosphere. They primarily influence micronutrient interactions and soil health, which are essential to plant root development and plant health. The chemically active fractions of humic substances are called Humic and Fulvic acids.
