Humusaineet
Humusaineet, also known as humic substances, are a complex mixture of organic compounds found in soil, peat, and other natural environments. They are the decomposed remains of plant and animal matter, transformed by microbial activity over long periods. Humusaineet are generally classified into three main fractions: humic acid, fulvic acid, and humin. Humic acid and fulvic acid are soluble in alkaline solutions, while humin is insoluble in both alkaline and acidic solutions.
These substances play a crucial role in soil health and plant growth. They improve soil structure by
Beyond their direct effects on soil and plants, humusaineet can also influence the environment by sorbing (adsorbing
