Humic acids are mainly found in nutrient-rich, slightly acidic to neutral soils. They belong to the humic substances. Humic substances are formed from fragments and residues that are difficult to convert, such as spruce needles. They form organic-mineral complexes that contribute to structural stability and are very rich in nutrients. However, the nutrients are only released during decomposition.
