Humic substances can be described as naturally processed left overs (or litter) of plant and animal remnants which are stable to further degradation.

The unique biological features of humic substances is their high biocompatibility. The lack of toxicity, immunomodulating activity which stimulates stress resistance and growth in plants, as well as recalcitrance to biodegradation. Those features make humics extremely friendly to plants increasing crops and protecting from diseases. Of particular importance is that these are humics that retain water in soils, structuring it and deliver nutritional elements to plants. As such, humics serves as cornerstone of soil fertility.

The given friendly nature of humics is reflection of their chemical structure presented by a mixture of naturally oxidized organic molecules of mostly acidic nature. The presence of numerous oxygen containing groups and extended carbon skeleton provide for high surface activity of humics. The latter enables interactions with biological membranes and brings about the beneficial biological effects mentioned above. In addition, polyfunctional nature of humics provide for their ability to bind metals and hydrophobic compounds into stable and non-toxic complexes. This allows for their definition as natural detoxicants: this is because due to high molecular weights of humic macroligands, their complexes with contaminants become not bioavailable for plants.

The beneficial properties of humics can be enhanced through knowledge-based design of humicbased molecules.

Those "designer-humics" can possess properties which are not inherent within the natural HS expanding even more the field of possible applications of humics.
