Soil is what makes life possible on earth. It contains minerals, water, gases, and micro-organisms and forms the means for plant growth. The soil also serves as a storage of water and nutrients and has a filtering function. Soil can be strongly influenced by various factors such as climate, geology, and living organisms, both on a small and large scale. Because the soil plays such a large role in plant growth, the inclusion of soil products in the diet is essential.

Many of these soil functions are made possible by humus. Humus is a collective term for many complex organic compounds that can be roughly divided into fulvic acids, humic acids, and humins. These compounds have a negative charge and can therefore form complexes (chelates) with minerals and in this way regulate the concentration of nutrients in the soil. This ensures, among other things, that the soil has a purifying effect and can filter large metals from the atmosphere.

The Bio TKA Soil Products contain a large number of nutrients including fulvic acids, humic acids, and humins to improve the quality of the soil and to ensure an optimal yield. In this way, the organic-humatic nutrients are better for the plant and the climate.
