Devastated areas, which arise from situations such as open cast mining, landfill surfaces, road construction or former production facilities can and must be regenerated. That means they are returned to their earlier state or a different, natural state. The soils of these destroyed, desert-like landscapes are usually low in nutrients, sandy and contaminated with chemicals, heavy metals or oil. Geohumus, a water-storing soil additive, contributes to the resettlement of degraded surfaces.
Geohumus is mixed directly into the soil and absorbs the water that is normally lost through surface draining, leaching and evaporation. Geohumus expands like a sponge, storing up to 40 times its own weight in water and thereby significantly increases the water retention capacity for sandy soils, in particular. Plants can absorb the stored water through their roots as needed.
Geohumus stimulates the growth of plant roots. In Geohumus, plant roots find a favorable environment that is rich in water, oxygen and nutrients. This environment provides for optimal development of roots and increased root growth.
Along with the absorbed water, the nutrients released in it are also stored in the root area and can be used more efficiently as a result. The drainage of nutrients is also significantly reduced.
The expansion and shrinking during the absorption and release of water loosens the soil. Through the improvement of the soil structure, soil life and microbial activity are stimulated and the resupply of plant nutrients is promoted.
The combination of improved water supply, improved nutrient utilization, stimulation of the soil life and better root penetration ensure for a strengthening of plants. Depending on the plant type, more biomass emerges, more flowering occurs and the flowering time lasts longer.
With the use of Geohumus the mobility of the heavy metals contained in soil, such as zinc, copper and cadmium, is reduced.
Geohumus enhances the heat storage capacity of the soil and thereby protects the roots from freezing. Frost damage from temporary fluctuations in temperature near the freezing point is reduced with Geohumus.
This is the result of numerous toxicological and eco toxilogical reports. The water storage characteristics of Geohumus last for 3-5 years, depending on the soil type. Soil animals provide for the physical reduction of the Geohumus aggregate, whereas fungi and bacteria provide for the biological decomposition of the material.
