In many regions rainwater seeps through sandy soil into the groundwater, which is hardly beneficial to the plants. In such areas, Geohumus improves the water retention of the soil, which not only saves water but also increases yields since the plants are continuously supplied with water. In the home and garden, Geohumus is ideal for many types of seedlings and potted plants, garden patches and newly seeded lawns. In horticulture and landscaping Geohumus is especially useful where there is either insufficient subsoil for water retention (noise control walls, roundabouts or greenroofs, for example) or where the water retention capacity is very low (for example on golf courses or trackbeds) and a balance has to be established between drainage and water retention. Special cultures such as asparagus and strawberries likewise benefit from the properties of Geohumus. Higher yields and earlier harvests are the immediate advantages for the farmer. In subsidized projects Geohumus is already being used today for desiccation and for preventing expansion of desert areas, as well as for reforestation of barren land. |

Geohumus is a novel soil additive with the special ability to store water and make it available to plants.
Superabsorbers have already been used for a long time in the hygiene industry, especially for baby nappies, and are capable of storing large quantities of water. The mineral contents from volcanic rock flour, clay minerals and silicates supply important nutrient elements and at the same time provide for the structural stability of the granulate in soil.
Unlike conventional, mixed granulates, these components in Geohumus are inseparably combined. The porous, spongy, earth-like granulate forms a new class of material which stores water, thus making it available to plants. Geohumus can store at least 40 times its own weight in water, releases it back to the roots as needed, and, with the minerals contained in the flour rock, it provides for sustainable improvement of the soil quality. |

The characteristics of Geohumus are listed in detail in the following:
- More efficient water utilisation: Losses from leaching and evaporation are reduced, and irrigation intervals are extended considerably as a result.
- Nutrient supplier: With the rock flour contained in Geohumus the plants are provided with important minerals.
- Mechanical soil improvement: Geohumus improves the soil structure and ventilation through the expansion and shrinking of the granulate during the absorption and release of water.
- Reduction of fertiliser and pesticide requirement and groundwater protection: Geohumus reduces the leaching and drainage of fertilisers and pesticides. The use of fertilisers and pesticides and their drainage into the groundwater can be reduced as a result. Through a reduced drainage, nutrients and plant protectants are retained in the topsoil and prevented from migrating into deeper soil layers.
- Immobilisation of heavy metals: It has been verified in very recent studies that Geohumus immobilises heavy metals in contaminated soils.
- Heat balance: Geohumus increases the heat storage capacity of the soil and the immediate vicinity along with it. As a result, frost damage from temperature fluctuations near the freezing point are buffered.
- Harmless to health and environment: Numerous tests have proven that Geohumus is non-toxic and therefore safe for the environment. The soil additive is physically broken up by mechanical treatment while fungi and microorganisms can biologically degrade Geohumus.
