  • Soil-activating agent and its application
    Patent number: 4755205
    Abstract: A soil-activating agent for extreme soils, for instance soils with very little organic substances or none at all and/or high contents of salts and/or heavy metals, is characterized by the combination of a fungal mycelium biomass and the tertiary system nitrogen-base/sugar-type/phosphoric-acid. This agent is characterized by an especially rapid and dense greening of extreme soils, in particular those with very little or no organic substances, and in that additional content of deleterious materials can be tolerated.
