    "problem_addressed": "Desertification, water scarcity, low-productivity sandy soils.",
    "concept_summary": "Liquid NanoClay is a patented mixture of water and finely disintegrated clay flakes. The mixture is sprayed onto dry sandy ground, where the nanoclay flakes coat individual sand particles via van der Waals forces, creating a sponge-like network that retains water and nutrients and acts as a catalyst for mycorrhizal fungi, dramatically increasing crop yields and cutting irrigation demand.",
