TerraCottem soil conditioning uses the power of disposable diapers to increase crop yields in Willem van Cotthem’s gardening invention. Disposable diapers use powerful absorbent polymers that suck up hundreds of times their weight in water. The absorbent polymers are called hydrogels.
Hydrogels have only recently become non-toxic and suitable for use in growing food for human consumption. They are the basis of van Cotthem’s ‘Terracottem’ soil conditioning, in which hydrogels and organic agents nourish the natural bacteria in the soil.
