Hydrogel
Hydrogel, also called solid water, is a potassium polyacrylate compound, which can absorb up to 268 times its weight in water through hydrogen bonding.
The hydrogel known as solid water is a potassium polyacrylate, which is in turn a potassium salt of polyacrylic acid, which has the property of absorbing aqueous solutions through hydrogen bonds with water molecules up to 268 times its weight. The hydrogel releases water along with nutrients in a sustained manner (keeping the soil moist), reduces nutrient loss and allows the development of microbial life in the rhizosphere and the absorption of nutrients in plants. In short, it is used to increase water and nutrient retention in soils.
