STOCKOSORB® 660 is based on a hydrogel technology designed for the agricultural and horticultural sectors for water and soil management. STOCKOSORB® 660 stores hundreds of times its weight in water. On demand, as soil conditions turn dry, nutrient-rich water is released to the plant root zone where it is most needed. STOCKOSORB® 660 helps create constant moisture conditions in the root zone of the plant. It provides a moisture buffer against insufficient rainfall and watering, heat and drought.
