STOCKOSORB is a superabsorbent soil amendment specially designed to retain water and plant nutrients, and on demand, release both water and nutrients to plants and the surrounding soil. STOCKOSORB increases the usable water-holding capacity of soils and potting mixes on a long-term basis while providing a continuously available water reservoir where the plants need it – in the root zone.
