Aluminosilicate lattices that hold up to 55% of their weight in water. Negatively charged, the lattices hold the cations of essential elements. Zeolites can be added to sandy soil to improve water and mineral retention. In gardens add 15–20#/100 sq ft to the top 6” before planting; 1–2-1/2 tons per acre. Added to compost, zeolites retain ammonium ions and prevent their transformation to ammonia gases, keeping the nitrogen from escaping. Helps reduce odors in animal litter.
