Zeolites can improve the productivity of any texture of soil, improving water and mineral retention in sandy soils and improving aeration and minimizing compaction in heavier soils. Added to compost, zeolites retain ammonium ions and prevent their transformation to ammonia gases, keeping the nitrogen from escaping into the air.
Add 2–3# for each 10# of potting soil. In gardens add 150–200#/1000 sq ft to the top 6" before planting. Spread 2,000–5,000#/acre. Water thoroughly after application so the zeolites will absorb the moisture, holding it in a thin film on their surfaces until needed. MOFGA
