Ammonium Sulfate Storage — Agricultural Fertilizer Tank Selection
Storing Ammonium Sulfate? Start Here
Ammonium sulfate (AMS, "sulfur-21") is a high-volume nitrogen fertilizer and a mild, easy chemical to store. A standard poly tank handles it without fuss.
Can you store it in a poly tank? Yes.
Ammonium sulfate solution is compatible with HDPE/XLPE — a 1.5 SG tank covers it (1.9 SG for extra margin), with PVC fittings, EPDM gaskets, and 316SS bolts. No carbon-steel wetted parts. Tanks run 500–30,000 gallons from farm to dealer scale.
The safety that actually matters
Low-hazard (mild dust irritant). Standard PPE, a simple vent, and 110% containment. The main note is just keeping bare steel off the wetted side.
Common questions
- Poly OK for ammonium sulfate?
- Yes — HDPE/XLPE, 1.5–1.9 SG, EPDM gaskets, no carbon steel. It's an easy fertilizer to store.
- What size tank?
- Anywhere from 500 gallons (farm) to 30,000 (dealer). Size for your turnover.
