- Compare quotes to USDA AMS benchmark — USDA publishes weekly retail fertilizer prices by region. If your quote is more than 8% above benchmark, push back.
- Watch NOLA barge prices — terminal prices follow NOLA barge within 2–3 weeks. A barge price drop signals incoming retail relief.
- Pre-buy fall applications before August — China export restriction decisions in August will move the market; pre-buying locks in current prices.
