When to Buy Fertilizer — 2026 Timing Guide

The best time to buy fertilizer in 2026 depends on the product. Potash: buy now — it is the most attractively priced major input. Phosphate (DAP/MAP): hold on large pre-buys until the August China restriction decision, but buy immediate needs. Nitrogen: pre-book fall anhydrous before August; China export restriction news will move the market. Herbicides: buy glyphosate and atrazine now before tariff changes.

Why Fertilizer Buying Timing Matters

USDA AMS data consistently shows 10–20% price variation for the same fertilizer between pre-season and peak-demand pricing. On a 500-acre corn operation spending $250,000 on fertilizer, a 15% improvement in buying timing saves $37,500 per year.
