Margin Is Two Numbers, Not One
Most farm marketing focuses on the sale price. But your margin is price minus cost, and the cost side moves on its own schedule. Diesel, fertilizer, and seed can rise sharply in exactly the years crop prices disappoint — 2008 and 2022 both delivered that combination. Locking a good crop price while leaving input costs floating protects only half the equation.
The mindset that works: when you price a portion of the crop, consider pricing a portion of the inputs that produce it. You are not trying to win on either side. You are trying to capture a margin that covers your costs and pays you for the year.
Diesel: The One with a Real Market
Farm diesel tracks ultra-low sulfur diesel, and NYMEX heating oil futures are its direct hedgeable cousin. Commercial fuel users and larger operations routinely lock fuel costs two ways: forward contracts with fuel suppliers — fixed price, fixed gallons, no margin calls — or exchange hedges buying heating oil futures or call options against planned fuel needs. Even a rough hedge on your largest fuel months takes the worst-case scenario off the table. Futures trading involves substantial risk of loss and is not suitable for all investors, which is why many businesses prefer the forward route for cost hedging.
Fertilizer and Seed: Workarounds, Not Futures
There is no liquid futures market for urea, DAP, or potash that a farm can practically hedge with. What works instead:
- Forward pricing with your supplier. Many retailers will price fall or spring fertilizer in advance. That is a forward contract in everything but name — price certainty with a delivery obligation on their side.
- Watch natural gas. Natural gas is the primary feedstock for nitrogen fertilizer. Sustained gas rallies usually reach nitrogen prices with a lag — an early-warning signal you can actually act on.
- Time, then commit. Fertilizer has seasonal lows, often late summer. Buying a portion at seasonal weakness is a hedge executed with a checkbook instead of a brokerage account.
Seed is simpler: early-order discounts are the hedge, and trait decisions should be agronomic first. The common thread across all inputs is the same as across all marketing — decide in advance what a good outcome looks like, and take it when it is offered.
