Farming irrigated corn on a thousand-acre farm in Nebraska is a big business with big bills that are getting bigger. Every year the University of Nebraska publishes detailed crop budgets that show typical costs. The numbers below come mainly from their 2025 and 2026 budgets for center-pivot irrigated corn. Yields in those budgets are usually about 250 bushels per acre, which is common for irrigated ground in the state. Your real costs will depend on your soil, the weather, the equipment you own and the prices you actually pay for seed and fertilizer.
Seed costs about $150 per acre. A bag of modern hybrid seed with insect and weed protection usually sells for about $350 and most farmers plant about 30,000 seeds per acre. On 1,000 acres, the total seed bill will be up to $150,000.
Fertilizer is one of the largest single expenses and costs about $150 per acre. Corn needs a lot of nitrogen — often up to 200 pounds per acre — plus some phosphorus and potassium. Farmers apply it as dry fertilizer, liquid or through the pivot (fertigation). Soil tests help determine the exact amount which saves money. For the whole farm, fertilizer costs can run up to $185,000.
Herbicide, which is the bulk of the cost, and insecticide together usually cost up to $125 per acre. Insect sprays are often a smaller part of the cost because many seed hybrids already protect against common pests. Custom applicators are commonly hired to do the spraying and for 1,000 acres, this can cost up to $125,000 for all pesticides combined.
Water and irrigation costs vary more than any other item. Pumping water through a center pivot costs up to $150 or more per acre, depending on whether you use electricity or diesel and how deep the water is. Most systems apply 9 to 18 inches of water over the season. While the water itself is relatively cheap, the energy to pump it and the cost of owning and repairing the pivot can add up. Electric pivots are usually cheaper to run than diesel ones. On 1,000 acres the total can easily reach $150,000.
Crop insurance averages about $16 per acre for revenue protection at about 70 percent coverage. The exact premium depends on your past yields and the county you farm in. For the full 1,000 acres, the insurance bill is usually about $16,000. Most lenders require it and it protects against big yield or price losses.
Labor costs run about $30 per acre and the budgets use a rate of about $27 per hour. This pays the people who plant, spray, check pivots and help at harvest, and larger farms often use a mix of family and outside hired help. Total labor for 1,000 acres is typically up to $30,000.
Machinery, tillage and field work cost $150 per acre in cash expenses for fuel, repairs and machine time. No-till systems cost less because they skip extra disking and cultivating. Conventional tillage needs more tractor hours. Harvest equipment like combines and grain carts are a major part of the bill and the cash total can reach $150,000. Owning the machines also brings depreciation and interest costs that can add another $100 per acre, but those are ownership costs rather than annual cash outlays.
Adding up the main operating costs — such as seed, fertilizer, chemicals, irrigation energy, insurance, labor and machinery cash costs — farm inputs usually reach $600,000 to $700,000 for the entire thousand-acre farm. If you include the full economic cost of owning land and machinery, the total can climb to $1.3 million.
Of course these costs change with fuel prices, fertilizer markets and rainfall amounts. A dry year means more pumping and a wet year means less. Good management, timely purchases and efficient equipment can help lower the totals.
The University of Nebraska offers a free online budget calculator where you can plug in your own numbers for seed rates, fertilizer, and equipment. Talking with a local Extension educator or crop consultant is also a smart step. Keeping careful records each year helps you see where the money is going and where you can improve.
