Post-Harvest Management Keys for Missouri Farmers
The Hidden Half of the Harvest
Harvest marks the end of a long season, but for Missouri farmers, it’s not the finish line; it’s the starting point for maximizing revenue. Post-harvest decisions around drying, storing, handling and marketing grain can make or break a farm’s bottom line.
“Farmers spend a lot of time and energy focused on production, but what happens after the combine leaves the field is just as important,” University of Missouri agronomy professor Kelly Nelson says. “Storage and marketing are important components of production to avoid leaving money on the table.”
Preserving Quality in Drying and Storage
Missouri’s humid fall conditions make grain drying a critical first step. Corn and soybeans harvested above safe moisture levels (15% for corn, 13% for soybeans) risk spoilage. Farmers can use on-farm dryers or contract with local elevators, but each option comes with costs and benefits.
On-farm systems give farmers more flexibility to wait for better market prices, while commercial dryers reduce labor and capital requirements.
University of Missouri specialists say the key is knowing your break-even and how a few cents saved on drying costs can add up over thousands of bushels.
Once grain is dry, storage management becomes vital. Regular monitoring for temperature, moisture migration, and pests prevents shrink and quality loss. Aeration fans should run during cool, dry nights to maintain uniform conditions inside bins.
Marketing: Timing Matters
Grain prices often rebound after harvest as supply tightens. Farmers who can store grain have more flexibility to wait for seasonal rallies or contract forward sales.
“Storage gives producers more options. Prices tend to be lowest at harvest time, so it can be valuable to have the flexibility that storage provides,” says Pat Westhoff, Mizzou agricultural economics professor and director of the Food and Agricultural Policy Research Institute
Farmers can also explore basis contracts, hedge-to-arrive contracts, or options through their local elevator or grain merchandiser. Working with a trusted grain marketing advisor helps navigate price risk while capturing opportunities.
Managing Residue and Field Prep
While grain is moving off the farm, the fields themselves may need attention. Residue management, especially after corn, affects next season’s emergence and disease pressure. Chopping stalks, light tillage or cover crops can help accelerate residue breakdown and protect soil structure over the winter.
“A focus on conservation residue management is important to protect the soil during the winter months when fields are fallow” Nelson says. “Thinking ahead for next year’s soybean crop is an important consideration.”
Financial Payoff
In the end, post-harvest management is about capturing the full value of what’s already been grown. When done right, it can add 10 to 20 cents per bushel, or more, through higher quality, reduced shrink and better timing.
“Small decisions after harvest are important, especially when profit margins are tight,” Nelson adds. “You have taken all of the critical production risks. Now is the time to get paid for them.”
5 Tips to Cut Storage Loss
- Harvest at the Right Moisture
Harvest corn at 20–25% and soybeans at 13–15% moisture, then dry to safe storage levels (15% for corn, 13% for soybeans) to avoid spoilage. - Cool Grain Quickly
Run aeration fans during cool, dry nights right after binning to bring grain temperatures down below 50°F, which slows insect and mold activity. - Monitor Bins Weekly
Check temperature cables, moisture levels, and grain condition regularly. Early detection of hot spots can prevent major losses. - Keep Grain Level and Cored
After filling, pull grain out of the center of the bin to remove fines and level the surface for better airflow and uniform drying. - Seal Out Pests and Moisture
Inspect bins for leaks, clean up spilled grain around the site and maintain good sanitation to keep rodents, birds, and insects from moving in.
