Corn stocks in all positions totaled 9.02 billion bushels on March 1, 2026, up 11% from the same date last year, according to the USDA’s National Agricultural Statistics Service (NASS) Grain Stocks report. On-farm corn stocks rose 21% to 5.43 billion bushels, while off-farm stocks decreased 2% to 3.59 billion bushels.
Soybean stocks also increased, totaling 2.10 billion bushels, a 10% rise from March 2025. On-farm soybean stocks were up 3% at 900 million bushels, and off-farm stocks climbed 16% to 1.20 billion bushels.
All wheat stocks reached 1.30 billion bushels, a 5% increase from last year. On-farm wheat stocks declined 3% to 298 million bushels, but off-farm stocks rose 8% to 1 billion bushels. Durum wheat stocks grew 21% to 46.5 million bushels, with on-farm stocks up 40% and off-farm stocks down 4%.
Other grains showed mixed trends. Barley stocks fell 10% to 92.9 million bushels, with both on-farm and off-farm stocks declining. Oat stocks decreased 3% to 41 million bushels, despite a 14% increase in on-farm stocks. Sorghum stocks rose 15% to 172 million bushels, driven by a 58% increase in on-farm storage.
Sunflower stocks surged 41% to 899 million pounds, with oil-type sunflower seed accounting for the majority of the increase.
The report also highlighted indicated disappearance—grain usage during December 2025 through February 2026. Corn disappearance rose to 4.28 billion bushels, up from 3.93 billion last year. Soybean disappearance slightly declined by 1%, while wheat disappearance increased 12%.
NASS based these estimates on surveys of nearly 74,000 farm operators and approximately 7,800 commercial storage facilities conducted in early March. The data provide critical insight into grain supply and storage trends as the 2026 planting season approaches.
