USDA’s National Agricultural Statistics Service (NASS) will review all available data, including survey data, satellite-based data, and the latest information from USDA’s Farm Service Agency and Risk Management Agency, for planted and harvested acreage for corn, cotton, peanuts, rice, sorghum, soybeans, and sugarbeets in preparation for the September Crop Production report. If the data review justifies any changes, NASS will publish updated planted and harvested acreage estimates in the Sept. 10 report.
It is normal practice for NASS to review these data in September for cotton, peanuts, and rice. The review typically takes place in October for corn, sorghum, soybeans, and sugarbeets, however the data are sufficiently complete this year to consider adjustments in September. In October, NASS will again review acreage for corn, sorghum, soybeans, and sugarbeets as well as for canola, dry edible beans, and sunflowers.
