Historical State Corn Production
CropProphet is a crop yield and forecasting system. We independently model the impact of weather on both yield and production on corn crops for the United States. For example, our corn yield forecast is based on a model of bushels of corn yield per harvested acre. USDA NASS estimates of corn yield are reported as corn yield harvested acre.
Our corn production by state forecast, however, is based on a statistical model of corn yield per planted acre. This is not the same as corn yield per harvested acre. Reviewing the history of corn production, usually reported in units of billions of bushels, in key states helps provide context to the CropProphet corn production forecast.
The information below is provided by the USDA NASS and documents the corn production history of the major corn-producing states in the United States. CropProphet, a corn production forecasting product, is designed to forecast the year to year variations of corn production.
An analysis of state corn production history data indicates there are three causes of corn production variations at the regional level in the United States. Each is important to creating an accurate corn production forecast. The causes of year-to-year corn production variation at the state and national level are:
- The number of acres of corn planted in any year. Production is the number of acres harvested multiplied by the yield of those acres.
- The corn yield technology trend – many types of technology are improving yields corn. The result is an increase in how much crop can be produced on a given acre of farm-land. The charts below show corn yields from 1986 to 2017 as reported by the USDA. The general upward slope of the line is the technology trend.
- Weather conditions during the corn growing season – after removing the effect of the technology trend, the impact of weather on corn can be estimated. The variations around the upward trend in the data on these charts are caused by weather conditions during the US growing season. CropProphet uses the evolving weather conditions during each crop season to forecast end-of-season corn production.
