Corn Storage - Wisconsin Corn AgronomyIf drying is unavoidable, consider allowing crops to dry in the field as much as possible to reduce energy costs. Keep in mind, however, that there is a point where field losses will increase. One also has to account for the time needed to harvest grain based on the capacity of your equipment and the risk of weather damage or weather impeding harvest. Chapter 8 in the Corn Handbook on Corn Harvesting by Huitink discusses how to estimating field losses . The moisture content of the standing grain at harvest initiation will depend on weather conditions, the amount of grain to harvest and harvest and drying capacity. Corn kernel mechanical damage during harvest is usually lowest between 19 percent to 24 percent moisture [3,4].

EAR CORN STORAGE - CORN CRIBS
The equilibrium moisture content EMC of a hygroscopic material surrounded at least partially by air is the moisture content at which the material is neither gaining nor losing moisture. The value of the EMC depends on the material and the relative humidity and temperature of the air with which it is in contact. The speed with which it is approached depends on the properties of the material, the surface-area-to-volume ratio of its shape, and the speed with which humidity is carried away or towards the material e. The moisture content of grains is an essential property in food storage. At a constant relative humidity of air, the EMC will drop by about 0. The following table shows the equilibriums for a number of grains data from . These values are only approximations since the exact values depend on the specific variety of a grain.
If late fall and winter are so damp that grain does not dry, spoilage will begin with the onset of warm weather in the spring. Corn should be down to A bushel of corn at Thus, the farmer would have delivered bushels x 0. Usually a 0.
