Drying costs will be higher this fall because LPGas prices have and are rising quickly during the past few weeks. Corn growers may want to delay harvest to allow for more field drying which could reduce drying costs. How much field drying can be expected?
Field drying is an evaporative process of moisture moving out of kernels through the husks. High temperature and low humidity are the primary factors, which drive the rate of field drying. Husk looseness is an important plant characteristic that helps to speed kernel moisture loss. Other factors are wind speed and sunshine hours that contribute to field drying.
