The 2020 derecho left large amounts of downed corn as it swept across Iowa. Farmers faced the challenge of determining the best way to deal with this corn, which in some cases is being left in the field. Most of these fields will be planted to soybean in 2021, which brings up an interesting...

2020 corn harvest in Iowa is likely to include increased amounts of damaged grain from the drought, derecho, or excessively dry corn at harvest. As grain bins are filled, fines and broken or damaged kernels tend to accumulate near the center of the grain pile, while whole and higher quality...

Unusually warm weather in Iowa the second week of October led to rapid in-field drying of crops. Many farmers now find corn at 11 to 14 percent moisture content in the field. Excessively dry corn is more brittle and susceptible to mechanical damage during harvest. Dr. Charles Hurburgh notes that...

Recent warm weather was great for drying crops in the field, but resulted in warm grain going into farm storage. Cool that stored grain as soon as possible to extend storage life. Forecast temperatures for the next several days are favorable for cooling stored grain to around 45 degrees.
