How does corn dry in the field? - Farm Progress
2020年9月30日 · How does corn dry down to harvestable moisture levels after it reaches black layer? In a typical season, grain drying in the field ranges from 0.5% to 0.8% moisture loss per day, which occurs mostly by evaporation. Even if hybrids have similar relative maturity ratings, some dry down faster than others.
Field Drydown of Mature Corn Grain - Purdue University
Field drying of mature corn grain is influenced primarily by weather factors, especially temperature, humidity, and rainfall. Simply put, warmer temperatures and lower humidity encourage rapid field drying of corn grain.
Varying in-field moisture makes corn harvest, drying, storage a ...
2024年10月11日 · The two preferred options for large corn moisture content variations in a field are to wait for the high-moisture corn to dry before harvesting the field, or to harvest the dry portion now and wait for the rest to dry. Drying and storage concerns will arise if the corn is dried with large moisture content variations, warns Hellevang.
Field drying of mature corn grain is influenced primarily by weather factors (especially temperature and humidity) and, to a somewhat lesser degree, by ear and husk characteristics of hybrids.

2018年9月17日 · Field drying of mature corn grain is influenced primarily by weather factors, especially temperature, humidity, and rainfall. Simply put, warmer temperatures and lower humidity encourage rapid field drying of corn grain.
Corn Grain Dry Down in Field From Maturity to Harvest
2017年9月20日 · Corn grain dry down in the field is expected to be at a rate of 0.69% per day in the first 20 days following maturity. This can be used to help schedule harvest of fields based on when fields and hybrids reach maturity.
Harvest Loss, Drying Costs, and Discounts | Crop Science US - Bayer
2022年9月21日 · Allowing corn to dry in the field could lead to harvest losses of 2 to 8% above the normal levels of a timely and efficient harvest. 2 Table 1 estimates the energy cost to dry corn and the value of excess harvest losses based on a yield …
Field Drydown of Mature Corn Grain: Key Insights for Farmers
2024年9月16日 · Field drydown refers to the natural reduction in moisture content of mature corn grain while still in the field. Corn typically reaches physiological maturity when the kernels have formed a black layer, indicating that they have stopped accumulating moisture.
Realistic Expectations for Field Dry Down in Corn
2020年8月22日 · Delaying harvest until corn dries down to 16% to 18% moisture content can save on artificial drying costs. However, as corn dries down in the field there is greater potential for excess harvest losses from stalk lodging and ear-drop. Most harvest losses are mechanical, caused by kernel shattering or corn never getting into the combine.
Several factors influence field drydown after maturity. Kernel moisture content decreases faster with warm, dry weather and may decrease slowly in a wet and cool environment. Fuller season corn products, that require more growing degree units (GDUs) to mature, will likely be slower drying as the fall progresses within an area.
