Immediately start first cultivation after last pass with rotary hoe and cultivate two or more times depending on soil condition and degree-days. Propane burners may also be used for small weeds. Harvesting Organic Corn. To avoid excessive mechanical damage to kernels, make sure the combine is properly adjusted. If conventional crops are also harvested, the machine must be thoroughly cleaned between crops.
Corn can be machine dried using conventional methods.
Low-temperature drying is recommended for increased storability due to low breakage, less fines, improved aeration, and less opportunity for fungal growth. Grain kernel temperature should be kept below 140 F during the entire drying process to minimize undesirable quality losses. Field drying is often preferred for best kernel quality, if the weather permits. Corn Handling and Cleaning. Make sure that augers to and from the dryer are not causing damage.
