SYNOPSIS

A widespread rainfall event passed through northeast Illinois putting a temporary hold on harvest activities. This pause gives growers the opportunity to visit fields and evaluate combine performance in harvested areas. This is also one of the easiest times to measure harvest populations in corn fields. For 30-inch rows, count the number of plants in 17 feet 5 inches and multiply by 1000 to determine population per acre. Winter annuals have started to grow, including common chickweed and henbit in northeast fields. Several reports of soy as dry as 9 percent moisture have been shared. The following recommendations originated from the University of Nebraska in reference to soybean harvest, “moisture content can increase by several points with an overnight dew or it can decrease by several points during a day with low humidity and windy conditions. Avoid harvesting when beans are driest, such as on hot afternoons, to maintain moisture and reduce shattering losses. Harvesting immediately after a rain, if field conditions allow, will result in higher moisture contents. However, several wetting and drying cycles from rain events will make the soybeans more susceptible to shatter losses from pods splitting open.” The full UNL article for equipment adjustment for harvesting soybean can be accessed at https://cropwatch.unl.edu/2017/tips-harvesting-soybeans-13-15-moisture
