Friday mornings from Jan. 4 to Feb. 8 Nebraska Extension in Lancaster County will host a meeting series on timely topics for eastern Nebraska farmers. Can't get into town that day? The sessions will also be live streamed.
Statistics indicate that first freeze (28°F) trends for southeast Nebraska are changing, moving slightly later into the fall while those for northwest Nebraska, at the other end of the scale, are not changing. See average first freeze date ranges here.
Ponding or flooding of fields affects corn differently at different stages, depending on duration of flooding and other factors. Growers should assess the potential for nitrogen loss and increase scouting for corn disease in these fields.
Soybean plants are generally able to withstand a fair amount of flooding in the short term; however, diseases favored by wet conditions may become a problem for the rest of the season. Research shows the length of time the soil is wet and the type of soil will affect plant injury and survival.
Do cover crops affect CO2 emissions from the soil and if so, under what conditions? These were among the questions addressed by university researchers monitoring CO2 emissions from cereal rye cover crops in irrigated and dryland no-till continuous corn treatments.
