There's still time for area farmers to plant soybeans.
ISU Extension Office Crop Specialist Brian Lang in Decorah says farmers can switch to an earlier season variety. If a late planting is feasible, Lang recommends using narrower rows (i.e. 15 or 20-inch vs. 30-inch) and increasing the seed population a bit, since late-planted soybeans don't cover the rows as well as the earlier planted soybeans do.
Lang also says for corn fields, the long-term average GDD (growing degree days) for late June is about 20 per day.
