News From The Coffee Shop asked several Crop Professionals across Northeast Iowa to shed some light on the unusually early Spring weather and discuss the risks and rewards associated with getting seed in the ground early.
Thanks for tuning in over the past week to read what the local pros are saying about early planting!

Frost Damage risk
Although the growing point on corn is below the soil surface until the five leaf collar stage (V5), new growth often has trouble emerging through frost-damaged tissue, resulting in buggy-whipped plants. Frost damage to plants that are 6 in. or shorter can reduce yield by 9-15%, and is likely related to the subsequent unevenness in the stand and completion among plants.
When a corn plant was one leaf stage behind neighboring plants early in the season, its yield was reduced by 20%. In comparison, when a corn plant was two leaf stages behind neighboring plants early in the season, its yield was reduced by 51%.
Crop Insurance Dates
Early planting before April 11 for corn and April 21 for soybeans will cost you prevented planting dollars.
Early April planting has been a topic of discussion. Is it a good or bad idea? The past few years early planting has been very popular due to warm soil conditions. According to University of Illinois agronomist Emerson Nafziger. "Once soil conditions are good for planting in April, there probably should be little hesitation in getting started." Soil temperature is not a consideration.
If conditions are favorable and the 7 – 10 day forecast is good there is no reason not to get started on planting. Your biggest factors are a May frost (latest frost date for Waterloo IA is May 1 50% and May 12 10% chance according to ISU Extentions Office) and pest control. Consider all factors and do what fits your operation. Be aware as the temperatures increase and we gain GDU’s corn growth becomes rapid. My biggest concern with the warm weather is growing to fast and catching that late May early June wind storm and getting green snap.
