Crop Summary
Timely planting, good soil moisture and temperature resulted in good seedling emergence. Above-average rainfall during April and May resulted in slow growth, but the corn recovered quickly during a dry period in July. Normal temperatures during July and August resulted in good grain production by harvest time in early September. The previous crop was wheat. The land was prepared by disc and do-all flat before planting.
