This Week's Weather & Pests

The growing season of 2013 was characterized by two distinct weather patterns. The months of April, May and June were unusually cold and wet, while July, August and September were abnormally dry. Cool soils, combined with substantial April precipitation, resulted in the slowest corn planting pace since 1984, with just 4% of the crop in the ground by May 5. Significant planting delays continued through-
out May, allowing for only narrow windows of favorable conditions to plant this year's crops. By June 1, more than of intended corn acres and of intended soybean acres were still unplanted.

In stark contrast, a drying trend began in July and intensified during August. At the start of September, topsoil moisture was very short or short for 72% of the state and crop conditions were rapidly deteriorating. Much-needed rain in October and November improved soil moisture deficits and a later-than-average mid-October killing frost afforded late-planted crops additional time to mature, contributing to better than expected corn and soybean yields this year.
