Despite the rain from November to January, the American cultures should still undergo a major water deficit in 2013. The drought of 2012, the worst in the last fifty years, has resulted in the soil drying out which is difficult for the farmers to manage.
According to the Palmer Drought Index, 56% of the U.S. are still in drought at the end of February, mainly in the High Plains region. Kansas, the largest producer of wheat in the United States, but also Nebraska, Oklahoma and South Dakota are in extreme drought according to the latest report from the U.S. Drought Monitor.
In the Midwest, where the bulk of U.S. corn is produced, rainfall can still balance a production that fell by 13% in 2012. The corn will be planted this spring on 24.1 million hectares according to the U.S. Department of Agriculture.
