DES MOINES, Iowa (AP) – The condition of the state’s corn and soybeans crops have improved and dry weather has allowed the fall harvest to begin in Iowa. Iowa Secretary of Agriculture Bill Northey released his weekly update on the condition of the state’s crops Monday, saying one-third of the corn crop is mature. That’s behind 56 percent at this time last year but ahead of normal, which is 30 percent. Fifty-seven percent of the corn crop is in good or excellent shape; 28 percent fair and 15 percent poor or very poor. About half of the state’s soybeans are turning color, behind 70 percent last year and behind the five-year average of 63 percent. Sixty-four percent of the soybeans are in good or excellent condition with 12 percent being poor or very poor.
