This month's heavy rains and flooding have reduced the value of Indiana's crops by nearly 300 million dollars and the damage could escalate with more wet weather. A Purdue ag economist says the projected corn and soybean harvest for the state dropped about 5 percent since the heavy rainfall began in early June. He says 15 percent or more of crops in some counties are in very poor condition. Some parts of northern Indiana have seen a foot or more of rain during this month.
