Corn, soybeans and wheat reported marketing year lows:

It's been a weather market this week, with dry Argentine forecasts helping soybean prices, although they’re still more than 30 cents lower than they were, also due to South American weather factors (timely Brazil rains in December).  Wheat had been doing somewhat better over winterkill concerns in the Plains, but bad export data sunk some of those gains today.

Next week there are some updates to U.S. agricultural trade data on Monday and then on Friday, winter wheat seedings and season-average price data updates from USDA and WASDE is released.
