Yield prospects dip again for Wisconsin's corn, soybeans
A shortage of rainfall and several periods of hot weather have combined to put another dent on the yield outlook for Wisconsin's two major cash crops.
According to the update report for Sept. 1 issued by the Wisconsin field office of the National Agricultural Statistics Service (NASS), reductions were made in the projected per acre average yields for both corn and soybeans in the state.
Crop condition ratings of good to excellent dropped by 16 percentage points during August in the state - to 45 percent for corn and 46 percent for soybeans.
Wisconsin's grain corn crop is estimated to provide an average yield of 143 bushels per acre, down by one bushel from the Aug. 1 forecast.
This would put corn production at 465 million bushels - an increase of 16 percent from the more severely drought-affected 2012 crop.
As of Sept. 1, NASS was projecting a slight increase in the nation's corn crop compared to Aug. 1 and a 28-percent jump from the production in 2012. This would give the country a record production of 13.8 billion bushels of corn.
Those numbers are based on a harvest of 89.1 million acres of corn for grain with an average yield of 155.3 bushels per acre. This would be an increase of .9-bushel from the Aug. 1 forecast and 31.9 bushels above the 2012 average.
For soybeans, Wisconsin's average per acre yield was downsized by two bushels - to 40 bushels - compared to the Aug. 1 forecast. This would also be 1.5 bushels per acre less than the state's average soybean yield in 2012.
As a result, Wisconsin's soybean production is now forecast to be 66.8 million bushels from 1.67 million harvested acres. This would be a decrease of five percent from 2012.
Across the United States, the Sept. 1 outlook for soybeans indicated a total crop of 3.15 billion bushels - down by three percent from the Aug. 1 forecast but four percent more than in 2012.
The prediction for the nation's average yield is 41.4 bushels per acre from 76.4 million harvested acres compared to the 42.6 bushels expected a month earlier and the 39.6 bushel average in 2012.
NASS indicates that the crop yield predictions are based on field survey visits in the states that account for about 75 percent of the nation's production and on interviews with about 13,000 corn or soybean growers around the country.
