Wisconsin farmers are starting to get behind on their spring field work, as many wait for muddy conditions to dry up. The Wisconsin Ag Statistics Service says spring tillage is two-percent finished, same as last year but three points behind the average for the past five years. Thirty-percent of Wisconsin farm fields have surplus moisture, with only one-percent reporting a shortage. Forty-five percent of pastures are rated good to excellent, three-percent fewer than last year at this time. Four percent of the state’s oats have been planted, three-percent behind the norm.
