Rock County held steady in 2017 as one of Wisconsin’s most productive agriculture counties.

The U.S. Department of Agriculture released its 2017 county harvest estimates for corn and soybeans. The data include information on crop yields and acres harvested.

Rock County was one of six counties in the state to surpass both 180 bushels of corn per acre and 50 bushels of soybeans per acre, along with Columbia, Dane, Dodge, Grant and Lafayette.

Walworth County’s numbers don’t quite stack up to the more productive southwestern and south central regions of the state. But it remains a solidly second-tier county for field crop production.

Here’s a by-the-numbers look at some of the county-level data, according to the U.S. Department of Agriculture:


Rock County rank in corn and soybean production in Wisconsin as measured by bushels harvested per acre.

Adding its average corn and soybean yields, Rock has a net field crop harvest of 244.9 bushels per acre. That ranks fourth behind Lafayette (262.4), Grant (246.9) and Columbia (245.3).

Rock County’s corn production decrease in 2017, following its record-setting harvest the previous year.

Most of the state’s major agriculture counties had small decreases from 2016. Here, a rainy spring delayed the planting season, and flooded fields ruined production in some low spots. Rock County had a smaller decline than statewide corn production, which dipped by 11 percent.

The combined increase in soybean acreage in Rock and Walworth counties.

The two counties planted a cumulative 17,000 more acres of soybeans in 2017 than in 2016. Wisconsin corn prices have not been above $4 per bushel since July 2014. Even that was a steep fall from spring 2013, when corn prices hovered at a lucrative $7 per bushel. Soybeans have mostly earned more than $9 per bushel as corn slumps. Increased soybean acreage indicates farmers tried to take advantage of better prices.


Bushels of corn per acre in Lafayette County, the highest tally in Wisconsin.

Lafayette also had the highest soybean total at 56.4 bushels per acre. That made it the most efficient field crop producer in the state by a considerable margin.
