In which city is the Department of Agriculture and Land Stewardship located?

The Department of Agriculture and Land Stewardship for the state of Iowa is located in Des Moines. This is significant because Des Moines is not only the capital but also the administrative center of Iowa, hosting many key state agencies and departments. The department's focus includes promoting and regulating the agriculture industry in Iowa, which plays a critical role in the state's economy. The other cities mentioned, such as Sioux City, Cedar Rapids, and Iowa City, while important, do not serve as the administrative headquarters for this particular department, making Des Moines the correct answer.
