The Minnesota House has “dug” through the options and voted to name Lester the official state soil. The House approved the choice as part of an agriculture policy bill on a vote of 111-20 Tuesday. It passed in the Senate later in the day, and now goes to Governor Dayton for approval. Soil experts say Lester was formed 10,000 years ago and is effective for growing plants. The loamy soil is named for the McLeod County community of Lester Prairie, and covers more than 600,000 acres in 17 Minnesota counties. Lester would join 16 other state symbols, including the state flower, the pink and white lady slipper; the state tree, the Norway pine; the state drink, milk; and the state muffin, blueberry.
