NORTHFIELD, Minnesota — The tomatillos hang in small-green balls from the vine, water-logged. The chilis sprouting up in a mucky row are puny. The garbanzo: Finished. Floods killed these crops. But unlike the large corn and soybean spreads in south central Minnesota — dotted with ponds after historic June flooding — federal crop insurance covers none of these crops. “Last year’s harvest would fill baskets,” said Erika Gomez of Tierra de Esperanza Farm, a quarter-acre operation on the grounds of Sharing Our Roots farm in rural Dakota County. Gomez said in Spanish through a translator that one day last year, she and her partner picked 600 pounds of produce to sell at local markets.
