Forty-five farmers from Calvert County visited the Zimmerman farm in southern Carroll County on Nov. 12 to view the family's conservation and crop-management practices.
"This is a model of what a modern farm should be," said Ed Knoll of the Carroll Soil Conservation District.
The farm is part of the Monocacy demonstration project, which is trying to protect the water quality around the Piney Run reservoir area, he said.
