An Iowa official says crops planted too close to county roads pose safety and other hazards.
The Mason City Globe Gazette reports that some farmers have pulled up their fences so they can plant more ground closer to county roadways.
County engineer Mary Kelly she understands the farmers' desire to "get the biggest bang for their buck."
But Kelly says planting in the county easements on ditch sides and bottoms can create drainage and erosion problems. Also, as crops grow they can obscure a driver's vision.
Kelly says a tall crop of corn near a road might prevent a driver from stopping in time for a deer coming out of the field.
