Grey Dufferin Community Pasture Farm, Dundalk, Ontario is a 700 acre farm pasturing 600 head of cattle annually.
It operates rotational grazing with 4 watering stations, two of which are surrounded with 9' depth of shingle chips on a gravel base.

 

"It was a real wet year, but shingle chips stood up every bit as well as concrete and it cost less."
