Horse pasture help.
HI we're fencing in a new pasture for my horse. It's on the edge of our property and our yard is next to a field/farming land. The farmer plants crops there every year and he uses/sprays herbicides/pesticides(not sure) on the crops several times a (growing)year. The pasture is going to be next to the farmer's land and I was wondering if I should be concerned about the stuff he sprays and would it be safe for my horse to graze there after the farmer sprayed the field? The pasture wouldnt be sprayed, though.
