You can turn that filthy waste to gas

Often, I get inquiries from farmers on issues such as ‘how can I increase the milk yield from my dairy cows? How can I control mastitis? How can I prevent my cattle from getting foot and mouth disease?’ etc. But the other day, I bumped into a unique query.

This reader complained of a farmer who had directed the discharge pipe from his zero grazing dairy unit onto a road and the water flows in to a stream. It was a nuisance and health hazard.
