Nitrogen usage

Read a very good article by Steve Jones in The Daily Telegraph today ( p27) about our reliance on nitrogen in Agriculture and how this could give us all a bit of a hangover in the future which will be on the scale of carbon dioxide emissions. Nitrous oxide is one of the main breakdown products of excess fertilizer use and this is a greenhouse gas several times more potent than carbon dioxide.
Another very good reason to support growers like us who do not use manufactured fertilizers ! It is quite possible to achieve  the same results using green manure crops and a balanced rotation.
