Abstract

Purification role of hedgerows was assessed in nitrogen-polluted agricultural landscape of Wensleydale (North Yorkshire, United Kingdom). Air chemistry was greatly influenced here by a pig farm producing ammonia. It was found that hedges change the rainfall chemism and act as biofilters at landscape level. Their efficiency depends on their pattern within the territory and their structural parameters.
