Abstract
Barley receiving unlabelled nitrogen fertilizer was grown among treatm ents receiving (Ca(NO3)2)-N-15 fertilizer (5 atom %) in a growth cabin et with high air exchange and in a greenhouse. In both environments, t he unlabelled plants and soil were significantly enriched with 15N, ap parently, in part, by foliar exchange of atmospheric ammonia. This exc hange may warrant consideration in the selection of appropriate contro ls for N-15 calculations.
