Clover plants at the boundary with the barley were labelled with a foliar 15N application. Its distance from the clover boundary did not signifi-cantly affect nitrogen uptake by the barley. However measurements of the isotopic label showed a transfer of 2.5% of the N from the red clover and 1% of the N from the white clover to the barley over short dis-tances. The study has indicated that transfer of N between clover and cereals is spatially limited and at least within the first year, it is unlikely to provide agronomically significant supplies of N 2006 published public 5614 1 7368 1 source en public
