http://orgprints.org/7368/ Nitrogen uptake by spring barley grown with red and white clover Rees, Dr Robert Baddeley, Dr John Bingham, Dr Ian Watson, Dr Christine Nutrient turnover A field experiment was undertaken to measure the uptake by spring barley of nitrogen at different distances from a boundary with either red or white clover. 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 Conference paper, poster, etc. NonPeerReviewed source http://orgprints.org/7368/1/Nitrogen_transfer_between_clover_and_barleyFinal.doc Rees, Dr Robert; Baddeley, Dr John; Bingham, Dr Ian and Watson, Dr Christine (2006) Nitrogen uptake by spring barley grown with red and white clover.
