Nitrogen cycling in an alfalfa-bromegrass sward
Contribution of hay harvest losses and "leaf fall" to N cycling and the N nutrition of intercropped alfalfa and bromegrass
A significant amount of forage plant biomass is deposited on the ground as senescent leaves, petioles and flowers (leaf fall). In addition, a varying amount of plant biomass is lost during harvest of hay crops (hay loss). ...
Herbage and protein productivity of single or inter-cropped alfalfa and bromegrass under zero nitrogen fertilization
Nitrogen (N) fertilizer enhances the growth of grass in grass-legume associations and frequently inhibits N2 fixation by the legume-Rhizobium symbiosis. The cost of N fertilizer and environmental concerns related to ...
