Dinitrogen Fixation by Hairy Vetch (Vicia villosaL.) in a Low-Chemical Input Cropping System
Measurements of dinitrogen fixation potential (acetylene reduction assay) and biomass and N accretion in hairy vetch used as a winter cover in low-chemical input cropping systems. Aboveground biomass accumulation is measured in the low-chemical input cropping system described in KBS004, and aboveground and belowground biomass (roots, nodules) and N2 fixation by intact nodules is measured in a subset of ancillary plots with different levels of available soil nitrogen.
