Pasture Biomass
Biomass monitoring was conducted on 12 June (day 32 of grazing trial) and 6 July (day 55, end of grazing trial). 6 sub samples were collected from barley and multispecies grazing trial and control (adjacent un-grazed paddocks sown at the same time) plots by randomly throwing out a 0.5 m² quadrat. Each sub sample was photographed prior to biomass removal. Biomass was removed at ground level and samples were dried at 85°C to constant weight (±1 g).
