KBS020: Harvestable Biomass
In use from 1982-05-01
Abstract
Sampling Frequency: minimum of once per year
Harvestable biomass in each cropped plot is measured at the time of crop harvest . For grains, the agricultural grain harvester is fitted with a GPS-referenced yield monitoring system to provide yield maps for each 1 ha treatment plot . Additionally, grain is off-loaded into weigh wagons and weighed at the KBS dairy .
Alfalfa and wheat straw is measured on a gravimetric basis per plot after it has been cut and baled . Gravimetric moisture content is measured and subtracted from the biomass and the harvestable biomass estimate presented as dry weight alfalfa or straw per area .
