Work out biomass estimation instantly with clear inputs, formula shown and shareable results.
Converts harvested wet mass to dry biomass and scales it per unit area, with carbon at the conventional half of dry mass.
Biomass
Dry mass = wet mass x dry matter fraction; per hectare = dry mass / plot area x 10,000; carbon is about 50% of dry mass
Water content varies with weather and time of day, so wet mass is not comparable between samples.
It is the standard default for woody biomass; herbaceous tissue is often nearer 45%.
