Abstract
Methods of measuring grassland and forage grass and legume dry matter and organic matter yields are described with reference to sampling procedures, destructive techniques, non-destructive techniques (direct visual estimation, height + density, capacitance, spectral analysis/remote sensing, and modelling). Methods suitable for shrubs and trees, for determining the composition of the yield, for estimation of growth and utilization, and the use of exclosures are included. It is concluded that the selection of a suitable method for determining biomass depends on the scale of the experiment, the purpose for which the data are required, the accuracy required and the resources available.
