Field and laboratory methods for grassland and animal production research.

Book cover for Field and laboratory methods for grassland and animal production research.

Description

This book brings together a range of methods used to study grasslands (both temperate and tropical) and ruminant performance, including: grassland vegetation and its measurement; pattern analysis in grassland and animal production systems; modelling pasture and animal production; measuring botanical composition of grasslands; measuring sward structure; plant population dynamics in grasslands; meas...

Measuring biomass of grassland vegetation.

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.
