Description
Paddock means of pasture yield and composition can be inadequate or even misleading due to the spatial variability within pastures. The use of visual estimation procedures, particularly the BOTANAL technique, provides data suitable for analysing variability as many quadrats are sampled within the one paddock. Examples show how data from routine BOTANAL samplings can reveal small and paddock scale spatial variation, and how BOTANAL data can be used to examine relationships between the yield of legume and grass in a mixed pasture grazed at different stocking rates.
