Use of Equipment

Poorly functioning equipment can jeopardize sample accuracy and sample precision. All measuring equipment, such as scales used to weigh samples for herbage biomass, should be regularly checked to confirm their accuracy. Other sources of measurement error include plastic tapes stretching with use and variations in pace-length among observers.
