A system of pasture yield measurement was developed for New Zealand’s pasture based, rotationally grazed farming systems. Pasture yield measurement is complex because the pasture biomass has to be measured in-situ,  pre and post grazing so that pasture consumption and utilisation can be calculated. The “Pasture Meter” was initially developed by Massey University and subsequently commercialised by C-Dax Ltd of New Zealand. The pasture management solution has solidified itself in the market-place and is considered a  valuable management tool for dairy farmers in New Zealand and Australia.   

The method of measurement is simple but highly effective  and provides reliable measurement of pasture cover in a range of pasture types regardless of weather and light conditions. The measurement unit is pulled behind an ATV and can be used at speeds of up to 20kmh^-1. Two technology levels are available, either as a basic system deriving average cover for individual paddocks, or with the incorporation of a  GPS to allow pasture production to be mapped. Recent independent calibration results from New Zealand based research organisations have shown the C-Dax Pasture Meter to have a higher level of accuracy than traditionally used methods as well as increased utility. The system has also proved to be reliable in measuring post grazing residual levels which are known as  Key Performance Indicators (KPI’s) to achieving good pasture management and maintaining pasture quality.

Measuring pasture covers allows farmers to make timely decisions regarding feed conservation, fertiliser use and stocking policies as well as giving farmers greater certainty in budgeting feed resources. The paper examines the KPI’s that farmers use to benchmark the success of their grazing management. A case study is  presented to illustrate how the C-Dax Pasture Meter is benefiting dairy farmers in New Zealand and Australia.
