AbstractA single‐probe capacitance meter (Pasture Probe), the Hill Farm Research Organization (HFRO) sward stick, a rising‐plate meter, and cut quadrats were used to estimate herbage mass of swards that were rotationally grazed by cattle, cattle followed by topping, cattle followed by sheep, or sheep alone during 1989 and 1990 grazing seasons.

An automatic rising plate meter called the Ellinbank Pasture Meter (EPM) was constructed and evaluated at the Dairy Research Institute (Ellinbank) for measuring the dry matter present on a pasture dominated by green perennial rye grass. The meter readings of pasture height were found to correlate linearly with pasture yield, and the coefficient of ...

The ability of a rising plate meter and a direct plot-harvesting technique to detect differences in herbage mass was assessed on 3 occasions in an experiment comparing 2 different phosphorus fertilisers.Values of variance ratios (F-values) indicated that labour expended the techniques were similar in their ability to detect significant differences in ...

Pasture productivity is a key driver of profitability and sustainability in livestock systems. However, Ontario lacks standardized targets for pasture utilization, making it difficult for producers to benchmark performance. In contrast, countries like Ireland, the UK, and New Zealand have established national pasture utilization targets to guide sector

AbstractTo construct a new calibration method that combines usability and accuracy for estimating herbage mass from rising‐plate meter readings, we derived four models differing in the way their parameters are related to sampling date and compared their estimation accuracies using cross‐validation.

Non-destructive methods to derive spatial information on the development of forage mass are of key importance in managed grasslands. Established methods are rising plate meter (RPM) and rapid pasture meter, which both require in-field work, are rather time consuming, and do not provide spatially continuous data. Therefore, the overall objective of this

AbstractA rising plate meter (RPM) is an instrument used for the measurement of compressed sward height and estimation of yield on grasslands. The aim of this study was to investigate the use of an RPM to evaluate lucerne height as an agronomic trait enabling yield estimation.

A semi-automatic rising plate meter, the Ellinbank Pasture Meter (EPM) was used to estimate herbage yields of the three most common types of irrigated pasture intensively grazed by dairy cows in northern Victoria. While there were only small differences in precision between the pasture types, yields of pre-grazed pastures were measured more precisely ...
