Field Evaluation of a Rising Plate Meter to Estimate Herbage Mass in Austrian Pastures [PDF]
Sensors, 2023 Pasture management is an important topic for dairy farms with grazing systems. Herbage mass (HM) is a key measure, and estimations of HM content in pastures allow for informed decisions in pasture management.

Accounting for minimum data required to train a machine learning model to accurately monitor Australian dairy pastures using remote sensing [PDF]
Scientific ReportsPrecision in grazing management is highly dependent on accurate pasture monitoring. Typically, this is often overlooked because existing approaches are labour-intensive, need calibration, and are commonly perceived as inaccurate.

Estimation of grass biomass consumed by rabbits housed in movable paddocks
World Rabbit Science, 2023 Biomass allowance is a key feature in pasture-based rabbit production systems. It conditions not only the stock density (rabbits/m²) and/or the number of grazing days, it also influences the grazing behaviour of animals.

Evaluation of a Rising Plate Meter for Use in Multispecies Swards
Agricultural & Environmental Letters, 2016 The rising plate meter (RPM) provides rapid estimates of herbage mass (HM). Accurate calibration of the RPM is difficult due to variability in forage management, growth, and species composition.

Micro-sonic sensor technology enables enhanced grass height measurement by a Rising Plate Meter
Information Processing in Agriculture, 2019 Globally, the Rising Plate Meter (RPM) is a device used to measure compressed sward height, to enable estimation of herbage mass. Despite improved farm management practices aided by a variety of technological advances, the standard design of a RPM has ...

A Technique of Direct Tension Measurement of a Strung Fine Wire [PDF]
, 1998 We present a new technique of direct measurement of wire tensions in wire chambers. A specially designed circuit plucks the wire using the Lorentz force and measures the frequency of damped transverse oscillations of the wire.
