An apparatus for measuring pasture forage mass

摘要：

Measurement of forage mass (FM) is crucial in evaluating grazing strategies and setting appropriate stocking rates.Pasture variability usually requires multiple samples for accurate FM evaluation, a labor‐intensive process.Rapid, nondestructive techniques can provide reliable FM estimates, but accuracy depends on multiple point readings from an unbiased operator.Continuous measurement of compressed forage height may be more representative.A forage estimator was designed to measure and digitally record georeferenced data.This study evaluates estimator data from two dissimilar grasses.
