Comparison of Ground-Based, Unmanned Aerial Vehicles and Satellite Remote Sensing Technologies for Monitoring Pasture Biomass on Dairy Farms

open access: yesRemote Sensing, 2023
Systematic measurement of pasture biomass (kg DM/ha) is crucial for optimising pasture utilisation and increasing dairy farm profitability. On-farm pasture monitoring can be conducted using various sensors, but calibrations are necessary to convert the ...

Estimation of pasture dry matter: comparative study between Rising Plate Meter and Grassmaster probe [PDF]

open access: yes
This study evaluated two expedient electronic sensors: a rising plate meter (RPM), and a “Grassmaster II” capacitance probe (GMII) to estimate pasture dry matter (DM, kg/ha).

POTENTIAL OF NON-CALIBRATED UAV-BASED RGB IMAGERY FOR FORAGE MONITORING: CASE STUDY AT THE RENGEN LONG-TERM GRASSLAND EXPERIMENT (RGE), GERMANY [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Forage monitoring in grassland is an important task to support management decisions. Spatial data on (i) yield,(ii) quality, and (iii) floristic composition are of interest.

The Influence of Rotational Length, along with Pre- and Post-Grazing Measures on Nutritional Composition of Pasture during Winter and Spring on New Zealand Dairy Farms

open access: yesAnimals, 2022
The quality of ryegrass–clover pasture was investigated between August (winter: start of calving) and November (spring: end of breeding) on pasture-based dairy farms (>85% of total feed from pasture) that had short (n = 2, Farms A and B; winter ~30 days,

An evaluation of the rising plate meter to predict forage biomass in Ontario mixed species perennial pastures [PDF]

open access: yes, 2023
The rising plate meter (RPM) is a tool used for pasture biomass (PB) estimation. The goal of this study was to determine if the RPM can be used to estimate pasture biomass in complex mixed-species perennial pastures of Ontario, and to establish an ...

Estimating Plant Pasture Biomass and Quality from UAV Imaging across Queensland’s Rangelands

open access: yesAgriEngineering, 2020
The aim of this research was to test recent developments in the use of Remotely Piloted Aircraft Systems or Unmanned Aerial Vehicles (UAV)/drones to map both pasture quantity as biomass yield and pasture quality as the proportions of key pasture ...

Estimating Herbage Mass in Stargrass (\u3ci\u3eCynodon nlenfuensis\u3c/i\u3e var Nlenfuensis) Using Sward Surface Height and the Rising Plate Meter [PDF]

open access: yes, 2022
Estimation of herbage mass is necessary both in research and farm management. Methods for such estimations should be inexpensive, rapid and reliable.

The use of compressed height to estimate the yield of a differently fertilized meadow

open access: yesPlant, Soil and Environment, 2018
Monitoring of grassland dry matter yield (DMY) is important for the economy and ecosystem management, but it is a time-consuming process. Calculating the correlation between compressed height (CH) and DMY is a faster way to estimate DMY.

Practical use of the rising plate meter (RPM) on New Zealand dairy farms

open access: yesProceedings of the New Zealand Grassland Association, 2001
Herbage mass and rising plate meter (RPM) height was estimated using the RPM as part of a farmlet trial, at No. 2 Dairy, Dexcel Hamilton. Herbage mass estimations were collected over a 3-year period, from pre- and post-grazing and weekly farm walk estimates.
