Short summary
Proximal sensors can assist in managing feed in livestock production systems but raw data needs calibration to biophysical values such as biomass and ground cover. Our pilot project monitored tropical pastures for 18 months using digital cameras, multispectral sensors, soil moisture sensors, and field observations. We developed stringent data cleaning rules that are applicable to other sensor projects. Proximal sensors were found to deliver continual and timely pasture data.
