PASTURES FROM SPACE – VALIDATION OF PREDICTIONS OF PASTURE GROWTH RATES

摘要

To improve the sustainability of Australian agriculture, new technologies are needed to monitor and assist management decisions in grazing systems. Pasture growth rate (PGR) is a critical driver, however few farmers can find the time and resources toassess PGR on all farm paddocks. A deterministic model to estimate PGR in a GIS environment has been developed by the Pastures from Space consortium (Mata et al. 2004). This paper reports the validation of the model using actual PGR, and following improvement to satellite imagery.
