Abstract
The possibility of remote sensing for precision management of grassland resources through the collection of site specific data detailing vegetation and soil conditions, has been advocated during the previous 40 years. Farmers need such information at early growth stages for optimizing fertilizer supply. In this review, we discuss the role of remote sensing in precision grassland management, putting emphasis on advances made in the last two decades. We describe the use of hyperspectral sensors, application of GPS, and the use of newly developed sensing devices that monitor livestock grazing behavior.
