Remote sensing technologies, including new drone technologies, are developing rapidly and emerging onto the marketplace. These technologies may provide grass quality and quantity information to support grassland management. This concept was developed and evaluated in a collaborative research project (GrassQ) across four EU countries. In regions where silage forms a significant portion of cow diet, the timing of the first and subsequent silage cuts is critical. Monitoring of sward quality parameters, height and dry matter (DM), by drones/satellites can be used to identify the optimum harvest times. Alternatively, where pasture grazing systems are common, monitoring of herbage yield/mass is critical to optimise precise herbage allocation to the herd. Drone and satellite technologies were used to capture this grass yield and quality over two growing seasons in Finland, Ireland, Denmark and Switzerland. A cloud based service and mobile application, allowing access and interpretation of these data was developed as a grassland management support tool. The prototype GrassQ management support system, incorporating drone and satellite data, analysis, modelling and visualisation tools, hosted on the cloud and application to provide Grassland information management service were presented to farmers in the different countries to evaluate in terms of usefulness, importance and robustness. This paper reports on the evaluation. Generally, satellite technologies were considered in a positive light, having the ability to streamline grassland management at farm level. Drone technology was considered as having potential to provide good yield estimates, while the application had potential to provide easy access to grassland management support information.
