Remote sensing methods
In agricultural research, different sensors are used at various levels. We test and optimise the use and evaluation of sensors and carrier platforms for substance-flow research applications. Stationary cameras provide information on crop development at high temporal resolution. Aerial photographs enable detailed evaluation of plot trials or improved fertiliser application. Spectrometer measurements help us derive a variety of properties from a single analysis.
Site-specific fertilisation and precision farming
Projects focusing on site-appropriate fertilisation aim to harness the capacities of remote sensing to optimise fertiliser application. These applications have the potential to increase nutrient use efficiency and reduce losses to the environment. We develop standards and user guidelines and test them under practical conditions to promote the use of remote-sensing methods in agriculture.
Remote sensing can be used in various applications for environmental assessment. Drone and satellite imaging, for example, enable the acquisition of regional and national information. We develop methodologies (algorithms) for evaluating various remote-sensing products, among others to detect anomalies (diseases and nutritional disorders) in the field, quantify crop characteristics (crop canopy cover and biomass) or derive spatial information (land-use classification and fertiliser application maps).
