Biologists at Oldenburg University's Botanical Garden are researching ways of cultivating potted plants while conserving resources. Among other things, they cover soil of potted plants with microclover to protect water in the soil from evaporation. Water consumption during the cultivation of potted plants is thus reduced. In order to confirm or disprove the positive water saving effect of microclover soil cover, it is necessary to evaluate effects of this type of soil cover. As it turns out, the evaluation is a great challenge that the Botanical Garden's Biologists, the Software Engineering Department and the Systems Software and Distributed Systems Department are facing with an adaption of the environmental information system Guerilla Sensing.
