At the beginning of the experiment, participants are presented with directions (short instructions, see download) on how to conduct the experiment. These include a description of the basic conditions, which must be accounted for in order to complete the experiment.
The field experiment, which could be carried out, for example, at the BOKU trial site in Groß-Enzersdorf (or at any other location with various homogenous plant populations), should make the influence of plant populations on the microclimate and water supply clear. The experiment can be conducted over a short period (snapshot, difference between plant populations) or over a longer period of time (illustration of changes over time, such as day-night cycles, seasonal differences).
- Identifying and understanding the causes (to be explained by the energy and water balance) of the water supply and water-use efficiency, as well as the micro-climate and growth conditions of plant populations.
- Understanding and personal estimation of possibilities to optimize micro-climatic conditions and water usage of plant populations.
Conducting the experiment with detailed instructions
Level 1: Theoretical introduction (1 hour)
Level 2: Location selection and measurement set-up (2 hours)
Level 3: Conducting measurements and data collection (Duration: 2 experiments to choose from: < 1day; > 1day)
Level 4: Analyzing and interpreting the data (>2 hours)
The measurements are conducted with the help of the following available pieces of equipment from the equipment pool:
- Base weather station (including net radiometer and soil heat flow sensors)
- Up to 12 mini-stations (micro-climate in plant population: soil and air temperature, air humidity, soil moisture)
- Communication software to connect to measuring station: (requirement: personal laptop)
- Thermal imaging camera (optional)
