Module 1 – Ecotron

In collaboration with UGT Umwelt-Geräte-Technik (UGT), we have developed two types of EcoLab 500 prototypes based on UGT’s extensive experience with building advanced mesocosms. The so-called standard model provides a full range of control and above- and below-ground sensors, with air temperature controlled via ambient room conditions. The climate-controlled model allows for precise atmosphere temperature and humidity control per unit. A battery of 28 standard units have been ordered and installed in two experimental areas, offering higher experimental flexibility. The 8 temperature-controlled EcoLab 500 units have been installed in a separate experimental area.

In total, the NPEC Ecotron facility at Utrecht University offers a wide range of experimental flexibility and throughput, allowing researchers to precisely track above and below-ground parameters at a scale and complexity level that mimics real-life conditions.

In the precision mesocosm-level Ecotron, researchers can simulate agricultural and natural ecosystems. They can mimic the complexity of the real world in closed systems in which all aspects can be controlled and measured. Ecotrons provide ideal facilities for studying above- and below-ground processes to discover which combinations of crops work well together, what the best conditions are for ensuring efficient use of nutrients and preserving soil fertility, and how plants interact with other plants and soil life. Each unit provides a full range of control over the experimental conditions, such as independent control of soil and atmospheric temperature and humidity, artificial daylight, rain, weight, and automatic water sampling. RGB cameras allow tracking of the above and below-ground plant development.
