Short project description

This project is linked to ongoing research at Aarhus University on practical sensor-supported nutrient management in recirculating greenhouse systems. The aim is to improve irrigation and fertilisation strategies under commercial greenhouse conditions, particularly in peat-reduced growing media where water and nutrient dynamics are often difficult to interpret.

The student will work with controlled but practice-oriented greenhouse experiments, where contrasting substrates and management conditions are used to study nutrient behaviour in the root zone. A central focus will be how sensor signals and flush measurements can support better understanding and management of nutrient dynamics.

Depending on the student’s interests, the project can focus on substrate effects on water and nutrient buffering, evaluation of simple greenhouse-compatible sensors, comparison of practical nutrient diagnostic methods, or development of decision-support principles for fertigation management.

The project offers hands-on experience with greenhouse experimentation, nutrient monitoring, data analysis and interpretation of plant–substrate–water interactions, with clear relevance for future commercial greenhouse production.
