The University of Southern Denmark has announced NutriCycle, a three-year collaboration with Kiel University and horticultural partners to develop an automated analyser for greenhouse irrigation water. The project has a budget above €1.8 million, including approximately €1.2 million from Interreg Deutschland–Danmark.

The proposed device will examine small water samples using microfluidics. Its purpose is to identify individual nutrients, enabling growers to replenish particular ingredients instead of replacing an entire recirculating solution based mainly on overall salt concentration.

Partners include HortiAdvice, VandCenter Syd and NPZ Innovation. Work will begin with loss assessments and measurement development before a prototype is tested at NPZ Innovation in Germany. The announcement describes a development programme; it does not report a commercially validated sensor or measured reductions in fertiliser discharge.
