Using Aquaponic Water as a Sustainable Fertiliser in Hydroponic Systems
Researchers from the University of Illinois investigated the use of aquaponics wastewater as a growth medium for lettuce in hydroponic systems.
In the study, published in the open-access journal Agriculture, researchers investigate using wastewater as a sustainable liquid fertiliser to support alternative ways to increase crop production.
The researchers sealed buttercrunch lettuce seeds in Ziplock bags along with paper towels saturated with the wastewater samples as well as two controls. The study aimed to investigate if wastewater could propagate the germination of lettuce seeds. Alternative methods of crop production are needed to sustain the increased demand for food caused by the increased global population.
