Kelp biochar: a potential plant substrate for freshwater aquaponics
Published:May 4, 2017
Summary
At the University of New Brunswick in Canada, researchers have developed a pilot-scale aquaponics system to select plants that are best adapted to efficiently recapture nutrients from salmon hatchery effluents. Along the way they’ve developed a novel substrate on which to grow the plants. In many aquaponic systems, it is common to use a substrate such as foam, coconut coir, rock-wool or ex...
