Biochar as Substrate for Hydroponic Tomatoes

tomatoes USDA photoAs the use of soilless, hydroponic growing methods becomes more prevalent among crop producers, researchers are looking for new materials that can help growers save money, produce healthy plants and contribute to sustainable practices. The authors of a study in HortScience say that biochar, a charcoal-like material produced by heating biomass in the absence of oxygen, can help “close the loop” when used as a substrate for soilless, hydroponic tomato production. “This method could provide growers with a cost-effective and environmentally responsible green-waste disposal method, and supplement substrate, fertilizer and energy requirements,” said the study’s corresponding author Jason Wargent.
