Researching biochar as a soil additive to increase profits, yields
Researchers at the University of Arkansas Pine Bluff Agricultural Research Station have found ways to solve two major challenges related to soil contamination and sub-optimal growth through the use of biochar – charcoal made from biomass.
Biochar products can be used as a sustainable soil additive to capture agricultural chemicals. The product is added through conventional tillage and helps degrade pesticides, antibiotics and other undesired chemicals during agricultural production.
The research led to better understanding of the binding structure of contaminants and how they diminish the ecotoxic effects on plants and microorganisms. It also demonstrated the potential for biochar to promote plant growth and act as a carbon sink.
The research could help redefine best management practices in agriculture by advocating the use of biochar in problem soils. It presents a potential cost-effective solution for farmers who deal with contaminated soils.
