Biochar reduces the risks of DDT-contaminated soil

DDT soil pollution is still a major problem in many parts of the world. Researchers have developed a new method to manage ecological risks from the toxin by binding it with biochar. When they mixed biochar into contaminated soil at a former tree nursery, DDT uptake by earthworms in the soil was halved. This method may enable the growing of certain crops on land that is currently considered unusable due to the environmental risks.
