Biochar binds DDT, field experiment image 1 (IMAGE)
Caption
The researchers dug out soil, put it in piles and mixed biochar into half of them. They then set up 24 experimental plots and distributed the soil piles to them in a randomized experiment. The results later showed that the amount of DDT taken up by earthworms in the soil decreased by an average of 50 per cent when the soil had been mixed with biochar.
