Fighting explosives pollution with plants

Biologists at the University of York have taken an important step in making it possible to clean millions of hectares of land contaminated by explosives.

Bury weed problems with an occasional plough

Tossing topsoil around in Australia's often arid farming environment is not best practice, but modelling suggests an occasional turning of the soil can delay the rise of herbicide-resistant weeds.

Emerging weeds show resilience to herbicide treatments
