Like forests and oceans, soils also capture carbon, through the vegetable matter that decomposes in them.Nicolas Denieul plants his spade in the ground and turns over a clod of soil to reveal a mass of earthworms seething around plant roots — fat ones and thin ones, delicate translucent violet and dark b French farmer Nicolas Denieul shows earthworms in a wheat field in Piace, France.

Back then his spade met smooth earth, empty of worms, insects and the other small organisms that signify a healthy soil.France’s agriculture ministry launched an international research programme on the subject this year, which 40 countries signed up to at the ongoing UN climate talks in Paris.“That is magnificent.4 percent a year in the level of carbon in soils would make it possible to stop the current growth of carbon dioxide — a major greenhouse gas — in the atmosphere, according to the French National Institute for Agricultural Research (Inra).End of ploughing On top of urbanisation and deforestation, soils around the world have suffered as a result of the intensification of farming since World War II. “We have massacred the soil” with bigger combine harvesters, deeper ploughing and chemical fertilisers and pesticides,” Mr Denieul said.An increase of 0
