On a blustery spring day, Thomas Gent is walking through a field of winter wheat on his family’s farm, which straddles the Cambridgeshire and Lincolnshire border. Some of the green shoots reach his knees, while the ground between the plants is covered with clover.
Sinking a spade into the soil, Gent grins as he points to the freshly dug clod of earth on the blade. “Look at the root structure,” he says. “It rained 20mm last night. The water has drained down because the soil structure is in the right format.”
