David White farms 160ha on light land over chalk between Cambridge and Newmarket. He is in his sixth year of practising conservation agriculture – utilising no-till direct drilling into catch and cover crops. Going from full cultivation to 100% no till in a single step was a big change and along the way it has required, and continues to require, trialing different things to see what works best on his soils. He is co-founder of RTK Farming Ltd which provides repeatable 20mm accurate subscription correction signal for any brand of machine across England.
