Four conversations today - first, I'll meet David Wright, the Chief Executive of Ecometric, to find out about how exactly soil carbon is measured - then after that I'll talk to Chris D'Agorne from Life to Land about an analysis that shows that the non-native sycamore is now the UK's third most populous tree species. Later I'll discuss the benefits of having more trees on farms with Huw Evans from Three Pools, and we'll round up the programme with a conversation about the Westminster government's proposals for mandatory method of production labelling with Peter Stevenson and Catherine Jadav from Compassion in World Farming.
