We speak to the Environment Secretary about the government's new farming roadmap for England. It's 25 year plan and ministers say it'll give farmers the long-term clarity they need and access to the tools, technology,  skills and supply chains 'to innovate, invest and grow with confidence for generations to come.' We find out what farmers at the regenerative farming event Groundswell think of it, and discuss food security and global volatility. Experts argue that the UK can't have a 'business as usual' approach to growing food and food production should be a priority.

All week we're talking about soil. Maize has become a controversial crop in recent years, in part because of its potential to cause soil erosion. In Devon, an on-farm trial is underway to grow maize interspersed with strips of mixed plants known as a 'living mulch', to protect the soil.
