This week the first Trade Deals made since the UK left the EU came into force - with Australia and New Zealand. Some farmers are concerned the deals will lead to the UK being flooded with cheaper imported meat. We hear from the Agriculture and Horticulture Development Board (AHDB) which has been using modelling developed by Harper Adams and Exeter Universities to asses the potential impact on UK agriculture. For the first time the UK Government has given permission for commercial drones to be used for the aerial spraying of weeds with pesticides. At this stage it will only be used on railway bridges where working at height can be dangerous. But using drones in British Agriculture is gathering pace, as our reporter Sarah Falkingham has been finding out. And a question from a listener about the porcine products in her medicine leads the team to take a look at how products reared and grown on farms are used in the pharmaceutical industry.
