A Government commissioned review of the problems with farm profitability, carried out by Baroness Batters, is due to be delivered to DEFRA soon. It comes at a difficult moment for the arable sector in particular. One of the UK's biggest farming companies, Velcourt, has recently given notice to a fifth of the landowners it works with, that it will either leave or restructure contracts following negotiations. Velcourt's Group Chief Executive, Nick Shorter, tells Charlotte Smith that a painful period of adjustment will lie ahead as arable producers adapt to the harsh economic reality of life without subsidies. He says continuing to grow wheat and other crops at a loss will be unsustainable for individual farmers and for the wider industry, and there could be new business opportunities on unprofitable land.

As the land is gradually being replenished by autumn rain we meet the scientists measuring soil moisture using cosmic ray neutron technology.

And, continuing our look at tackling invasive species, how the distinctive buzz of the Asian Hornet could be key in tracking down its nests.
