Roughly 3% of England’s agricultural holdings (3,145) and 2% of England’s total farmed area (223,000 hectares) are in Sussex.
Will, 42, who grew up on the family farm, works approximately 1,500 acres of them – divided between predominantly arable under a mix of owned, rented and shared farming agreements.
He also has a small beef herd.
He said: “Food security is one of the most important priorities facing the UK and it is madness for a policy to insist on taking productive land away from this aim.”
The farmer now fears for the security of his business if eco schemes are forced through at the expense of his ability to produce crops.

His criticism chimes with thousands of Welsh farmers who protested outside the Senedd last month, with thousands of wellies placed on the steps of the Parliament building in Cardiff.
It also comes after a Welsh government report warned its controversial Sustainable Farming Scheme could see £200million lost from the sector.
Will said: “Environmental benefits can be shown alongside feeding the nation, but it is vital that farmers are allowed to farm or they will be forced out of business.”
He went on to warn against the UK market becoming flooded with poor quality produce from aboard as a result of British producers being hit by a loss of land.
He said: “British farmers produce to the best standards in the world so we should not be relying on imports from countries that cannot match our high assurance qualities.”
