Some farmers are selling directly to the public

The poll will find out what farmers are doing to beat the downturn in the industry in recent years.

It will ask questions on diversification, direct dealings with the public and the amount of female involvement in the business.

Many farmers in the region now run bed and breakfast to supplement incomes.

New optimism

One farm in Cornwall is being hailed as an example of what can be achieved.

Kestle Farm, near Mevagissey, sells produce directly to the public, taking advantage of visitors to the neighbouring Lost Gardens of Heligan.

Brothers Richard and Terry Lobb, who run the farm, rear their own stock and grow animal feed on the farm.

Their farm shop sells meat from the farm and other locally-produced goods.

The brothers say it will be some time before they can properly assess how the business is developing, but say there is new hope and optimism.

Terry Lobb said: "We're hoping it will enable us to stay here on the farm and that our sons and daughters, if they wish, can take over from us one day."
