Tim Horton has been cutting 40ha of Siberia winter barley in Gloucestershire. He said results were moderate on the lightest soils, but better on the heavier and chalky fields.

He hoped remaining barley yields would hold well, as long as the temperature did not rise above 30 degrees again, which caused some crops to go off on the lighter soil.

He said: “I think the barley has slightly more potential than last year, but crops on the thinner soils are struggling.”

Mr Horton also had concerns for winter wheat yields on lighter soils due to the dry weather, but he expected them to be fully ripe within a month.

Oilseed rape had been dessicated with glyphosate, which he expected to be ready within three weeks.
