Agriculture students at Kingston Maurward college have been spreading manure to help keep a life-saving service airborne.
The second-year national diploma students spread 20ha, then ploughed and drilled maize to raise more than £1500 for Dorset & Somerset Air Ambulance.
As part of their fund-raising challenge, 10 of the students had also pulled a tractor a quarter a mile through Dorchester town centre.
"Safety is a big issue for farmers, who, as we know, often work in remote and isolated places," says student Izzie Place.
"With no motorway in Dorset, it's such a valuable service, so we felt it was the right charity to support."
The students were able to complete their muck spreading challenge within only 10 hours.
