Farmers heat the orchard with burning oil.
Several shots of the orchard with blossomed trees. A man twisting something in his hand. Close up shots of different thermometers attached to walls - they are to keep farmers informed so they can prevent freezing. One of the thermometers has an alarm which is activated at low temperature.
Several shots of the oil storage tank, a tractor with a large oil storage. Oil is placed into containers placed between the lanes of fruits. Oil is then lit at night to heat the trees. Several night shots of lines of burning containers. Several shots of the orchard in the morning.
