This is a film which shows how vacuum silage is made on a farm in North Yorkshire, using interties throughout to explain the various processes. The film opens with a shot of a grassy field. Title - Sealomatle Storage Systems Ltd Present 'Waste not Want Not'. Title - A film to show how Vacuum silage is made. Title - Copyright reserved. Title - Grass is acknowledged to be the cheapest and most efficient food for cattle and sheep, but hitherto the problem has been how to store it for winter use without considerable wastage and loss of food potential. The losses incurred by ordinary silage and haymaking methods are seldom less than 35% and in wet weather hay crops can be completely lost. This film shows how grass can be conserved for winter feeding and still retain nearly all its original goodness. Title - The vacuum silage method can conserve over 95% of the original food value and yet this amazing efficiency is achieved with extremely low costs without any expensive machinery or equipment and it works equally well with large or small quantities. A cow feeds on hay in a small enclosure and there is then a panning shot of a barn where a herd of cows are resting. Two farmers, wearing flat caps and slacks, unroll a length of shiny, black material, which is stretched out to cover a wide square in the field. One farmer then scoops up earth into a bag. A shot then shows a bare patch of earth amongst a green field, and a farmer carries several sharp poles, knocking them into the earth in the corners of the field. Metal wire is then unravelled by the farmers, who set about fixing several lines across the bare patch between the poles - creating a criss-cross effect. A farmer drives hay a tractor with an attached trailer filled with hay into the bare area and unloads the hay onto the earth. Once the hay has been laid out evenly, another layer of black plastic sheeting goes across the top. Grass makes up the second tier, which is loaded by a tractor. As more and more grass is added, the second tier becomes a large mound and the farmers walk along the top unravelling another layer of plastic sheeting, which they attach a rubber tube to. The tube will pump out the air, thus forming the vacuum. A close up shows an engine connected to a shaft, which spins at a high rate. An expansive view shows the silage storage site, which is now a large mound black mound positioned by several farm buildings. An unseen farmer then creates a small slit in the black plastic surface using a knife, taping the slit over with a piece of black tape. Another expansive view captures the silage mound with many white bags filled with earth placed on the surface to keep it weighed down. A farmer then steadily walks along the mound, before feeling the surface and stabbing it many times with a knife. The air from the tubes is turned off, and the engine with the rotating shaft comes to a halt. A farmer runs his hands along the surface taping up more areas with black tape. On a windy day, the black material from the top tier is removed, revealing the grass has now matured into hay. The farmers roll up the material as they go. A tractor then scoops up the hay and dumps it on another pile. The farmers then place the earth bags over the bottom tier of the silage storage.

The final shot shows the field with hay bales and a parked tractor. Title - The End.
