what are the big mounds of stuff on farms that are covered in tyres?

Answer 1

Silage -- feed for the cows and other animals. I've always heard that the tires keep it from freezing, since they are black and absorb heat, but below they give another reason!

"Silage is fermented, high-moisture forage to be fed to ruminants, cud-chewing animals like cattle and sheep. It is fermented and stored, a process called ensilage. Silage is most often made from grass crops, including maize or sorghum. Silage is made from the entire plant, not just the grain."

"Piles should always be covered as soon as possible after the pile is built. A 6-mil black plastic sheet should be pulled over the pile and tightly sealed along the sides by piling sand or limestone along the edge. Tires (touching each other) are good for holding plastic tightly against the top surface of the pile. This helps to prevent silage spoilage due to air exposure. "

Answer 2

In Australia, this is called "silage". it's the excess hay farmers harvest from their fields - its basically a feed source for cows when there's not a lot of natural hay / grass for them to eat.

don't go near it when they uncover it! the grass ferments under the tyres and plastic that they cover it with and it STINKS! A lot!!

hehe...

hope this helps!

It is silage, the tires are just a cheap way to hold down the cover on windy days
