If you stop and think about it, every material comes from the ground or air. I once took an Environmental Science class (needed a science class for my CISS degree), and the instructor told us that there is really no water shortage, and aside from water that we send to outer space, the same amount of water that was on this earth many years ago is still here, but simply changes form (all of it is either a liquid, solid or vapor and is constantly changing form). Makes a whole lot of sense. When you stop and think about it, one can say this about most everything. I still say that the earth can take about anything we humans dish out, and the earth will be here when we are long gone, and given enough time, all that fly ash is like a lot of other materials we re-deposit back to the earth. We spend/waste huge amount of effort on things that really do not matter in the grand scheme of things (coal burning, proper disposal of fly ash, mixing ethanol with our fuels, Bruce Jenner to name a few). May take a while, but it will all return to where it came from, but I doubt we are here to see it. Something to ponder.

Potatoes were grown for sale and oats were grown to be used for cattle and horse feeding. Up to about 1958 the dairy cows were fed hay with some turnips and after that grass silage was the main winter feed. That same year was the last in which flax was grown on the farm. Flax provided the fibre which w
