Can I ask for a bit of help from my friends here?

39. It would be phenomenal to get that much new topsoil :)

I had to do a little calculation on what that half-inch means in terms of volume the rest of us can understand.

First off, 100 acres converts to 484,000 square yards. Now, I assume a one-inch layer (will divide by half later) to make it easier to understand. Most topsoil or mulch, or compost in the US is bought and sold in dump-truck or pickup truck-sized loads. That means it's sold by the cubic yard. So, it would take thirty-six square yards at one-inch thickness to equal one cubic yard in volume. The "average" dump-truck carries 16 cubic yards by volume. Thus:

100 acres = 484,000 sq.yds. = 13,444.4 cubic yards / 2 = 421 avg. dump-truck loads!

Those sheep better produce a lot of caca!

You're welcome for the links. I often research topics I enjoy learning about, and then saving what I find. I never know when someone will come along needing exactly that information.And if you don't have the books "The Secret Life of Plants" and "Secrets of the Soil" at least get the second one. More information than I could ever regurgitate

I was looking at that online-library link last night as saw their section for books on soil microbiology. Very important stuff, as are worms. But, I'm sure you know about much of that already. I would expect any farmer, no matter the size of their operation, to be well-educated about the soil and everything else associated. You certainly know quite a bit about the plants and seeds
