If you dig a hole, you can see the process of soil production. Bedrock is broken up. Frost and weathering break it into smaller and smaller particles, such as boulders, then rocks, then gravel, then sand, then clay or silt. At the same time, organic matter at the surface is decomposing and getting mixed into the mineral matter. The closer to the surface, the more organic matter there is. In the hole you dug, you can often see distinct layers. At the surface is the O horizon, all organic. Then comes the A horizon, topsoil, high in organic matter. Below that is the B horizon, mineral subsoil. And so on down.

The soil you buy at a garden center might be "made", though, by mixing compost (organic) with sand (inorganic).

There are people who buy land, and strip the soil off for sale but much are from construction sites. Look into the history of Boston, much of Boston's forefathers were stripping the soil off their land for sale hence the geography of Boston changed over time.

Soil is complex and living, it not only includes inert materials but it contains organic matter as well. The most important component is the microbe and fungal population in soil. We do make our own soil but we tend to go overboard on the organic material through compost and mulch. The soil you buy at the gardening centers tend either to be all compost and mulch or all mineral earth.

When you search a new pit, you can observe the process regarding earth creation. Bedrock is usually separated. Frost along with weathering break the item in scaled-down along with scaled-down debris, You'll find people who buy terrain, along with reel this earth away for sale but significantly are generally coming from structure web-sites.

Without soil all living things apart from humans would be dead also animal carnivores because they prey on herbivores and herbivores need plants and plants need soil so animal carnivores would die out from hunger and from us killing them for food as we already do

Hi, I would like to know a few things about soil.

So first off, can soil be made? like can a farm somehow generate soil through some deliberate natural process?

Also, how do firms that sell soil get so much supply? Like consider gardening centers, or places like Bunnings warehouse, if your in Australia, which sell a great amount of soil for gardening purposes. I mean, if they have a set of land, do they actually take the soil from the Earth (and soon run out of supply), or do they somehow produce it?

I would really appreciate it if someone could answer this, also if you could answer it can you provide a website, because i would like to research it in more detail (its for a university assignment)

Thank you so much if you can help!
