topsoil

Your perspective on topsoil is interesting, considering how nutrition in our food is on a downward trend.

Even if the land itself is un-arable, one could always do raised-bed gardening with fresh topsoil.

For example, Iowa has lost an estimated 10 inches of topsoil in the last 150 years.

In the United States articles have been bemoaning the loss of our topsoil since the 1930s.

For example, the American Plains used to have 10s of feet of rich topsoil built by natural processes over the years.

For anyone concerned about the environment or aninmal welfare, they should find pasture raised animals, which sequesters carbon as the topsoil grows.

Rainfall tends to be less frequent and harder, which washes away the dried-out topsoil.

We haven't depended on topsoil to fill our collective larder since those 1930s.

Can someone explain to me where all of the eroded topsoil goes?

All of your nice topsoil banished beneath a rocky substrate.

Under that topsoil is meters of subsoil before the bedrock.

It is not just the climate, as previously mentioned, or the access to fresh water sources, it is also the fertility and durability of the topsoil.

Most ecologists will disagree with your assessment that Topsoil is "irrelevant".

Aside from the carbon sequestration aspect, "burying" charred biomass is very interesting from a standpoint of improving soil quality, as mentioned briefly in the article--though it's not really burying so much as churning it into the topsoil.

Topsoil used to be the big thing, before ammonia fertilizer.

Topsoil became irrelevant to farming decades ago.
