Healthy soil and sustainable growing

[Mike <mike.lists@mlxvi.org>]

By opening up the subsoil, just beneath the topsoil each time, to air and water Yeoman claims (and this is supported by a person I spoke to who has experience with this) that the roots of the pasture plants will reach down and fill the gaps as they are let to grow tall. By hard grazing (or mowing) the plants no longer need all of the roots and so the deeper roots die off. Hey presto, new organic matter under the existing topsoil.

Rinse and repeat.

It is important to note that only a small increment is performed each time.

I will admit that some of Allan Yeoman's ideas are a bit weird to me, but this one idea of his father's seems to be well accepted in some circles.

D´Coda,

 

The statements on this site are misleading. Probably not without intent.

There is no way of creating 3 to 6 inches of topsoil in a year, especially not

on grazing land. What is originally meant is that you use a subsoiler (a plough

that opens up the subsoil without turning the soil) such as the Keyline Subsoiler

manufactured by the Yeomans brother in Australia to rip open your soil to a

depth of 18 to 24 inches, and that if you repeat this twice a year for a duration

of 3 years this will somehow transform the top 18 inches of your soil into

topsoil, hence 6 inches in a year. The term topsoil is not very precise and

can be used to mean pretty much anything to want it to. However, what is

clear is that the above method does not create any new topsoil, black dirt like

compost or even humus, which can only be achieved by new organic matter.

 

Subsoilers are normally used for opening up compacted subsoil after

years of shallow cultivation. The Yeomans on the other hand target their

products at grazing land. I don’t know why this should be compacted in the

first place, but farmers are reported to be satisfied with the system.

 

Regarding your second point, there is nothing that will reduce CO2 in the

atmosphere to pre-industrial levels. I would favour tax breaks for farmer

converting to organic no-till using cover crops and for landowners to pay for

for reforestation or to simply leave their land with whatever native vegetation

it happens to have. I certainly would not trust assorted commercial parties

and whiz kids with get rich business quick business ideas. They say they

want to set up a non-profit organisation, I take this to mean that there are

no profits left after varies parties have skimmed off their part.

Two claims made here:
1. That there are records of creating 3-6 inches of topsoil in a year -
using Yeomans sub-plowers and Savory style intensive grazing.
2. That a huge proportion of the excess of carbon in the atmosphere is soil
and that by simply adding "1.6% organic matter to the world's ag. soils, we
could reduce C02 to pre-industrial levels"

Here's a clip from an upcoming TV show about this:

Since I can't check this out myself, I hope you all will and make your
comments....is all this for real, what do you think? (And if anyone would be
so kind as to post some "how to" type info here, much appreciated.)
