Healthy soil and sustainable growing

["E. E. Mitchamore Jr" <emitch@att.net>]

If I may be so bold as to double-emphasize a couple of Harvey's comments (often attributed to Joel Salatin, but also stated by Alan Savory):

 

"In order to re-establish balance between top growth and root mass after
being grazed, perennial grasses and legumes that have co-evolved with
grazing animals shed root hairs".

 

And,

 

"Also, when the roots of the cover crops die, they
decay (are consumed in place, undisturbed, by microbes) and like the
worms open channels deep into the soil".

 

Put these two thoughts together, and you have the concept that there is approximately as much organic matter contained in the root system of a plant as in the top growth.  This (root) organic matter is widely distributed through the soil, and capable of generating humus at least as well as anything we do on the surface.

Just to reinforce Dieter's excellent point here: It is not sufficient
simply to stop plowing, or even to use mulches. To my mind an essential
part of no-till is the regular growing of cover crops. The cover crops
encourage earthworms and other soil life, both of which change soil
conditions profoundly. Also, when the roots of the cover crops die, they
decay (are consumed in place, undisturbed, by microbes) and like the
worms open channels deep into the soil. All these life and death
activities help loosen the soil at depth without the need of shaped steel.
