What you have there  is evidence of incompetence, stupidity
  and ignorance and nothing more.
Of course the article is almost 50 years old so you can't
blame them too much for being 50 years behind in their
knowledge of soil science. The farming practices back
then were the real roots of the incompetence (pun intended)

Plants don't exude the valuable carbohydrates from
photosynthesis unless they're getting something
equally valuable in return. Typically with conventional
agricultural practices roots do not exude much
because the organisms that the exudation feed
don't exist in the soil. Plants don't
expend the energy if it is wasted.

The whole purpose of the expanding practice of
no-till combined with cover crops and root diversity
is to maximize humification fed by plant root exudation.
Here is a more modern take on root exudation
http://tinyurl.com/h2dod2s

Notice on page 6 it says:
Rhizodeposition - 20-60% photosynthate released into rhizosphere 
(depending on plant)

So if half the energy captured from the sun
is feeding the organisms that create humus
you can deliver a lot of carbon to the soil.

when you have humus you have carbon in a form that is
stable and can last for decades or even centuries.
Decayed plants are beneficial to soil health but
in that form most of the carbon is oxidized and
ends up back in the atmosphere as cO2 relatively
quickly.
