We had a discussion on this very subject a few months ago in
sci.agriculture. Suffice to say that in practice, certainly in the UK,
this assumption is unjustified in practice IMHO. We can discuss this in
depth if you wish.

Who is Rohdale? How are they doing it? What is their criteria? What
crops?
With enough manure and no attacks of pests and diseases location then
vegetable crops can be grown with little difference between organic and
conventional. However it's as well to note some differences. One problem
is the mismatch of nutrients in organic manures. So growing potatoes on
a clay that liberates potassium is fine as you really only have to apply
enough manure to provide the nitrogen for the crop. Admittedly the high
nitrogen early in the season results in a lot of small potatoes rather
than a few big ones and so large peeling losses, but still. Try to grow
them on a non-potash liberating loam and you are in all sorts of
trouble. The correct amount of potash results in a massive overdose of
nitrogen.
Of course if you get blight then the crop is a write-off.
If you get aphids you are in trouble.
If you get Colorado beetle you are in serious trouble.
etc. etc.
For cereals there are too many problems unless we are talking extensive.
I would define extensive these days as less than 2T/ac. Not least the
country doesn't provide remotely enough manure to do it.
After all farmers don't waste the manure they produce now and there
isn't remotely enough sh*t to go round. We use 2,000,000 gallons of
sewage sludge here and to supply all the nitrogen we need would require
all the sewage from a town of 30,000 and that's counting the offerings
of our 200 cow herd. We are only a medium sized UK farm too. It ain't
possible countrywide. So, someone is going to have to starve. Lots of
people are going to starve in a yellow rust year. Nature is neither
pernicious nor benign, it just simply doesn't care.

Well, my farm *was* farmed semi-organically and you wouldn't have
described it then as 'hearty land'. You would have described it as low
fertility, low soil OM, low yielding, poorly structured and generally
poor. Bag fertiliser over many years increased yields, and thus the
return of OM to the soil, to the extent that the soil is now in good
condition. One indicator is that moles, who eat earthworms, were unknown
then yet are nowadays a plague. So the earthworms prefer it too. Nature
can be irritating to those with pre-conceived views, can't it? :-)

Oh, I apologise if you found my reply 'nasty and inflammatory'. Be
warned though that in many groups I am considered wimpy and excessively
polite. My route to this thread is via .agriculture so it's hard to
remember that there are those posting whose knowledge of agriculture may
be limited. I don't agree with you, but that doesn't mean that my
comments were intended in a nasty fashion. Loosen up a little and have
an open mind. It's an interesting subject and worthy of discussion.

And why not?
