Regardless of what Wikipedia says, fertilizer
burn with organic fertilizers comes from the pH raising effects of

You will never get the answer to "How do you know this?" David. He
has already re-framed his faux pas to "facts" he can weasel
word .....so down the rabbit hole he goes, again

Fertiliser burn is caused by high concentrations of soluble salts,
typically this is nitrogen salts because they are found in most
fertilisers and they are very soluble but you could get the same from
say potassium salts.


David,
sorry to have to use this wacko's post to reply to an old discussion
about whether only salts from commercial chemical fertilizers can burn
plant roots, or whether they can be burned by ammonia from decomposing
proteins as well. I was rummaging around old "postings", and found this.

It is part of an ancient discussion that Fran and I had about the merits
of fresh vs. aged organic fertilizers (poop).

The Rodale book of composting*By Deborah L. Martin, Grace Gershuny

I have found the Rodale books are good ones so what it said made sense
to me.

It says of fresh vs rotted/aged manure that:
i) in the composting process, manure can lose up to half it's moisture
content and thus concentrate nutrients
ii) nitrogen in composted manure is fixed whereas in fresh, it's soluble
iii) solubility of P and K is greater in composted manure
and on P.125 it says

that "when manure is added directly to the soil, it
generally releases highly soluble nitrates that behave similarly to
chemical fertilisers,

** as well as ammonia, which can burn plant roots and interfere with
seed germination." **

I would have liked to taken the credit for finding this quote, but we
can't know or remember everything, and that is why we are here, to get a
little help from our friends ;O)

Thank you, Fran.
