[Terrapreta] Nutrient adsorbtion by fresh charcoal

[Edward Someus]

Rich, 

Tks for response.  

Yes, in the past few decades, chemical fertilizers have come into widespread
use. This strong focus on chemical fertilizer use has meant that the soil
has tended to be regarded as an inert medium for plant roots, rather than as
a living biosphere in which the crop is only one of hundreds or thousands of
interacting species. However, it is now realized that in fields under
intensive monoculture which receive heavy applications of chemical
fertilizers alone, there is a slow decline in productivity. For P fertilizer
Cadmium and Uranium contamination became a high risk. 

Let us keep in touch.

Thank you for the contact. I am pleased to see your website and learn of
this very important project. It seems I am on a parallel track to your
groups' project mission and I have much yet to learn about conducting and
interpeting results such tests.


When they are completed your comments would be welcome. Note also this will
be my first set of soil analysis since setting up the project and these soil
tests will be just before I treat the entire set of plots with urea.
Standard timing at our farm.


The next soil tests will also be taken at time of lifting with a nursery
bare root lift/shaker in, most likely early November. Currently I am
undecided because of budget issues whether to conduct foliar analysis in
early fall (September). 


I  have looked at your website and mission. We also have been victim of
over-fertilization, over-liming and 50 years of dairy waste disposal by
previous farmer. We have not previously paid close attention to our soil
analysis and have continued to date to use high p and k fertilizer sold by
local farm supplier. Attached is analysis taken this spring at various
locations at our farm. It is samples take from various stages of our 2 year
bare-root production cycle. The east field tests (2343,2344) are from a new
section previously in  pasture but historically dosed regularily with liquid
dairy wastes. 


Attached is a table of soil analysis that I conducted at various points on
our 60 acre farm, early spring. Beyond our tests of charcoal per se I think
these tests will help me to come up with a soil fertility management plan.

Good morning Rich,
 
I would be very happy to receive your soil analysis for charcoal treatments.
 Thank you.
 
I am making bone charcoal test for different soil and climatic regions in
Europe (Israel, Italy, Germany, UK, The Netherlands and Hungary), usually
for test plant tomato and sweet pepper. I will have progress results by late
summer, published on my web page www.terrenum.net/protector
 
Tks

Hello Folke


In a few weeks I will be taking soil analysis of a set of charcoal
treatments I set up earlier this spring. I have two types of charcoal and
permutations with compost, fertilizer, controls in 28 plots approximately 14
feet long each.


So far the charcoal and treatments have been in place for 2 months. The soil
tests should tell us something about this question. Will probably have a
report for us by end of July.


Best Wishes 


Rich Haard

Nutrient adsorption by fresh charcoal
Submitted by Folkeg on Sat, 2007-04-21 08:33.
As I understand it, adding fresh charcoal to the soil would have an initial
effect of removing nutrients from the soil. After the sites are fillded up,
the typical 'Terra Preta' effect would add on.
Adding nutrients to the char previous to the addition to soil would
reduce/reverse this initial effect.
For example, adding urine.
Does anybody have any idea of the specific adsorption capacity for charcoal
on nutrients?
