[Terrapreta] Nutrient adsorbtion by fresh charcoal

[Edward Someus]

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?
