| | | Re: Terra preta Ich köntte versuchen diese Deutsche Texte zu übersetzen, aber auf die Beitrage mit Untertitlung habe ich bisher wenig Respons bekommen. I could try to post English translations of these German newpaper clippings, but so far I have very few reactions on my postings with subtitles.
Die Deutsche Texte sagen auch nicht viel mehr als wass schon in das Englische forum ûber Terra preta gesagt ist. Übersetzung wäre also nur wichtig für Leute die ihr Deutsch üben wollen. Und die Texte sind deutlich nicht für Anfänger. The German newspaper articles don't provide much more than what is already said in the English forum about Terra preta. Translation would only be important for people who want to practice ther German. And the texts are clearly not intended for beginners (when it comes to German).

I was just posting some German links on Terra preta. Here is another although this abstract is in English, the publication is German http://www.springerlink.com/content/ch88m96jtrfrj4gk/ Quote: The 'Terra Preta' phenomenon: a model for sustainable agriculture in the humid tropics

Abstract
Many soils of the lowland humid tropics are thought to be too infertile to support sustainable agriculture. However, there is strong evidence that permanent or semi-permanent agriculture can itself create sustainably fertile soils known as 'Terra Preta' soils.
These soils not only contain higher concentrations of nutrients such as nitrogen, phosphorus, potassium and calcium, but also greater amounts of stable soil organic matter.
Frequent findings of charcoal and highly aromatic humic substances suggest that residues of incomplete combustion of organic material (black carbon) are a key factor in the persistence of soil organic matter in these soils.
Our investigations showed that 'Terra Preta' soils contained up to 70 times more black carbon than the surrounding soils.
Due to its polycyclic aromatic structure, black carbon is chemically and microbially stable and persists in the environment over centuries. Oxidation during this time produces carboxylic groups on the edges of the aromatic backbone, which increases its nutrient-holding capacity.
We conclude that black carbon can act as a significant carbon sink and is a key factor for sustainable and fertile soils, especially in the humid tropics

Since this is the German forum, here is the German translation of the message above. Michael, mit dieser Link bekomm ich nur das kurze Englishe bericht. Weiter klicken auf die Links in dieses Bericht gibt mir nur eine Meldund "Seite nicht gefunden". Ich versuche uber meine Kontakte das Original zu bekommen, aber ich kann leider nichts versprechen

Description
The extraordinary fertility of manmade Terra Preta soils in the Brazilian Amazon provided the incentive to study the effects of soil charcoal amendments on soil fertility, nutrient cycling, and soil biology.
The existence of Terra Preta suggests that tropical soils, which are notorious for being infertile, can be greatly improved. The agricultural produces charcoal out of fallow vegetation instead of converting it to carbon dioxide through burning. Slash and char improves soil quality by transferring organic carbon into recalcitrant soil organic matter pools. This newly described agricultural practice has important implications for the earth’s carbon budget and sustainability in tropical agriculture.
