Register now


Invitation, Tuesday June 30, Zodiac Building, Room C0085

Dear colleague,
We are pleased to invite you to a symposium hosted by the Terra Preta Program of Wageningen University and partners on 30th June, 2015, 09.15-18.00 hrs, Zodiac building, Room C0085. We have an excellent selection of international speakers who will give talks ranging from the archaeology of Amazonia through to the chemistry of pyrogenic carbon, the main distinguishing feature of Terra preta. The symposium will function as a warm up and introduction to the subject in preparation for three candidates of the Terra Preta Program who will defend their theses in the Aula of Wageningen on the 1st July 2015.

       Successful Thesis Defence

 Congratulations to Dr. Sagrilo!

Edvaldo successfully defended his PhD Thesis with the title "Soil and plant responses to pyrogenic organic matter: carbon stability and symbiotic patterns" at the Aula in Wageningen on the 9th December. Edvaldo is the first of the cardumen to defend his thesis. He has now returned to Brazil where he continues to work for Embrapa and we wish him well for his future career!





Welcome to the Terra Preta Program!!

Several international conferences in 2015
Several international conferences related to soils, terra preta, and/or biochar will take place this year.  Click on the name of the conferences to visit their sites and get more information.
- Climate Smart Agriculture 2015 Global Science Conference 16-18th March 2015 in Le Corum, Montpellier (France)
-5th International Symposium on Soil Organic Matter (SOM). 20-24th September 2015, Georg-August-University Göttingen, Germany

The Terra Preta Program started in January 2010. It is a 5-year long international and interdisciplinary program focussing on anthropogenic soils (also known as "terra preta") that are found in the Amazon basin. The basic idea of the program is very well summarized in the program's full name: 

"Terra Preta do Indio ─ Recovering the Past, Regaining the Future of Amazonian Dark Earths"

In this webpage you will find information about our program, the research topics on which we are focussing, as well as general information on terra preta

This program is being funded by the Interdisciplinary Research and Education Fund (INREF) of Wageningen University.
