Carbon management

The Soil Fertility Project is an interesting project that attempts to use biochar to address soil fertility and climate change both in Wales in weed eradication projects.

In the Indian project ( http://www.soilfertilityproject.com/Soil_Fertility/Indian_Project.html). The participants started by using the Anila stove to product biochar, but found that it was unworkable. Now they are using a digestor to process wet waste, get some energy, and use the slurry for fertilizer. They are also using a small BiG Char unit to process green waste into biochar.

we at Dr MGr Jatropha Biodiesel Project are now engajed in Jatropha oil manufacture
and also we plant bamboosa Vulgaris Bamboo
we have plans to convert all the Bamboo to Charcoal and supply to the world

The Austrialian Department of Agriculture of Fisheries and Forestry has issued a thoughtful summary paper that surveys the existing research on with biochar, and its implications for agriculture and suggests further areas of research.

Biochar: implications for agricultural productivity

Country: 

A study recently completed in New Zealand found that adding biochar to the soils of pastures where Cows (ruminants) were grazing sharply decreased the excess nitrous oxide from the cows urine. It appears that the biochar helps the soil absorb the extra gasses although long term testing of the effect of cow urine and pasture with biochar still needs to be done.

Since December 2008, more than 1500 subsistence farmers in Cameroon's South-West Region (SWR) have been participating in the largest-ever field trial testing the effects of biochar on crop productivity. The first results of this ongoing experiment, based on maize planted in a large series of plots, are now available. The data can be described as 'remarkable', in that they demonstrate how biochar consistently helps to boost crop productivity in tropical soils, sometimes in a spectacular manner.

The preliminary results suggest that biochar may offer a solution to hunger and food insecurity amongst the world's poorest, as well as to soil depletion and tropical deforestation.

Comment to bioenergy with carbon storage (BECS)

Carbon-negative bioenergy to cut global warming could drive deforestation:
An interview on BECS with Biopact’s Laurens Rademakers Mongabay.com (November 6, 2007) http://news.mongabay.com/2007/1106-carbon-negative_becs.html


The article on mongabay.com deals about a proposed mechanism for generating carbon-negative bioenergy. Bioenergy with carbon storage (BECS) holds out the prospect of reducing CO2 from the atmosphere while producing carbon-negative energy. The article provides an informative introduction on how “carbon-negativity” is feasible and assumes geosequestration (developed from the “clean coal” industry,
CO2 capture in depleted oil and gas fields, saline aquifers etc.) as the sequestering tool. Laurens Rademakers delineates the risks such as deforestation of tropical rainforests and leakage of geosequestration. In addition these technologies require vast capital inputs and large scale projects.
