Biochar is basically charcoal used as a soil amendment. It is
promoted as a means of improving soil and as an approach for
sequestering carbon to help mitigate climate change.
During the October 2011 ECHO Asia Agriculture and
Community Development Conference, Dr. Karl Frogner introduced the
concept of biochar and demonstrated how char can be produced from bamboo
(see Dec 7, 2011 blog http://sustainabilityquest.blogspot.com/2011/12/echo-asia-biochar-trial.html). Prior to that, in an ECHO Asia Notes article, Biochar: An Organic House for Microbes, Bryan Hugill described the role of biochar for both agriculture and carbon sequestration.
In May, Dr. Abram Bicksler, a faculty member of the Chiang Mai-based ISDSI (http://www.isdsi.org/)
and research advisor for ECHO Asia, began setting up a planned biochar
trial to be implemented at the ECHO Asia Seed Bank. Finely ground
bamboo char was mixed with ground up, composted cow manure and set
aside for a three-month long period. During this time the bamboo char
is expected to absorb nutrients and microbes from the manure. Around
September, the biochar/manure mixture will be established in select
plant beds so as to monitor and compare the crop performance and soil
properties of beds receiving biochar and those receiving only char or
cow manure.
As with other ECHO Asia trials, we will be sharing results from this biochar study.
