Biochar In The News

Reducing mineral fertilisers and chemicals use in agriculture is a priority. Alternatives include safe biochar and compost produced from treated organic residues from plant and animal by-products.
USDA Agricultural Research Service research plant physiologist Steve Griffith says biochar made from Kentucky bluegrass showed an increased wheat yield and may have helped conserve moisture and raise soil pH. Using biochar as a soil amendment increased wheat yield from 26 bushels per acre on untreated soil to 67 bushels per acre.
The Washington State Department of Natural Resources has issued a request for proposals (RFP) to demonstrate mobile pyrolysis technologies in the state. According to the RFP, funds for the project are through a grant made available by the USDA Forest Service. Proposals are due by Jan. 31.
Researchers report that wood biochar supercapacitors can produce as much power as today's activated carbon supercapacitors at a fraction of the cost, and with environmentally friendly byproducts.
Researchers at the UPM have developed a carbonaceous material from sewage sludge that when applied to soil can help to improve its quality. The material is called biochar and was prepared and characterized by the research group of Resource Exploitation of the Technical University of Madrid (UPM). The biochar has promising effects because its addition can enhance the quality of soil, and consequently it can enhance crop yields. In addition, it has beneficial properties for the environment.
For farmers in western Kenya, biochar is creating a stir. During scientific trials, farmers applying this special kind of charcoal to their fields found their average maize yield increased dramatically, up to double in some cases. Trials in other developing countries, including Columbia and Brazil, have had similar results. What's more, adding biochar to soil is also thought to mitigate global warming by sequestering carbon into the soil. So is biochar the new green dream? Can it fight climate change and help feed the world, all at the same time? Possibly yes, but not everywhere, a new study shows.
In the first study of its kind, Rice University scientists have used synthetic biology to study how a popular soil amendment called biochar can interfere with the chemical signals that some microbes use to communicate. The class of compounds studied includes those used by some plant pathogens to coordinate their attacks.
ZRS Bistra Ptuj has in November 2013 organized an open seminar titled "Biochar and energy use of biomass". The seminar was dedicated to biomass producers, manufactures and fertilizers users, energy users, educational and research institutions, technical stakeholders and representatives of the relevant ministry.
