Effective Use of Biochar Usually Doubles Crop Yields
6 years ago

Extensive research, in 5 nations, has confirmed that by adding biochar to soils it acts to dramatically increase natural soil microbial activity ... thereby improving natural soil fertility and more than doubling crop yields. Rather than slash-and-burn, some tribes in the Amazon somehow decided to slash-and-char to make the cut timber into a biochar (using slow pyrolysis). As a result it was these tribes who first discovered and documented the miracle of biochar. Our charity, NPI, has perfected a biochar kiln that produces biofuels & green electricity in the process of making biochar from mostly incest-killed timber (we kill the harmful insects in the process). We grind the biochar, and then soak it for 24 hours in a mix of water, manure effluent, and compost/ earth "tea." The biochar is then mixed w/ garden or crop soils ... and we seek to add 8 to 10 biochar to the soil. Typically, the result is a long-term 200 to 300 percent increase in crop yields. By increasing crop production in this amount, healthful foods can be provided to those who are nutrient deficient. To help promote use of biochar by smallholder farmers, worldwide, NPI has designed a clean cook stove that produces biochar and green electricity during the process of cooking. Syngas produced during the pyrolysis of woody materials is burned to provide about 80 percent of the heat needed for cooking. Clean stoves avoid health problems that result from cooking indoors on open fires. Biochar produced is easily added to garden soils. The green electricity, produced by thermoelectric means, will provide lighting for many Third World dwellings that usually have no electricity. Biochar is a win, win, win innovation.
