Richer Soil From Old Bones - Futuris

 

Scientists from a European research project called Refertil are trying to develop an organic phosphorous fertilizer out of an unlikely ingredient; pig bones.

The bones are burnt at an average temperature of 600ºC, in an oxygen-free vacuum. No gases are emitted into the atmosphere. The resulting product, known as bone biochar, is rich in minerals and, unlike agro-chemical fertilizers, it is virtually free of heavy metals. Seemingly, an ideal organic phosphorous fertilizer, according to the researchers.
