Terra preta irish style, it wasn't just going on in the Amazon and maybe some scientist that have an interest in biochar should start looking nearer to home (both here and in Europe) to see how the hills and slopes of mountains in their countries and along the west of Ireland were farmed using the practice of 'Pairing and Burning' the evidence is still there both from a distance as improved lands surrounded by heather land and in the ground as fragments of charcoal. Gerard Madden in his book 'Sliabh Aughty Ramble' also mentions how the heathery land of the Aughty mountains was dug, dried and burned and applied back on the land as a fertilizer.
