Terra preta on TV
a very interesting film about Terra preta was there a few weeks ago SWR:
FILM VIEW
Here are some excerpts:
beetroot - the size of a handball, zucchini slices - as big as pie plates, leeks - as thick as a vacuum cleaner tube. The mystery of the giant vegetables originated 10,000 kilometers west, in the rain forests of the Amazon: It's a forgotten secret of the Indians, the scientists have rediscovered - an ecological treasure: the terra preta, 'black soil "in Portuguese. A soil-miracle, made centuries ago by people from charcoal, manure and kitchen waste. Up to several meters thick, covers the black soil in many places the Rain forest floor. It multiplies itself, stores water and nutrients to an extent, the scientists fascinated. Terra preta on
are plants such as the traditional cassava three times as great as on agricultural land. One reason for this is contained charcoal, which collects a large extent nutrients and water. But it is not the whole secret, probably the most fertile farmland in the world: For years scientists have been trying feverishly to why the terra preta can store the nutrients for so long and why they themselves propagated. What was the Indians almost in his lap, long before the science presented an insoluble problem. Now the secret was in the northern Palatinate Hengstbacherhof revealed. There, Joachim Boettcher and his colleagues at areal chance for tests on the right mix of necessary soil organisms - bacteria and fungi - encountered. Now they can make the first an almost true to the original terra preta.
The raw material for the terra preta in the Palatinate, is biologically pure charcoal. There are also green cut waste and digestate from the biogas plant. Herein lies much of the nutrients in it, the terra preta also make them so valuable. The mass is enriched with bacteria and fungi, and then stored. After two weeks, the Terra preta ready for use in Versuchsgarten.Seit four years, the building on the Palatine black soil on vegetables, with astonishing results: Giant vegetables that tastes great at the same time. The yield per plant by up to four times higher than in conventional soil. But that's not all: Terra preta could also help to save our climate. Scientists are convinced that the miracle of the Amazon soil can absorb harmful carbon dioxide to a large extent and permanently bind the soil. The Terra Preta
pioneers from the Palatinate dare now the next step. Together with the company and the University of Juwi Birkenfeld planning the world's first production facility in terra preta Hunsrück. From 2011, the Energy Park in Morbach 50,000 cubic meters per Terra preta Year are produced. First, particularly as a plant substrate for hobby gardeners. So the people of the Amazon would probably never expected. What their ancestors many centuries, of course, could just, well revolutionize agriculture around the world.
