In the first part of our series, we have Terra preta presented as a way to enrich the soil to improve plant growth with carbon. As studies have shown is that this Carbon for thousands of years in the soil. Because Terra preta but is made exclusively from plant material, offers the possiblity of the atmosphere of carbon dioxide (CO2) to escape permanently. Because the plants absorb CO2 during their growth phase from the air and convert it to plant your own carbon compounds. When preparing now from the plants Terra preta, the carbon is permanently fixed in the ground.
For some time discussing what options there are for climate protection CO2 in the atmosphere to be reduced. This CO2 is well known in the combustion of fossil fuels such as coal, oil and gas. It is therefore the carbon Soil removed and placed in the form of carbon dioxide in the atmosphere where it affects climate by causing a gas to global warming substantially. Since much of this carbon dioxide in coal-fired power stations does one has thought about whether it is possible, just to separate the carbon dioxide at the power station chimney. You should then be stored in liquid form in the former gas reservoirs or salt caverns. This method has several serious drawbacks: first
The process is very energy-consuming and increases the use of coal for the same amount of electricity by 30-40 percent.
second Every year in Germany alone would have stored several hundred million tonnes of CO2 in liquid form be.
third Because of storage power plant and usually are not identical, large amounts of liquid carbon dioxide to be transported over long distances. The result is a threat to the population because a higher concentration of CO2 is a respiratory poison.
4th In any case, one could detect with this method, only a small part of total emissions, for example because it is not possible to neutralize the CO2 emissions by millions of cars and home heating.
5th It is also still entirely unclear whether it can succeed at all this CO2 to be stored for long periods of time underground.
Figure 1 storage of CO2 underground
Terra preta contrast, seems to be suitable to get this problem under control permanently. Nevertheless, you should have no illusions that this method could solve all our problems in the energy sector, because the soil is limited receptive to carbon.
To this the example of the old circle to illustrate Witt Location:
every citizen in Germany is responsible for about 10 tonnes of CO2 emissions a year, equivalent to almost 3 tons of pure carbon (because 27% of the mass of carbon dioxide, carbon)
would So alone Former district in Wittlage about 120,000 tons of carbon per Year, or about 500 tons per day, are applied to the fields to compensate for the emissions.

why should we, despite this possibility in our efforts to renewable energy sources continues. On the other hand, it is of course only because of the positive effects of terra preta useful on soil fertility, to take that route.
It is therefore the object of an appropriate infrastructure for the production and distribution of the terra preta in the build Altkreis Wittlage. Therefore we will in the coming weeks to designated contact include professionals and interested people who can approach us with this task. We will inform the reader of the ELK informed of our progress and continue to communicate facts about the benefits of the terra preta in this way.
In the next issue, we go closer to the technology of charcoal production.
