Carbon-Circulating Agriculture

  Carbon-Circulating Agriculture (carbon cycle by agriculture) is one of the ways for natural farming through carbon cycle to achieve same level of carbon fixation to forests with keeping same (or more) productivity with ordinary agriculture method. It is distinguished from ordinary agriculture by effective utilization of microorganism (fungus and bacteria) in the soil.
carbon cycle figure
  In ordinary agriculture, chemical fertilizer is used as manure, and after the harvest, the residua (stems or leaves) will be dumped out, mostly burned out. It means, even some carbon fixation occurred, most of them would be emit back as CO2.
On the other hand, in Carbon-Circulating Agriculture, such residua will be decomposed by microorganism and become natural manure, as in forests. So, the carbon fixation is maximized, will reach the natural levels of forest.
We all know trees in the forest can be grown up even nobody gives them fertilizer. Leaves from trees fall down to the land, then microorganism decompose it and make the soil fertile. So, trees will grow up well on the fertile soil, and leaves will fall downcsuch natural circulating activity is the key factor of the forest.
In Carbon-Circulating Agriculture, we set up this carbon cycle activity of the forest on the agriculture field. For speedy circulation, residua and other natural carbon resources is put into a form which microorganism can decompose easily, so we can attain more productivity than ordinary agriculture method. And, as there is no usage of agrochemical and chemical fertilizer, we will harvest high quality vegetables, and be categorized as organic vegetables*.

  *In most country, crops that can display as "Organic" are certified by approved certification organizations only.

The Effect
  According to the IPCC's Fourth Assessment Report (AR4), global greenhouse gases emissions due to human activities have grown since pre-industrial times, with an increase of 70% between 1970 and 2004. Food and Agriculture Organization of the United Nations (FAO) indicated on its Global Forest Resource Assessment 2000 (GFRA 2000), global forest area in 2000 was 13,064 million hectare, decreased 9.4% from 1990. To avoid global warming, it is important to secure photosynthesis and carbon fixation. But two statistics above show the trend is running counter to this issue.
  To solve this problem, Carbon-Circulating Agriculture is one of the critical answers. By maintaining productivity and securing photosynthesis and carbon fixation, the vegetable field will be an equivalent to forest in the view of carbon fixation.
  As of 2001, we have 13,067 million hectares of farm land in all over the world, almost same size of the global forest area. Can you imagine what will happen, if we could make all this farm land adopt the Carbon-Circulating Agriculture?
