Humic acid and carbon cycle

Global soil humic acid (HS) of about 2.4 trillion tons of carbon, accounting for 60% of total organic carbon the biosphere, “is a major source of atmospheric CO2, environmental and atmospheric CO2 concentration is very sensitive to changes in carbon aggregates”

In other words, in Earth’s carbon cycle of soil HS play “valve” effect. If the soil break down more than 10% HS, atmospheric CO2 concentration will increase 30%,

Humic Acids impact on carbon balance. Ecological balance in the normal state, the atmospheric concentration of CO2 will not have much volatility. In fact, nearly 100 years of atmospheric CO2 has increased by 30%, the carbon balance of the Earth system is in jeopardy.

The reason, in addition to industrial emissions, the main ecological damage related to soil. C of the total forest and grassland reserves of 69% organic humic acid, a great impact on the carbon balance. Only in recent years due to deforestation and the release of C reached 10 to 20 million tons / year.

The impact of extensive farming can not be ignored, because farming in the 1990s and the release of C more than 80 years more than doubled. Accelerated decomposition of soil HS by the release of more CO2, the actual to the global warming “fuel.” Therefore, the “carbon sequestration” (protection of soil HS) and “carbon added” (Artificial Shi fulvic acid), is to protect the ecological environment, safeguard the planet’s carbon balance of the major initiatives.
