The Benefits Of Conservation Agriculture

Apparently, conservation agriculture is able to reduce the emission of greenhouse gases as well as global food security. First of all, according to the definition of greenhouse gases (GHG) “The atmospheric concentrations of some greenhouse gases are being affected directly by human activities namely carbon dioxide, methane, nitrous oxide, ozone, chlorofluorocarbons and hydrofluorocarbons.
Water vapour is also a major greenhouse gas, but its concentration in the atmosphere is not influenced directly by human activities.” (Climate Change in Australia, 2015). The future human civilisation will be threatened by rising atmospheric concentration of carbon dioxide, nitrous oxide and methane. Roughly, agriculture activities were worth 15% of the global

Nowadays, there are 1.8 tons carbon dioxide per hectare had been stored up into clay, the total amount of tons of CO2 in soils were represented almost 35% of global emission of fossil fuels in 2007 (Conservation Agriculture Carbon Offset Consultation, 2008).By using CA practices worldwide, carbon sequestration has occurred during the chemical reaction of photosynthesis. A numerous crops and plants mean a large amount of carbon dioxide will be absorbed intensively due to carbon inputs. Nevertheless, if soil erosion happens, the more CO2 will be released from the decomposed soils apart from less amount of CO2 absorbed by farming and environment. Better-quality of soil texture is correlated with the higher density of carbon contents, the correlation is leading to greater harvest under conservation farming. The documentation between soil organic carbon and earth content is well recognised with a strong positive relationship (Gatere, et al., 2013).
Accordingly, avoiding from soil erosion is related to recharge of soil feature as a result of better infiltration, reduction in greenhouse gases resulting from carbon sequestration, water-holding capacity and also increase infiltration which is related to conservation
