Use of Minerals Fractions As Indicators for Evaluation of the Potential Activity of Emission Areas of Greenhouse Gases.

Due to anthropogenic factors some soil properties can be modify, particularly nitrous oxide emissions (N₂O), which are associated with fertilizer application under humid conditions. The production, consumption, and transportation of NO₂ is hardly influenced by soil structural changes and water content, associated with different uses of soils. Nitrous oxide, identify as greenhouse gas, can be exchange between the soil and atmosphere this process is an important factor that contributes to the global warming. The objective of the research is to evaluate the mineral fractions of different soils and test those fractions as a potential adsorbents or emitters of greenhouse gases. The results show a pH range between 3.5 to 4.2; organic carbon range 12.65 to 128.46 mg/g, and the nitrogen content range 0.01 a 0.3mg/g, and the texture is loam and silty clay loam. Also, samples of N₂O emissions where collected from different soils such as Gleysols, Cambisols, and Acrisols.  Average flux gases range between 172 to 778 kg N₂O-N ha^-1. All dates were evaluated using analysis of variance (α= 0.05) and simple regression, the results gives positive correlation linking production and N₂O emission gases, N content (p=0.00001), carbon content (p=0.0008), water retention (p=0.0013) and percentage of humidity. The sand fraction show low gas emission. On the other hand, to high percentage of clay content shows high values of gas emission, especially during the dry season. This observation suggests that gas emission depends of humid conditions.
