Correlation analysis of the amount of carbon in the soil with some soil properties using regression equation (Regression Analysis) to cut the backward variable that is not a linear relationship. The dependent variable is Amount of carbon in the soil (Soil Total Carbon) and the independent variable is the amount of organic matter (Soil Organic Matter), the amount of phosphorus to plants (Available Phosphorus), soil pH (pH), bulk density of soil (Bulk Density. ) and the moisture content of the soil (Soil Moistures), the quantity of carbon in the soil. Correlated with the amount of organic matter in the soil and reactions. Table 4-10 details
