متن کاملIs resistant soil organic matter more sensitive to temperature than the labile organic matter?
A recent paper by Knorr et al. (2005a) suggested that the decomposition of resistant soil organic matter is more temperature sensitive than labile organic matter. In Knorr et al.’s (2005a) model, the reference decay rate was presumed to be same for all pools of soil carbon. We refit Knorr et al.’s (2005a) model but allow both the activation energy and the reference decay rate to vary among soil...

متن کاملGravimetric Determination of Soil Organic Matter
Studies were carried out to evaluate a gravimetric method for the determination of soil organic matter by the mass loss at 300C. The gravimetric method was compared with Walkley-Black, using several brazilian soils with variable chemical and physical properties. Gravimetric method was positively correlated with Walkley-Black method with the following linear regression equation: y = 3.72x + 0.29...
