摘要：

In an incubation study the effect of moisture content on CO 2-C production from manure at 25°C was determined. Different non-linear regression models were applied to describe cumulative CO 2-C evolution and a simple first-order model gave the best curve fit. Derived data from the curve fitting procedure were plotted against moisture content. A linear relationship between moisture content and microbial activity up to 50% of the water-holding capacity was followed by a curvilinear response between 50% of WHC and saturation. Equations describing the effect of moisture on dry matter decomposition are given. © 1990 Kluwer Academic Publishers.
