Explain factors affecting rate of decomposition?

Following are the important factors affecting the rate of decomposition: Litter Quality The rate of decomposition depends on the structural and chemical properties of litter. Temperature Temperature regulates the growth and activity of microorganisms. The temperature is different at different elevations. Aeration The oxygen present in the pores of the soil helps in the growth of microorganisms. Here only anaerobic microorganisms can grow and initiate decomposition. Soil pH The presence of cations and anions governs the pH of the soil, which in turn affects microbial growth. Inorganic Chemicals After decomposition, the elements like potassium, sodium, calcium, magnesium are released into the soil. Some of these are used by the microorganisms for their growth. Thus, it affects the rate of decomposition. Moisture The water present in the soil is responsible for various physiological processes of microorganisms present in the soil. .......Hope it helps.......
