Abstract

An incubation experiment was conducted to investigate CO2 emission potentials of Ultisol soils under residues of peanut (green manure) and rice (rice straw) and moisture regimes 60% (W1) and 120% (W2) of water holding capacity at different temperature ranges (low to medium 5–20 °C, medium to high 25–30 °C and very high 35–45 °C). The samples of Ultisol soils collected from, Dera Ghazi Khan City of Punjab, were used in this study. The results suggested that applied amendments e.g. addition or incorporation of plant residues are in fact major factors which control the CO2 emission potential of soils by converting soils from CO2–C sources to sinks. On the other hand, other abiotic factors like temperature and moisture are indirect regulator of CO2 production and emission by influencing decomposition of these incorporated organic inputs
