3.4 Response of litter respiration to soil microclimate Soil respiration under the three treatments increased exponentially with soil temperature ( Table 2 ), with almost significant influence of soil moisture, as shown by a quadratic equation; the exception was soil respiration with the double litter treatment at relatively lower temperatures (i.e., when soil temperature was less than 17°C) ( Table 4 ).
