Abstract

[automatically translated] The present work was conducted on soil sampled within a olive grove with the objective of evaluating the respiration rate due to heterotrophic component (microbial) as a function of temperature and humidity factors. The respiration rate was monitored on the ground incubated at five levels of temperature, 10-15-20-25-30 ° C and four levels of volumetric soil water content (θ) 12,6-18,9-25,2 -31.5% (v / v). The breathing values have presented a range of variable values between 78.20 and 14.81 micrograms CO2 g-1 soil d-1, respectively, at 30 ° C and 10 ° C and 12.6 and 31.5%. The Q10 values, or the response of respiration in relation to temperature increments of 10 ° C are instead varied between 1,71 and 1,50. The joint action of the two factors,
