Emisiones de CO2 y contenidos de carbono de la biomasa microbiana del suelo en el bosque protector Murocomba.

The present investigation was carried out with the objective of determining the CO2 emissions and carbon contents of the microbial biomass of the soil in the "Murocomba Protective Forest" (MPB). Five treatments (scenarios) of land use were established in remote areas of the BPM and its surroundings. For this purpose, 3 soil samples were collected for each treatment. The total Corganic soil present in each treatment was 19.97 mg / kg for primary forest, 15.40 mg / kg for Forest in regeneration and 15.70 mg / kg for the plantation of G. arborea, which were statistically superior to secondary forest treatments with 13.96 mg / kg and Pasture with 12.50 mg / kg. For the contents of active microbial biomass (AMB) the most significant values were detected in the treatments: Primary forest (control) and secondary forest with 6.65 mg C-mic g-1 of dry soil (mg C-mic g-1 s) , and 5.75 mg C-mic g-1 s, respectively, being statistically similar but superior to the contents found in the treatments: Forest in regeneration, and Plantation of G. arborea, with 5.40 mg C-mic g-1 s, and 5.10 mg C-mic g-1 s and the lowest AMB contents were detected in the pasture, with only 2.10 mg C-mic g-1 s. The soils from the primary forest released 50.38 mg CO2 in 100 g-1 of dry soil hour-1, whose emissions are statistically higher than that of the other treatments. Statistical similarities were found among the treatments: secondary forest, forest in regeneration and plantation of G. arborea with values of 43.56, 40.91 and 38.64 mg CO2 in 100 g-1 of dry soil hour-1, respectively. The soils from the Pastureland released 15.91 mg CO2 in 100 g-1 of dry soil hour-1, whose emissions are statistically lower than those of the other treatments.
