Soil CO2 emissions from Northern Andean páramo ecosystems: effects of fallow agriculture.

Principales Conclusiones

Soil CO2 emissions from páramo mainly depend on SOM biological accessibility. Accessibility was determined by two key factors: (i) the topographic aspect that strongly controls theSOM content along with the weights of labile and recalcitrant C pools and (ii) soil aluminum that acts as a chemical SOM stabilizing agent.Cultivation-fallow cycle merely produces moderate changes in SOM quality and, consequently, the CO2 emission capacity of these soils remains only temporary altered, mainly due to both the SOM stability and the low-impact characteristics of agricultural systems with long fallow periods that permit soil recovery.
