The replanting process has an effect onthe disposal of biomass, plant health management, and agro-ecological conditions due to the disturbance that is generated.This document addresses soil respiration (CO2flux) as a responsevariable of crop replanting. Seven renovation methods used inColombia were tested. The measurements were taken over timeafter the disturbance and planting of the new crop. This study wascarried out in the municipality of Tumaco between August of 2009and June of 2011 using 7 methods of renovation and 4 stages ofcrop development. The CO2flow was measured at 12 points in eachplot. There were no significant differences for the CO2emissionamong the replanting methods. The average value for respirationwas 929 mg CO2m-2h-1(± 270.3); however, significant differenceswere found over time. This response was not related to fluctuationsof soil temperature and moisture; therefore, there should be anassociated response to biotic factors (microbial organisms) notestablished in this study. The values suggested that the soil of theplots under a replanting process emitted considerable quantities ofcarbon into the atmosphere, but the emissions declined over timeand, in turn, were offset by the photosynthesis of the new crop (14μ CO2m-2s-1± 1.4, data not shown), creating an overall positivecarbon balance. 2015 artículo científico 0304-2847 https://www.redalyc.org/articulo.oa?id=179939267002 en http://www.redalyc.org/revista.oa?id=1799 Revista Facultad Nacional de Agronomía - Medellín application/pdf Universidad Nacional de Colombia Revista Facultad Nacional de Agronomía - Medellín (Colombia) Num.2 Vol.68 |
