Energy balance in the production systems of the castillo variety coffee, in the department of Nariño (Colombia)
This research was aimed at estimating the energy balance based on carbon fixation in four coffee production systems, located in four municipalities of mayo´s, central and western subregions of the department of Nariño (Colombia). The data collection was implemented through the application of allometric measurements for the tree species used in the treatments and destructive purposes for coffee through the extraction and fragmentation of each of its components. The assessments were carried out during the first and the second semesters of 2019 in five-year-old production systems. It was found that the largest deficit was obtained in the municipality of La Unión with the treatment 1. Meanwhile the maximum surplus was obtained in treatment 3 in the municipality of Sandoná. The highest emission values were presented in the municipality of La Florida with the Treatment 2, where the highest emission activity corresponded to a nitrogen fertilization. The interaction between municipality and altitude obtained statistically significant carbon average capture. La Unión´s systems with the higher altitude were of a higher average. And in terms of treatments there is no difference among the coffee and shade alliance. The results indicate that coffee production systems in association with shade forest species contribute to the climate change mitigation. These ecosystems might be crucial in the carbon fixation and as for the payment of environmental services.
