ACOSTA MIRELES, Miguel et al. Carbon in soil, herbs and shrubs in a plantation forest in Jalisco, Mexico. Rev. Mex. Cienc. Agríc [online]. 2020, vol.11, n.6, pp.1377-1387.  Epub Oct 11, 2021. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v11i6.2427.

Adequate sustainable forest management, whether in a plantation or a natural forest, creates carbon sinks that are usually constant over time, however, it is unknown how it affects the activities of vegetation management in carbon sinks in the forest ecosystems. The objective was to estimate the carbon concentration in herbaceous and shrubs, leaf litter and two soil depths (0 to 15 cm and 15 to 30 cm), in a forest plantation with the presence of four tropical species under two management conditions. Carbon measurements were made in grasses and shrubs, leaf litter and two soil depths under two managed and unmanaged conditions in 30 plots with the presence of purple rose (Tabebuia rosea), teak (Tectona grandis), melina (Gmelina arborea) and parota (Enterolobium cyclocarpum). After the collection, the dry weight of each sample was weighed and determined, to determine the carbon content of each of the components. An Anova and Duncan’s test were then performed to determine if there are significant differences. The plot with parota and with management was the one that registered the highest amount of total carbon with 73.94 Mg ha-1, while the plot with teak with management reported the lowest total carbon content, with 45.63 Mg ha-1. As for the carbon content in the soil, it decreases by approximately 35%, as its depth increases, with significant differences.
