“…The pine plantations may produce as much plant biomass as the native forests (Zaninovich & Gatti, 2020); however, it is formed by very homogeneous canopies and root systems. On the contrary, native forests are composed of a high diversity of deciduous tree species, with abundant and varied root systems (Bergamini & Thomas, 2011; Trentini et al, 2017).…”

“…In southern Brazil, extensive areas of the Atlantic Forest biome have been converted into loblolly pine (Pinus taeda) plantations, mainly for the production of pulp and paper (IBÁ, 2020;Kondo et al, 2021). Compared with native forests, pine plantations obviously have lower plant diversity (Trentini et al, 2017;Zaninovich & Gatti, 2020); however, they also accumulate litter that is more recalcitrant to microbial decomposition (Bini et al, 2013;Olsson et al, 2019;Xu et al, 2020). Therefore, although plant biomass and CO 2 assimilation through photosynthesis are similar to those of native forest (Zaninovich & Gatti, 2020), planted forests can introduce important changes in soil functioning and GHGs fluxes, probably because they alter factors crucial for the ecological functioning of the soil (Veloso et al, 2018(Veloso et al, , 2019.…”

Forest soils can be sources or sinks of greenhouse gases (GHGs) depending on soil attributes that affect biomass and activity of soil micro-organisms involved in GHGs fluxes. In this work, we tested the hypothesis that soil physical, chemical and microbiological attributes, under different forests ecosystems, affect the soil GHGs [nitrous oxide (N 2 O), carbon dioxide (CO 2 ) and methane (CH 4 )] fluxes.The study was carried out in two locations in southern Brazil in 2019, with three experimental plots of 900 m 2 in native forests of the Atlantic Forest biome and in loblolly pine (Pinus taeda) plantations. Air samples released from the soil surface were analysed for concentration and flux of CO 2 , N 2 O and CH 4 . Soil samples were analysed for chemical attributes, density (Ds), soil microporosity (MiPs), soil macroporosity (MaPs), total porosity (TP), water-filled pore space (WFPS), microbial biomass carbon (MB-C), basal respiration (BR), microbial (qMic) and metabolic (qCO 2 ) quotient and activities of soil urease and βglucosidase enzymes. The seasons influenced the CO 2 and N 2 O emissions, probably because of the changes in seasonal conditions. However, native forests consumed more CH 4 than pine plantations. Meanwhile, the native forests presented soils with lower Ds (average 21.5% lower), more TP (average 12.5% higher) and more moisture (average 33% higher), which improved the microbiological attributes of the soil (20% to 60% more MB-C, 67% higher urease activity and 30% higher βglucosidase activity) compared with pine plantations. Native forests contributed more intensely to CH 4 consumption than pine plantations because they present better physical, chemical and microbiological soil conditions. Therefore, it is possible that forestry practices that improve soil physical attributes are likely to contribute to increase CH 4 consumption, and to reduce GHGs emissions in forest ecosystems.

“…Además, durante las últimas décadas, los ecosistemas forestales han estado expuestos a cambios en el régimen de precipitaciones y al incremento de las temperaturas, cuya influencia sobre los bosques nativos del país aún es poco conocida (Masiokas et al 2008;Garreaud et al 2013;Magrin et al 2014;Ferrero and Villalba 2019). Los cambios en el uso del suelo y el clima con frecuencia alteran la fisonomía, la composición y la estructura de los bosques, así como su capacidad para funcionar como reservorios de carbono y biodiversidad (Lewis et al 2004;Chazdon 2014;Zaninovich et al 2017;Zaninovich and Gatti 2020). Una herramienta clave para estudiar estos cambios son los sistemas de monitoreo a largo plazo como las parcelas permanentes forestales (Feeley et al 2011;Aleixo et al 2019;Sullivan et al 2020).…”

Las parcelas forestales permanentes son áreas de muestreo donde se registran periódicamente la identidad, abundancia y tamaño de los árboles, para estudiar cómo cambian los bosques en relación con el clima, los disturbios naturales y los usos y manejos. Hasta hoy, los patrones de cambio observados con parcelas permanentes en la Argentina tuvieron alcance local o regional. Para potenciar los vínculos entre los diferentes grupos de trabajo que promuevan colaboraciones a escalas intra-e inter-regionales creamos la

“…Deforestation for cropland, which is the primary type of land-use change [17], may cause a significant variation in soil ecological processes and ecosystem functions. These effects include variations in the input, output, composition, and dynamics of SOC and disturbances in the balance of the SOC stock [18,19]. Changes in land use from natural vegetation to cropland may cause significant reductions in SOC stocks in the long term.…”

Deforestation for agricultural development or extension is a common land-use problem that may cause a series of changes in the ecological environment and soil carbon stock in planting systems. However, the response of soil physical, chemical properties and carbon stocks in agricultural systems in the initial period after deforestation have not been thoroughly examined, especially in the subsoil. We investigated the variations in the soil physicochemical properties and organic carbon stocks to a depth of 100 cm in a poplar (Populus deltoides cv. 35) plantation, a summer maize (Zea mays L.) followed by winter wheat (Triticum aestivum L.) field after 1 year of deforestation of a poplar plantation, and a wheat–maize rotation field used for decades. The soil bulk density and pH decreased, and the soil total nitrogen (TN), total phosphorus, and total potassium contents increased considerably. The soil organic carbon (SOC) content and stocks (to 100 cm) increased by 32.8% and 20.1%, respectively. The soil TN content was significantly (p < 0.001) positively correlated with the SOC content, and the C:N ratio increased for the field following deforestation. Furthermore, the nitrogen in the poplar plantation and the field following deforestation was limited. We recommend increasing the amount of nitrogen fertilizer following deforestation to improve fertility and this will be beneficial to SOC storage.
