“…Historically, eucalypt plantations provide charcoal, fi rewood, wood, cellulose and biomass for energy generation (Korchagin et al, 2019). Furthermore, these forests contribute to the environmental conservation, since they improve soil quality, release lower levels of greenhouse gases (GHG) and are natural carbon sinks (Zhang et al, 2019;Souza et al, 2020).…”

“…Eucalypt trees deposit organic residue on soil, which contributes to an increase in soil organic matter (SOM) and, consequently, in soil organic carbon (SOC) content over time (Vicente et al, 2019). However, SOC content in eucalypt areas depend on a several factors such as type, layer and mineralogy of soil, climate conditions, growing time, management practices, among others (Hernández et al, 2016;Korchagin et al, 2019;Zhang et al, 2019;Cavalli et al, 2020).…”

“…In general, eucalypt reforestation improves physical, chemical and biological properties of soil (Guedes et al, 2016;Medeiros et al, 2018;Korchagin et al, 2019;Vicente et al, 2019;Cavalli et al, 2020;Souza et al, 2020), but literature review is limited when it comes to the eff ects found in the transition from sugarcane cultivation to eucalypt plantations. Moreover, in general, the assessment of soil quality requires the use of a large number of variables, which in most cases makes research unfeasible due to fi nancial, logistical or operational reasons (Hair et al, 2009).…”

Reforestation is considered an effective method to improve soil quality and drain atmospheric CO2 by sequestering carbon, in both soil and vegetation. In this regard, the aim of this study was to evaluate the effects of converting areas cultivated with sugarcane to eucalypt plantations (Eucalyptus spp.) on soil quality and carbon sequestration in a Latossolo (Ferralsol) in the Atlantic Forest region of the Alagoas state, Brazil, through multivariate analysis. The systems under evaluation consisted of four areas: one area cultivated with sugarcane for approximately 20 years, taken as the reference area of this study, and the other three adjacent areas cultivated with eucalypt at 1 (E1), 3 (E3) and 6 (E6) years of age, previously cultivated with sugarcane. Physical (bulk density - BD, Mean weight-diameter - MWD, geometric mean diameter - GMD and aggregate stability index - ASI), chemical (soil organic carbon - SOC, total nitrogen - TN, labile carbon - LC and recalcitrant carbon - RC) and biological (Microbial biomass carbon - MBC, soil carbon respiration - C-CO2 and metabolic quotient - qCO2) properties of soil were evaluated. Data were collected, standardized and submitted to exploratory analysis with principal components. The results show that SOC, LC, TN, GMD, MWD and ASI increased, while BD showed a reduction in E3 and E6 systems. The conversion of sugarcane cultivation with burning of straw and manual harvest into eucalypt plantations was efficient at promoting SOC sequestration and improving physical, chemical and biological properties of soil.

“…Outra possível explicação para o menor (p ≤ 0,05) conteúdo de argila no SRZ e no SEP do que no SSC (Tabela 2), o qual deve sofrer uma influência da raíz, poderia ser a possibilidade de ocorrer dissolução de argila pela acidificação da rizosfera (Korchagin et al, 2019). Todavia, no presente estudo não foi observado redução do pH na rizosfera e os dados evidenciam claramente que a redução de argila foi associada ao incremento de areia e silte nestes ambiente (Tabela 2), isto é, pseudo-areia e pseudo-silte como discutido anteriormente.…”

“…As raízes podem atuar acelerando o intemperismo dos solos pela exsudação de ácidos orgânicos (que levam a redução do pH), redução do O2 e incremento do CO2 na rizosfera (Richter et al, 2007). Isto pode levar a alterações na mineralogia do solo em alguns casos (Jilling et al, 2018;Korchagin et al, 2019). Todavia, no presente estudo, como já mencionando anteriormente, não ocorreu acidificação da rizosfera, isto é, redução do pH no SRZ (Tabela 2), o que impossibilitou a ocorrência de alterações mineralógicas.…”

Primary minerals of the parent material undergo weathering during the formation of terrestrial soils to varying extent. As a result, secondary minerals develop, which comprise, among many others, hydroxy-interlayered minerals (HIMs). These minerals have formed by interlayering of hydroxy-metal complexes (especially of Al 3+ , also Mg 2+ , Fe 2+/3+ ) into micas, expansible 2:1 phyllosilicates and forming oligomers, or by weathering of primary chlorite. The degree of interlayer filling and the stability of these fillings affect several physico-chemical soil properties, for instance the cation exchange capacity. Although many studies have been conducted on formation, occurrence, and properties of HIMs in soil during the last decades, several challenges still exist. These challenges include analytical identification and quantification of HIMs in soil, the nature of the interlayer filling and the identification of favorable conditions in soil for the formation of HIMs. In order to deepen the understanding of formation, properties, and fate of HIMs in soil, we critically reviewed the available literature. Based on the review, we recommend using a new structural model that enables quantification of hydroxy-interlayered smectite in soil by X-ray diffractometry, laboratory experiments on the formation and preservation of different types of interlayers and considering the temporal and spatial dimension of the formation of HIMs in soil in more detail.
