Abstract: The conversion of areas cultivated with sugarcane into eucalyptus forests can promote improvements in the physical, chemical and biological properties of the soil. Within this context, the aim of this study was to evaluate the changes in the stocks and levels of carbon and nitrogen and soil-aggregate stability in an area of transition from sugarcane to eucalyptus in the State of Alagoas, Brazil. The study was carried out on a rural property, located in the district of Atalaia. The systems under evaluation cons… Show more

“…Another fact to be highlighted is related to young trees (1 year), in which organic residues are reduced when compared to older trees (Barreto et al, 2014;Cook et al, 2016). In agricultural areas that have fragile aggregates in soil, especially in the superfi cial layer, there is a probability that they disappear and disperse due to the strong impact of rain (Medeiros et al, 2018).…”

“…In the northeast of Brazil, state of Alagoas, areas cultivated with sugarcane (main economic activity) have been losing ground to eucalypt plantation (Medeiros et al, 2018), and around 14 thousands hectares are cultivated with this crop. This change is due to several factors, including the depreciation of ethanol (17%) and sugar (27%) prices, competing with south-central region (CONAB, 2016), and, mostly, due to forestry growth, which is responsible for an annual value of US$ 7 billion in Brazil (IBÁ, 2017).…”

“…Furthermore, studies show a lower SOC storage in reforestation with Eucalyptus compared to the reference area. Some exceptions, however, were observed mainly on clay soils (Corazza et al 1999;Lemma et al 2006;Pulrolnik et al 2009;Medeiros et al 2018).…”

“…The SOC storage was, in general, lower in forest restoration models compared to natural forests and grasslands, with average values of − 6.5% (N = 46) and − 3.9% (N = 24), respectively. Some comparisons between croplands (N = 3) and monocultures with Eucalyptus showed a positive average net difference of + 2.4% in Eucalyptus than in croplands (Medeiros et al 2018). A few studies showed a positive net difference between monocultures with Hevea (Maggiotto et al 2014;Vicente et al 2016) and Pinus (Cassol et al 2019) versus grasslands.…”
