Does Crop-Livestock-Forest Systems Contribute to Soil Quality in Brazilian Savannas?

Abstract: In this paper we discuss the impact on conversion degraded pasture areas into an integrated crop, livestock and forest system (ICLFS). We collected 30 soil samples at 0-0.1 m depth in five agroforestry systems, degraded pasture and native areas along Brazilian Cerrado biome. We analyzed the influence of chemical variables on microbial biomass carbon and enzyme activity using multivariate statistic analysis. The land use explained only the variation of microbial biomass carbon and seasonality explained the vari… Show more

“…Soil quality in integrated crop–livestock–forestry systems is assessed by a range of soil quality indicators, including biological, physical and chemical soil properties or processes (Borges et al., 2019; Laroca et al., 2018; Zago et al., 2019). Overall, such systems are known to promote a better soil environment (Kichel et al., 2014), which is related to the synergistic effects among the components in integrated crop–livestock–forest systems (Costa et al., 2018).…”

“…Systems managed with pastures are important in maintaining soil quality, given the extension of these cultivated areas across the planet (Salton et al, 2008;Santos et al, 2019), especially pastures with adequate management, which present an increase in SOM in surface and subsurface layers due to root decomposition (Coonan et al, 2019;Malcolm et al, 2019). On the other hand, pastures undergoing degradation stages, with low biomass production and soil cover and under the beginning of the emergence of erosive processes, negatively influence soil quality, compromising soil C quality and quantity (Segnini et al, 2019;Zago et al, 2019;Webster et al, 2019).…”

“…Usually, fast-growing eucalypt plantations are grown in monoculture. There is, however, a recent increase in crop-livestockforest system area [6]. Eucalyptus trees established in crop-live-stock-forest systems are usually planted in rows, presenting lower stand density and diverse canopy structures.…”
