“…Such yields were comparatively higher than the local average (~1.5 t ha −1 ) as reported by Vilas Boas et al (2018). These results reinforce the overall relevance of a holistic evaluation of soil attributes to assess soil quality and its relationship with plant growth (Askari & Holden, 2014;Obade & Lal, 2016). This is particularly relevant for the reestablishment of plant cover in areas impacted by mining activities.…”

Mining activities cause severe impacts to soil, the restoration of which requires specific management, and proper evaluation and monitoring. In this research, our objectives were to study recovery strategies and integrate indicators for monitoring the reclamation of an agricultural soil after bauxite mining. Distinct fertilizations (nonfertilized control [CT], poultry litter [PL], chemical fertilization [CF], and PL + CF combined) and intercrops (bare soil with no intercrops [NI], grass [G], legume [L], and G + L combined) treatments were used as recovery strategies to restore soil capacity to sustain a coffee plantation. We selected 27 quality indicators to compare the premining condition, postmining (reconfigured topsoil), and 19 months after the application of fertilization/intercrops treatments. We used univariate statistics to select soil quality indicators and multivariate analyses to group the selected indicators into organic, chemical, physical, and microbiological properties. From each group, one representative attribute was selected, and its averaged weight was summarized into a soil quality index (SQI). In postmining, the estimated SQI was approximately 65% lower than in premining. The SQI recalculated 19 months after the application of fertilization (PL or PL + CF) and intercrops (G, L, or G + L) was 23% higher than in postmining and showed strong correlation with coffee bean yield (at 27 months). Coffee bean yield was highest in plots with L or G + L receiving PL or PL + CF. We conclude that organic amendments and intercrops are suitable approaches to recover soil following bauxite mining, and soil indicators can be integrated to properly monitor the land reclamation progress.

“…Land capability evaluation aims to identify criteria for environmental limitations in the efforts of sustainable land use planning [23]; [24]; [25]; [26]. The classification of land capability is a scientific activity to assess the physical characteristics of land, soil quality, land management and farming activities [27]; [28]; [29]; [30]; [31]; [32].…”

Evaluation of the environmental carrying capacity should be measured as part of sustainable land use planning. One of methods to evaluate this carrying capacity is land capability evaluation.. This study aims to evaluate the suitability of landuse in each of land capability classes in Mojokerto Regency. Land capability is obtained by spatial analysis and overlay of several criteria for land capability, included soil texture, effective soil depth, drainage, land slope, and soil erosion. The description of actual landuse is obtained using landsat 8 OLI images at coverage time in May 2018. The results of study show that the land capability in Mojokerto Regency varies from Class I to Class VIII. The actual land use in Mojokerto Regency are about 98% or 95314.33 Ha are suitable to the land capability, and 2% or of 2078.67 Ha are unsuitable to the land capability. Based on the environmental carrying capacity, about 78.85% or 76798.89 Ha of land in Mojokerto Regency are allocated accordingly, and 0.90% or of 875.29 Ha of land are allocated beyond their carrying capacity, 19.39% or 18884.18 Ha of land are allocated in a conditional manner so it needs any specific treatments of landuse.

“…It is a complex functional concept that cannot be measured directly in the field or laboratory, but it can be inferred by soil properties and processes sensitive to land use and management, denominated soil quality indicators (Cardoso et al, 2013;Zornoza et al, 2015). Although many SQ assessment strategies have been tested (Andrews et al, 2002(Andrews et al, , 2004Mukherjee and Lal, 2014;De Paul Obade and Lal, 2016), there is no comprehensive, universally agreed-upon strategy for evaluating either natural or anthropogenic ecosystems. Currently, however, one of the most promising approaches is the Soil Management Assessment Framework (SMAF) described by Andrews et al (2004).…”
