“…) to agricultural land (1.22 g cm -3 ), then increased further to 1.43 g cm -3 in degraded mine land soil, with its accompanying decrease in total porosity ( Table 1). The decomposition of litter in the forested area resulted in increased organic matter content which in turn increased porosity (pore spaces) and reduced bulk density, confirming results of other related studies [24,25]. In their studies on degradation and tillage operations, Ahirwal and Maiti [26], Blanco-Canqui et al [27], Blanco-Canqui and Ruis [28], Paltineanu et al [29] also observed high soil bulk density in agricultural and degraded lands which was due to cultivation, management and tillage operations in such areas.…”

Land use conversion significantly impact on sensitive soil quality parameters such as microbial biomass and soil microbial quotient. Therefore, soil microbial biomass and physicochemical properties were compared under three different land use systems namely agricultural land, degraded mine land and an adjacent natural forest in the Newmont Gold Ghana Limited concessional areas, Kenyasi, Ghana. In our field experimentation, an area of 300 m2 was demarcated in each land use type for soil sampling. In each of the land use type, we collected soil 5 samples at a depth of 0-15 cm in both the dry and wet seasons respectively. Parameters we measured included soil bulk density, pH, particle size distribution, organic carbon, total nitrogen, available phosphorus, microbial biomass carbon and nitrogen, and moisture content. Our results revealed that land use type significantly impacted on soil microbial biomass and physicochemical properties. Microbial biomass carbon and nitrogen was higher in the forested land compared to the agricultural land and degraded mine land, which was due to relatively higher amounts of litter inputs. Microbial biomass carbon decreased between 20.23 - 88.36% when land use changed from forested land to other land uses. Significant positive correlation was observed between soil microbial biomass and water content, soil organic carbon, phosphorus, clay, nitrogen. Generally, seasonal variation in our study area did not influence soil physical and chemical properties, however, it significantly affected microbial biomass indices. Findings of our study further revealed the importance of forested area in the maintenance of soil quality parameters.

“…A minimum of five sub-samples were collected, mixed together on site and considered as a composite soil sample. Samplings were carried out at depth of 0-20 cm, since the maximum microbial biomass is devoted to the upper soil horizons [15] and microbial activity is sensitive to changed land uses [16]. The fraction passing a 2 mm sieve was transported refrigerated at 4 • C.…”

The current study was performed to investigate the effects of three different long-term land use intensities on adjacent soil plots, namely a winter wheat field, a grass-covered vineyard, and a cherry farm, on soil biochemical, microbial, and molecular parameters. The results showed the maximum content of soil organic matter (SOM) and microbial biomass carbon (MBC) observed in the grass-covered vineyard. Basal respiration (BSR) and the cumulated respiration (CSR) after 25 days of incubation were significantly higher in the grass-covered vineyard and cherry farm, respectively (BSR 11.84 mg CO2–C kg−1 soil d−1, CSR 226.90 mg CO2–C kg−1 soil). Grass-covered vineyard showed the highest soil biological fertility index (BFI) score (20) and ranked in the class IV (good) of soil biological fertility. Cereal field and cherry farm had lower BFI scores and the corresponding BFI class was III (medium). In addition, the maximum ribosomal RNA copy number and the highest abundance of oligotrophic bacterial groups (25.52% Actinobacteria, 3.45% Firmicutes, and 1.38% Acidobacteria) were observed in the grass-covered vineyard. In conclusion, the grass-covered vineyard is a more conservative system and could have a large potential to improve total carbon storage in soil, mainly because of the cover crop residue management and the low soil perturbation through the no-tillage system.

“…Microbial respiration has a direct relationship with soil organic carbon storage due to the high dependence of soil microbial activity on substrate carbon availability (Zhang et al 2014). Therefore, with higher carbon storage in the later stages of the succession, the basal respiration increases (Soleimani et al 2019). Also, higher amount and stability of organic carbon in forests than in arable lands (Gelaw et al 2015) increase microbial biomass and microbial derivatives and stimulates decomposition products and metabolites (Leff et al 2012).…”

There is a growing body of knowledge that ecosystem functions, in particular soil-based ecosystem functions, are related to biodiversity. However, how plant species diversity influences soil-based functions along post-agricultural secondary succession is still a largely ignored question in Mediterranean semi-arid conditions. Therefore, we used the plant functional group approach to investigate the relationships between plant species diversity indices and soil-based functions including microbial biomass carbon (MBC), basal respiration (BR) and carbon sequestration (CS) across three different stages of the vegetation succession corresponding to ~ five years after agricultural abandonment, ~ 15 years after abandonment, and oak forests which represent the terminal stage. We also tested if these relationships are supported by the niche complementarity and selection effect hypotheses. The results showed that soil-based functions significantly increased with time since abandonment as BR, MBC and CS increased respectively by 1.7, 1.5 and 2.7 times across the three successional stages. We also found strong correlations between the diversity indices and the soil-based functions BR, MBC and CS which were positive for richness (R 2 values: 0.75, 0.74 and 0.75) and Shannon diversity (R 2 values: 0.61, 0.58 and 0.61) but negative for evenness (R 2 values: 0.38, 0.38 and 0.36 for, respectively). Similarly, richness and Shannon diversity of the different plant functional groups positively correlated with soil-based functions. However, contrasted results were found for evenness which positively correlated with soil-based functions for perennial grass only. We suggested that increasing the diversity of plant species and facilitating dominant species would be needed to improve the soil-based ecosystem functions after abandonment of degraded soils. This study also revealed that the mechanisms behind the relationships between biodiversity and ecosystems functions were influenced by the vegetative forms. Keywords Carbon sequestration. Cropland abandonment. Land use change. Richness. Semiarid forest Highlights  Species diversity and soil-based functions improve along the successional stages after land abandonment  The relationships between plant diversity and soil-based functions are influenced by the plant functional groups..  Niche complementarity plays a more vital role in soil-based ecosystem functions than the selection effect.
