“…Scores of the intervals of values for the different parameters and biological fertility index under conventional tillage (CT) and notillage (NT) practices at two different soil depths (0-20 and 20-40 cm) first reflected mostly in the surface soil layer as compared to deeper layers. Similar findings were presented byHao et al (2019) who compared two different soil depths of 0-15 and 15-30 cm.…”

Agricultural soil deterioration and land degradation have occurred over recent centuries in Mediterranean area, due to land conversion and intensive management practices; Basilicata region (Southern Italy) is a typical example of such changes (Kelly et al., 2015). In particular, scrublands and badlands have been converted to farmlands for durum wheat production in this area over the last three decades (Rinaldi, Scalcione, Perniola, Maddaluni, & Garofalo, 2017). However, efforts for replacing intensive management practices with no-tillage and crop residue

“…Increasing MBC is the consequence of high-concentration C substrates available to the soil microbial communities [36] and of a significant positive trend in the quantity of organic C in the natural or low-disturbance ecosystems over the long run [12], such as the grass-covered vineyard in the present research. Similarly, an increase in MBC has already been found with decreased levels of human activities i.e., no-tillage practices [37] and straw returning [38] by changing the soil physicochemical environment, such as soil water content, porosity, and bulk density.…”

“…Similarly, Li et al [62] and Malik et al [40] reported that the SOM significantly correlated with MBC in different land use. It has also been reported that soil microbial communities were affected by quality and quantity of soil organic carbon [38]. Van Wesemael et al [41] reported that the high qCO 2 values represent the high energy required to keep up the microbial biomass and indicate a stressful condition for microbial communities.…”

Soil Biological Fertility and Bacterial Community Response to Land Use Intensity: A Case Study in the Mediterranean Area

et al. 2019

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.

“…Changes in the soil environment induced by fertilization, tillage practice, and irrigation affect SIC stocking. Dong et al (2017) and Eshel et al (2007) noted that cultivation practices decrease SIC, where cultivation practice disturbs calciferous soils and transports SIC into rivers and lakes, deeper soils, and groundwater through irrigation and rainfall [4,84]. Ma et al (2013) and Zamanian et al (2016) argued the improvement in soil sodic and alkali conditions after long-term crop cultivation has triggered SIC loss [32,85].…”

“…Soil organic carbon (SOC) is one of the main focuses of studies because of its vital role in regulating ecosystem function and greenhouse effects. SOC mainly is produced from root exudates and the decomposition of litter and crop residues [3][4][5]. The progress is susceptible to cultivation practices, which adjust soil environments, i.e., the soil pH, soil water content, enzyme activities, and soil microbes [6][7][8][9].…”

Soil organic carbon (SOC) and soil inorganic carbon (SIC) play essential roles in carbon cycling in terrestrial ecosystems; however, the effects of crop cultivation on them are still poorly understood, especially in alkali sodic soils widely distributed in semiarid regions. Alkali sodic soils from cornfields and paddies with cultivation years of 5, 15, and 25 were analyzed here to assess the response of soil properties and soil carbon pools to crop cultivation. Soil pH and exchangeable sodium percentages decrease in accordance with cultivation years, while enzyme activity (amylase, invertase, and catalase) shows a contrary trend. Soil pH and exchangeable sodium percentages are negatively correlated with SOC, but positively correlated with SIC. Redundancy analysis reveals an obvious relationship between SOC and invertase activity. The percentage of δ 13 C SOC found here is approximately -24.78% to -22.97% for cornfields and approximately -26.54% to -23.81% for paddies, suggesting that crop cultivation contributes to SOC sequestration and stocking, increasing with cultivation years. The percentage of δ 13 C SIC found here is approximately 1.90% to 3.73% , proving that lithogenic inorganic carbon is the major SIC, where the stock decreases with increasing cultivation years. Significant total carbon stock loss is observed in cornfields, while it is preserved at 120 Mg ha −1 in paddies. We conclude here from the results that corn and rice cultivation reduce alkali sodic conditions in soil, thereby improving soil enzymes and favoring SOC stocking, but reducing SIC stocks.
