“…Given that 7.3 million hectares of vineyards are planted in China, it is crucial to reveal the effects of long-term monoculture on the soil biochemical indices for improving the sustainable cultivation of wine grapes. SEA regulated the essential metabolic pathways of soil microorganisms and was frequently employed to characterize the soil quality and the diversity of the functional soil microbial communities ( Zhang C. et al, 2019 ; Piotrowska-Długosz et al, 2022 ). Overall, the activities of the enzymes included in this study enhanced markedly after land use but were inversely proportional with the planting years, which was consistent with previous studies ( Liu et al, 2021 ).…”

“…Secondly, the degradation products such as pesticides, disinfectants, and insecticides used in agronomic management inhibited the SEA ( Niemi et al, 2009 ; Gao et al, 2020 ). Third, long-term monoculture may alter the diversity and composition of soil microbes, resulting in variations in microbial metabolic pathways and thus affecting enzyme activity ( Piotrowska-Długosz et al, 2022 ). Urease is an enzyme that is closely associated with nitrogen metabolism and catalyses the breakdown of urea into ammonia and carbon dioxide ( Zhang et al, 2013 ).…”

IntroductionContinuous cropping affected the stability of soil enzyme activity and the structural characteristics of microbial community. Owing to challenges in the study of complex rhizosphere microbial communities, the composition and function of these microbial communities in farmland ecosystems remain elusive. Here, we studied the microbial communities of the rhizosphere of wine grapes with different years of continuous cropping and investigated their relationships with soil enzyme activity.MethodsMetagenomic sequencing was conducted on the rhizosphere soils from one uncultivated wasteland and four vineyards with varying durations of continuous cropping.ResultsThe predominant microbial were bacteria (98.39%), followed by archaea (1.15%) and eukaryotes (0.45%). Continuous cropping caused a significant increase in the relative abundance of Rhizobiales and Micrococcales but a marked decrease in Solirubrobacterales. At the genus level, 75, 88, 65, 132, and 128 microbial genera were unique to uncultivated wasteland, 5, 10, 15, and 20 years of continuous cropping, respectively. The relative abundance of genes with signal transduction function was the highest. The activity of all enzymes measured in this study peaked at 5 years of continuous cropping, and then decreased with 10 to 15 year of continuous cropping, but increased at 20 years again. In addition, soil enzyme activity, especially of alkaline phosphatase was significantly correlated with the diversity of the dominant microorganisms at the genus level. Moreover, the coupled enzyme activities had a greater impact on the diversity of the microbial community than that of individual enzymes.ConclusionOur findings reveal the composition and function of the soil microbial communities and enzymes activity in response to changes in cropping years, which has important implications for overcoming continuous cropping obstacles and optimizing land use.

“…In contrast, the oxidase activities were higher in the 40–60 cm soil layer than in other soil layers ( Table 3 ; Figure 4 ), which were consistent with the results obtained by Sinsabaugh (2010) and Mazzon et al (2018) , who suggested that the deep soil layers owned higher oxidase activities than the surface soil layers. These findings could be explained by the differences in the edaphic factors, e.g., pH, soil compactness, SOC characteristics, as well as in enzyme’s functions ( Piotrowska-Długosz et al, 2022 ). Zeglin et al (2007) and Burns et al (2013) revealed that oxidases mainly participated in stable C fractions decomposition and their activities could be inhibited by the higher N levels in soils.…”

Knowledge of the spatial–temporal variations of soil organic carbon (SOC) quantity and quality and its microbial regulation mechanisms is essential for long-term SOC sequestration in agroecosystems; nevertheless, this information is lacking in the process of walnut plantations. Here, we used the modified Walkley-Black method, phospholipid fatty acid analysis, and micro-plate enzyme technique to analyze the evolution of SOC stocks and quality/lability as well as microbial communities and enzyme activities at different soil depths in walnut plantations with a chronosequence of 0-, 7-, 14-, and 21-years in the Eastern Taihang Mountains, China. The results indicated that long-term walnut plantations (14-and 21-years) enhanced SOC stocks, improved SOC quality/lability (as indicated by the lability index), and promoted microbial growth and activities (i.e., hydrolase and oxidase activities) in the 0–40 cm soil layers. Besides, these above-mentioned SOC-and microbial-related indices (except for oxidase activities) decreased with increasing soil depths, while oxidase activities were higher in deeper soils (40–60 cm) than in other soils (0–40 cm). The partial least squares path model also revealed that walnut plantation ages and soil depths had positive and negative effects on microbial attributes (e.g., enzyme activities, fungal and bacterial communities), respectively. Meanwhile, the SOC stocks were closely related to the fungal community; meanwhile, the bacterial community affected SOC quality/liability by regulating enzyme activities. Comprehensively, long-term walnut plantations were conducive to increasing SOC stocks and quality through altering microbial communities and activities in the East Taihang Mountains in Hebei, China.

“…As depth increases, the aggregate stability decreases, which may be related to soil compaction and degradation at deeper layers [126][127][128]. An increased amount of total clay can be associated with the process of vertical translocation of particles in the soil [129][130][131], which results in greater amounts of clay negatively correlated with root development at the deeper layers evaluated. A loss of soil quality at increased depths was evidenced by cluster analysis, which defined a group formed by the data collected at 40-60 and 60-80 cm.…”

Studies on the development of the root system can provide important information about responses to different management strategies, such as the use of lower quality water, also evaluating the interaction between plants and the physical properties of the soil. This study tested the hypothesis that irrigation with treated sewage effluent (TSE) supplies the water needs of sugarcane plants, increasing root growth and improving the physical properties of the soil. We evaluated the effects of subsurface dripping with TSE or surface reservoir water (SRW) on the root development of first ratoon cane (Saccharum officinarum L.) and the physical properties of dystrophic red latosol. Irrigation treatments were applied at 20 and 40 cm and soil properties were evaluated at soil depth layers of 0–20, 20–40, 40–60, and 60–80 cm. We verified that under irrigation with TSE and SRW, shallower soil layers present better porosity, soil aggregation, and aggregate stability conditions, parameters that improve the root system development and plant growth. On the other hand, deeper soil layers have lower macroporosity and higher total clay volume, indicating the possibility of compaction and greater limitations for sugarcane root growth. These results are important for understanding soil quality and provide significant information for agricultural management and for the implementation of sustainable soil conservation practices. This study shows the efficiency of TSE as an alternative water source for sugarcane crops.
