“…GRSP is the part of the contribution to SOC and positively correlated with the content of SOC (Rillig et al 2003, Singh et al 2016. GRSP can indirectly increase the content of SOC, thus jointly improve the stability of aggregates and enhance resistance to soil erosion (Rillig et al 2003, Zhu et al 2019. Besides binding agents in the soil physicochemical process, SOC also acts food and energy source for the soil microbial community.…”

Atrazine is still widely used in China. Atrazine residue (1.86–1 100 mg/kg) in the soil has exceeded the allowable limit (1.0 mg/kg), affecting soil structure and soil aggregate composition. To understand the long-term application of atrazine on soil aggregates and the binding agent, four treatments were established in cornfield planted since 1998, including without atrazine applied (AT0), atrazine applied (28% atrazine, 1 200–1 350 mL/ha/year) once a year from 2012 to 2018 (AT6, 167 mg/kg), from 2008 to 2018 (AT10, 127.64 mg/kg) as well as from 2002 to 2018 (AT16, 102 mg/kg) with three replications. Along with the increase of atrazine application time, the mass fraction of soil aggregates > 5 mm and 2–5 mm decreased significantly while the mass fraction of soil aggregates 0.5–2 mm and < 0.5 mm increased gradually, and the change of aggregate binding agents contents were the same as that of aggregates. The contents of soil organic carbon (SOC) and glomalin-related soil protein (GRSP) in the aggregates > 5 mm and 2–5 mm were significantly negatively correlated with the years of atrazine application. Our results show that although atrazine residue in the soil does not increase with the increased yearly application, its concentration is still markedly higher than the permitted limit value and seriously affected the content of SOC and GRSP of aggregates > 2 mm, which can lead to a decrease of soil aggregate stability and soil quality.

“…Reduced activities of soil fungi could diminish the production of polysaccharose and glomalin-related soil protein (GRSP) from the fungal hyphae, hence inducing the proportions of soil macroaggregates decreased (Ji et al, 2019). Likewise, as per our past studies (Wang et al, 2017b;Zhu et al, 2019), soil microbial activities and GRSP content served as the vital effects in the formation and stabilisation of soil macroaggregates, and presented the higher levels in the topsoil compared with the subsoil in tea plantation ecosystems. With increasing soil depth, the decrease in MWD value (Figure 1) was mainly related to the change of soil aggregate composition, especially for the decomposition of coarse macroaggregates into microaggregates, implying that the topsoil exhibited stronger aggregate stability in contrast to the subsoil.…”

Abstract. Soil ecological stoichiometry offers a sort of effective way to explore the distribution, cycling, limitation, and balance of chemical elements in tea plantation ecosystems. This study was aim to explore how soil organic C (OC) and nutrient contents (total N (TN), total P (TP), Ca2+, Mg2+, Fe2+, and Mn2+) as well as their stoichiometric ratios (C / N, C / P, N / P, Ca / Mg, and Fe / Mn) vary with tea-planting age (8, 17, 25, and 43 years) and soil depth (0–10, 10–20, 20–40, and 40–60 cm) at the aggregate scales in the southern Guangxi of China. Our results showed that tea-planting age and soil depth significantly influenced soil stoichiometric characteristics in various sized aggregates. In different aged tea plantations, soil OC, TN, and TP contents as well as C / N, C / P, and N / P ratios significantly decreased as the soil depth increased. In addition, soil Ca2+ and Mg2+ contents were significantly lower in the surface soil layer than the deeper soil layer, whereas soil Fe2+ and Mn2+ contents showed totally opposite trends, and no significant differences were detected among different soil depths in Ca / Mg and Fe / Mn ratios. Tea-planting age could influence the variations in soil stoichiometric characteristics, but such effects were more obvious at the 0–40 cm soil depth in contrast to the 40–60 cm soil depth. At the 0–40 cm soil depth, continuous planting of tea was beneficial for the cumulation of soil OC, total N (TN), Fe2+, and Mn2+, whereas soil Ca2+ and Mg2+ were susceptible to leaching losses over time. Compared with other tea-planting regions in China, soil C / N ratio was higher in this tea-planting region, whereas soil C / P and N / P ratios were much lower, indicating the lower contents of soil OC and TN, especially the TN. Therefore, an appropriate increase in the amount of N fertilizer should be applied in this tea-planting region. During the process of tea planting, the losses of soil Ca2+ and Mg2+, especially the Ca2+ (as indicated by the decrease in soil Ca / Mg ratio), could lead to the soil acidification. Soil acidification could reduce Fe2+ absorption and enhance Mn2+ uptake by tea plant (as indicated by the increase in soil Fe / Mn ratio), thereby causing the aggravation of Fe2+ insufficiency and the emergence of Mn2+ toxicity to tea plant. Overall, this study improved the understanding of soil OC and nutrient dynamics in tea plantation ecosystems, and also provided supplementary information for soil ecological stoichiometry in global terrestrial ecosystems.

“…AMF also activates plants antioxidant mechanisms such as glutathione peroxidase (GPx), ascorbate peroxidase (APX), catalyzes (CAT), and SOD [85]. In addition, AMF mycelium releases a particular glycoprotein called glomalin-related soil protein (GRSP), which helps improve soil conditions by forming complexes with heavy metals, helping to accumulate soil particles, increasing organic carbon content, and resulting in carbon sequestration [35,38,87]. Zhang et al showed that AMF significantly increased the number of aggregates more prominent than 2 mm in contaminated soils [88]; a similar study also showed AMF-inoculation in Calcaric Regosol under drought stress, and proper irrigation increased the percentage of macro-particles larger than 5 mm [89].…”

The increasing expansion of mines, factories, and agricultural lands has caused many changes and pollution in soils and water of several parts of the world. In recent years, metal(loid)s are one of the most dangerous environmental pollutants, which directly and indirectly enters the food cycle of humans and animals, resulting in irreparable damage to their health and even causing their death. One of the most important missions of ecologists and environmental scientists is to find suitable solutions to reduce metal(loid)s pollution and prevent their spread and penetration in soil and groundwater. In recent years, phytoremediation was considered a cheap and effective solution to reducing metal(loid)s pollution in soil and water. Additionally, the effect of soil microorganisms on increasing phytoremediation was given special attention; therefore, this study attempted to investigate the role of arbuscular mycorrhizal fungus in the phytoremediation system and in reducing contamination by some metal(loid)s in order to put a straightforward path in front of other researchers.
