... Ecological management aimed at improving the quality of land use involves the transformation of grasslands into forests. The water conservation capacity (WC) of forests per square kilometer exceeds 600 mm, whereas that of grasslands is approximately 192 mm, and arid lands can result in a loss of approximately 300 mm of their WC [80]. ...

... The phosphorus content in the area was really low (Fig. 3). It could be due to the low pH levels (Han et al. 2020), which can lead to a lot of exchangeable Al and Fe ions, as well as phosphate ions getting adsorbed by clay minerals (Buczko et al. 2018;Hou et al. 2014) and crop residue removal (He et al. 2023). Temperature is another factor that affects how much phosphate is available, and elevation and slope can play a role too-higher areas can lose phosphorus through soil erosion, making it more concentrated in the lower areas (Liu et al. 2013;Mardamootoo et al. 2021). ...

... Although 1 O 2 and⋅OH are reported that show dominating role in some special catalysis systems, more information on selective formation of other ROS is still needed to be revealed [22,23]. Otherwise, another overlooked problem is that sulfate anions inevitably generate and remain in the effluent in the concentration of hundreds mg L − 1 , causing potential risk for ecologic environment [24,25]. There is lack of solid evidence to support what controls the mechanisms of ROS formation, and how to alleviate the inorganic pollution from PS decomposition. ...

... Artificial aging (0 to 8 days, 45 °C, 100% relative humidity) applied on G. max seeds decreased the content of many phenolic compounds, including protocatechuic acid, morin and rutin and downregulated the expression of genes encoding key enzymes for the biosynthesis of phenolic compounds [43]. Decreased antioxidant activity was also detected in canola (Brassica napus) seeds stored underground for up to several months in association with a loss of seed vigor, a reduction in soluble sugars and hormonal alterations [64]. On the other hand, artificial aging in canola seeds enhanced enzymatic and non-enzymatic antioxidant capacity, including the content of phenolic compounds, flavonoids and flavonols [65]. ...

... Second, the areas in the upper Dadu River, from Danba, across Jinchuan to W. Barkam, are part of a unique geographical region known as the 'dry-hot valley', characterized by high temperatures and low humidity (Y. Yang et al. 2022) (Fig. 5). Consequently, this new subspecies, driven by such ecological opportunity, may have emerged in the dry-hot valley of the upper Dadu River, probably a case of the early stage of budding speciation (Funk & Omland 2003). ...

... A significant step towards sustainable mining is the non-traditional use of underground mines and surrounding land [24], such as energy storage [25,26], domestic and industrial waste disposal [27], parking systems in vertical wells [28,29], scientific experimentation facilities [30], underground agriculture [31], underground ecological cities [32], and rehabilitation of underground mines for tourism and recreational purposes [33]. ...

... Conversely, in both cultivars studied, NPs generally inhibited shoot elongation when incorporated into the alginate bead matrix. The observed dichotomy may be attributed to differences in the microenvironment as described by Tan et al. [46]. The microenvironment provided by the alginate bead matrix differs from the preculture medium in terms of physical structure, nutrient availability and water retention. ...

... Factors affecting the impact of crop residue removal on soil P loss risk include soil physical structure, chemical composition, treatment duration, and removal rate [27]. Despite previous studies examining soil aggregate structure and chemical components, little research has been conducted on the elemental content of different-sized soil aggregates [28], thereby making it difficult to determine an optimal removal rate strategy [29,30]. ...

... Transition metal (TM) activation has attracted significant attention due to its low cost and convenient operation [20,21]. Typical TM materials commonly used as oxidant activators include iron, cobalt, manganese, and copper, among which Fe-based materials have been the most favored due to their advantages of non-toxicity, low cost and high efficiency [18,20,22,23]. With growing attention, researchers discovered that high-valent metaloxo species (HVMSs, e.g., Fe(IV)/Fe(V), Co(IV), Mn(V)/Mn(VI), Cu(III), Ni(IV)), other than long-recognized radical species, dominate the effective degradation of organic compounds in certain TM-mediated catalytic processes. ...

... Therefore, the higher soil microbial biomass carbon content under N135R2 and N135R3 treatments during the flowering stage was beneficial to improve soil nutrient availability and provide sufficient nutrients for rapeseed reproductive growth. Soil urease activity is one of the important indicators of soil nitrogen supply intensity [31]. Nitrogen fertilizer can significantly increase soil urease activity, and an appropriate N application can keep the balance of N input and output. ...
