“…High soil moisture favours the accumulation of chemical elements (e.g., C and N) rather than decomposition, especially under anaerobic conditions. Additionally, soil moisture has been reported to facilitate plant production and, consequently, enhance nutrient contents [41,42]. However, at the same depth in cluster 2, Lat was observed to be the most important controlling factor.…”

The effects of environmental factors on topsoil nutrient distribution have been extensively discussed, but it remains unclear how they affect spatial characteristics of soil carbon (C), nitrogen (N), and phosphorus (P) stoichiometry at different depths. We collected 184 soil samples in the typical black soil region of northeast China. Ordinary kriging was performed to describe the spatial distribution of soil C, N, and P eco-stoichiometry. Redundancy analysis was used to explore relationships between C:N:P ratios and physicochemical characteristics. The soil classification was studied by hierarchical cluster analysis. The mean C, N, and P contents ranged from 15.67 to 20.08 g·kg−1, 1.15 to 1.51 g·kg−1, and 0.80 to 0.90 g·kg−1 within measured depths. C, N, and P concentrations and stoichiometry increased from southwest to northeast, and the Songhua River was identified as an important transition zone. At 0–20 cm, soil water content explained most of the C, N, and P content levels and ratios in cluster 1, while latitude had the highest explanatory ability in cluster 2. For 20–40 cm, soil bulk density was the main influencing factor in both clusters. Our findings contribute to an improved knowledge of the balance and ecological interactions of C, N, and P in northeast China for its sustainability.

“…The determination of total nitrogen (TN) was tested by the Kjeldahl approach [32]. The nitrate nitrogen (NO 3 − -N) and ammonia nitrogen (NH 4 + -N) in the soil were extracted with 2 M KCl, and the contents of nitrate nitrogen and ammonia nitrogen in the filtrate were determined by continuous flow automatic analyzer (Alliance-Futura, France) after filtration [33]. The samples were digested in a H 2 SO 4 -H 2 O 2 mixture at 360 • C [34], after which total phosphorus (TP) was measured colorimetrically using an automatic discontinuous chemical analyzer (AMS Smartchem600, Beijing, China).…”

Plant-associated endophytic microorganisms are essential to developing successful strategies for sustainable agriculture. Grazing is an effective practice of grassland utilization through regulating multitrophic relationships in natural grasslands. This study was conducted for exploring the effects of grazing on the diversities and communities of bacteria and fungi presented in rhizosphere soils, roots, stems, and leaves of Leymus chinensis (L. chinensis), based on high-throughput sequencing. Grazing increased bacterial diversity but reduced fungal diversity in plant leaves. Further analysis confirmed that the abundance of Chloroflexi, Gemmatimonadota, Nitrospirota, Sordariales, and Pezizales in plant leaves was increased by grazing. The Bray–Curtis similarities of microbial communities in the endosphere were higher under grazing plots than non-grazing plots. Moreover, the bacterial communities were significantly correlated with ions, while the nutrient and negative ions exhibited strong influence on fungal communities. We concluded that grazing-induced changes of microbial diversities and communities in different compartments of a dominant perennial grass (L. chinensis) could be attributed to the nutrient and ion distribution in host plant. The current study highlights the importance of livestock in mediating diversities and communities of endophytic microbes, and will be useful for better understanding the complexity of multitrophic interactions in a grassland ecosystem.

“…dintanensis plantation may be related to the soil nutrient and water deficiency in this area, which affects the nutrition absorption and utilization of the plant root system. The latest research has shown that the soil stoichiometric characteristics will change under the condition of flooding (Li et al., 2020), suggesting that the long‐term drought environment may be one of the factors that kept the soil stoichiometric characteristics unchanged. However, the variation of stoichiometric characteristics of litter and leaves in different plantation ages indicated that there were differences in nutrient uptake and circulation rates of Zanthoxylum planispinum var.…”

The stoichiometry characteristics of Zanthoxylum planispinum var. dintanensis in different plantation ages (5, 10, 20, and 30 yr) in the canyon area of Guizhou Karst Plateau were studied by measuring the C, N, and P content of leaves, litter, and soil. The content of C, N, and P in leaves were 339.17−386.14, 20.95−23.65, and 1.18−1.72 g kg −1 , respectively. Carbon and P increased gradually with the plant age, but N did not change significantly. The growth of leaves changed from P restricted to N restricted. Those facts indicate that the main factors of nutrition restriction vary with plantation age. The change of C in litter was not significant with the plantation age. The highest content of N and P were in the 20-yr plantation. By increasing the decomposition rate of litter, Zanthoxylum planispinum var. dintanensis can adapt to the vulnerable habitat of the area. The content of C, N, and P in soil and the stoichiometric characteristics did not change significantly with the plantation age in spite of the overall P deficiency. The correlation of C, N, and P content in leaves, litter, and soil continuum of Zanthoxylum planispinum var. dintanensis plantation was low, and there was no significant interaction and interference, suggesting that the relationship of nutrient inheritance between the continuum of plantation needs further study. The results can set up a theory foundation for the Zanthoxylum planispinum var. dintanensis plantation nutrition management and ecosystem regulation and provide scientific basis for ecological construction and vegetation reconstruction in the canyon area of the Karst Plateau.
