“…Meanwhile, nitrogen (N) and phosphorus (P) are critical control factors for the growth of plants (Krouk & Kiba, 2020). The relationships among the three different elements are coupled (Bai et al, 2020). Soil C‐N‐P stoichiometric ratios indicate not only equilibrium of soil C, N, and P but also soil fertility during Chinese fir planting.…”

Soil C‐N‐P stoichiometry offers an effective way to explore the balance, limitation, cycling, and distribution of chemical elements in Chinese fir plantations. This research aimed to explore how soil organic C (Corg), total N (Ntot), and total P (Ptot) contents and stocks, together with their stoichiometric ratios vary with stand age (3, 9, 17, and 26 years) as well as soil layer (0–10, 10–20, 20–30, and 30–40 cm) at aggregate scales in Chinese fir plantations from Guangxi, China. For Chinese fir plantations of diverse ages, soil aggregate stability, Corg, Ntot, and Ptot contents and stocks, together with C/N, C/P, and N/P ratios, remarkably declined when soil depth increased. Stand age could influence C‐N‐P stoichiometric characteristics in soil, but such effect was more obvious in soil depth of 0–30 cm in comparison to that of 30–40 cm. In 0–30 cm soil layer, Corg and Ntot contents and stocks, together with C/P and N/P ratios, first rose and then reduced during Chinese fir planting; meanwhile, the highest levels could be observed in the 17‐year‐old Chinese fir plantations. However, Ptot content and stock, together with C/N ratio, were not related to the stand age. Overall, the present research helped to understand soil C, N, and P dynamics within a chronosequence of Chinese fir plantations. Also, it provided supplementary information for soil ecological stoichiometry in global terrestrial ecosystems.

“…However, most soil microbiome studies either do not include soil physicochemical properties or limit measurements to pH, soil organic carbon (SOC), total nitrogen (TN), total carbon (TC), moisture, and/or temperature, which do not fully reflect the complex soil chemical matrix and its various constituent elements (e.g., N, C, K, P, Zn, Fe, Ca, Mn, Mg). Soil properties vary with soil depth [ 22 ], as shown for SOC, total N [ 23 , 24 ], and total P [ 25 ]. Moreover, soil properties, particularly pH, are dynamic and fluctuate with changes in climate [ 26 ], environment [ 27 ], and the aboveground population [ 28 ].…”

Soil microbial communities are essential components of agroecological ecosystems that influence soil fertility, nutrient turnover, and plant productivity. Metagenomics data are increasingly easy to obtain, but studies of soil metagenomics face three key challenges: (1) accounting for soil physicochemical properties; (2) incorporating untreated controls; and (3) sharing data. Accounting for soil physicochemical properties is crucial for better understanding the changes in soil microbial community composition, mechanisms, and abundance. Untreated controls provide a good baseline to measure changes in soil microbial communities and separate treatment effects from random effects. Sharing data increases reproducibility and enables meta-analyses, which are important for investigating overall effects. To overcome these challenges, we suggest establishing standard guidelines for the design of experiments for studying soil metagenomics. Addressing these challenges will promote a better understanding of soil microbial community composition and function, which we can exploit to enhance soil quality, health, and fertility.

“…Soil stoichiometric ratio (C : N,C : P , N : P) not only represents the equilibrium features of Soil C, N and P but also takes into account the fertility characteristics, [79] reflecting nutrient cycle characteristics in micro soil environments [78] in the soil formation processes. Our result showed significant differences only in C : N, N : P and C : K. The average C : N in Indian soil was 11.20 whereas in China it was 10.52.…”

The effects of tea plantations upon soil are of great concern in the context of monoculture crops due to their increasing demand resulting in the expansion of tea growing areas. Therefore, this study was conducted to understand the soil’s Physico-chemical properties, soil nutrient concentrations, and stoichiometry in major tea-growing areas of India and China. For this study Meta-analysis approach was used to examine the difference between the two countries. Soil pH tends to be more acidic in Chinese soil (CS) than in Indian Soil (IS), soil Bulk Density (BD) was higher in CS with low soil Total Porosity (TP). Whereas the soil texture in CS was fine texture with Silt Clay while IS texture was coarse with sandy clay loam. Soil Carbon (C) showed no significant difference; while Nitrogen (N) concentration showed a significant difference only at the top layer with a higher concentration in IS. Soil Phosphorus (P) and Potassium (K) concentration were significantly higher CS than IS at all soil depths. The C: N ratio in both the countries was below 10 showing the accumulation of organic matter is low whilst the C: P ratio showed net mineralization of nutrients in both the countries. The N: P ratio represented N limitation in CS while P limitations in IS. The comparison of soil physical-chemical properties between India and China revealed the distinct differences between the tea plantation soils in both of these countries. Except for C concentration C: P, N: K, and P: K ratio all the properties are deemed to be different. Our results suggest that a balanced fertilizer application and these N and P limitations in tea growing soil of these two countries should be paid more attention to.
