“…The amendment of fertilizer plus lime increased the δ 15 N values of litterfall significantly (Figure 3; Table S4), similar to the studies of Raymond et al (2016) and Yan et al (2020) which was more pronounced for G. arborea than S. parahyba . This is again unexpected because of the low δ 15 N value of the N fertilizer of −0.30‰.…”

“…The litterfall of G. parahyba showed lower δ 15 N values in the dry than in the rainy season, both in the plots with mineral fertilizer plus lime (1.14-2.9‰ in the rainy season and 1.00-2.53‰ in the dry season) and without (1.09-3.52‰, 0.84-2.83‰), irrespective of the amendment of biochar. We attribute this to reduced leaching of isotopically light N from the leaves during the dry season (Amundson et al, 2003;Carroll et al, 2016;Schwarz et al, 2011;Yan et al, 2020). .…”

The use of biochar is expected to improve soil fertility and close nutrient cycles in degraded strongly weathered tropical soils. We, therefore, hypothesized that biochar amendment to tree plantations (a) increases nutrient fluxes with litterfall alone and with mineral fertilizer plus lime and (b) reduces N losses reflected by lower δ 15 N values of litterfall and soils than in unamended controls. We grew the native leguminous Schizolobium parahyba var. amazonicum (Ducke) Barneby and the exotic Gmelina arborea Roxb at two sites. We used a replicated full factorial split-split plot design of amendment of mineral fertilizer plus lime, 3 and 6 t ha −1 biochar, and a control. We collected litterfall biweekly (2012)(2013) and topsoil samples (0-0.25 m) in 2009 before tree planting, in 2011 and 2013. Fertilizer plus lime increased the mean annual concentrations of P, Ca and Zn in litterfall but decreased that of Mn. At the same time, fertilizer plus lime increased the annual fluxes of nutrients, Na and Al with litterfall. During the dry season, biochar decreased the N concentration in litterfall and the K flux with litterfall. During the rainy season, biochar increased the concentrations of Ca and Zn in litterfall and their fluxes with litterfall. Biochar did not influence the δ 15 N values of soil and litterfall after 51 months of tree growth. Fertilizer plus lime decreased the δ 15 N values of soil, because of the lower δ 15 N value of the used urea (−0.30‰) than the soil (4.5‰-7.8‰). Moreover, fertilizer plus lime increased the δ 15 N values of litterfall, possibly because of enhanced 14 N leaching from the N-rich canopies. The amendment of up to 6 t ha −1 biochar did not contribute to close nutrient cycles.

“…The samples were rinsed in the order of water, detergent, water, 1% hydrochloric acid and then three times with deionized water, after which they were dried at 105°C for 30 min, followed by drying at 80°C to a constant weight ( Zhang R. et al, 2021 ). The dried samples were ground through a 0.25 mm sieve and stored in plastic bags for determination of the 13 C and 15 N abundance of the plants ( Yan et al, 2020 ).…”

Malus sieversii grows on the slopes of the Tianshan Mountains in Xinjiang where the difference in daily temperature is significant. In recent years, the rhizosphere soil health of Malus sieversii has been severely impacted by anthropogenic disturbance and pathogenic infestation. The soil nutrient content and soil microorganism diversity are the main components of soil health. Low temperature has negative effects on soil bacterial community structure by inhibiting the accumulation of carbon and nitrogen. However, the effects of temperature and nitrogen application on soil carbon and nitrogen accumulation and the bacterial community composition in the rhizosphere soil of Malus sieversii are unclear. We set two temperature levels, i.e., low temperature (L) and room temperature (R), combined with no nitrogen (N0) and nitrogen application (N1) to explore the response of plant carbon and nitrogen uptake, rhizosphere soil carbon and nitrogen accumulation and bacterial community composition to temperature and nitrogen fertilization. At the same temperature level, plant 13C abundance (P-Atom13C), plant 15N absolute abundance (P-Con15N), soil 15N abundance (S-Atom15N) and soil urease, protease and glutaminase activities were significantly higher under nitrogen application compared with the no-nitrogen application treatment. The bacterial community diversity and richness indices of the apple rhizosphere soil in the N1 treatment were higher than those in the N0 treatment. The relative abundances of Actinobacteria, Rhodopseudomonas, and Bradyrhizobium were higher in the LN1 treatment than in the LN0 treatment. Redundancy analysis (RDA) showed that plant 13C absolute abundance (P-Con13C) and plant 15N absolute abundance (P-Con15N) were the main factors affecting the soil bacterial community composition. In summary, Nitrogen application can alleviate the effects of low temperature stress on the soil bacterial community and is of benefit for the uptakes of carbon and nitrogen in Malus sieversii plants.

Arbuscular mycorrhiza (AM) and ectomycorrhiza (ECM) are the two most common mycorrhizal types and are paid the most attention to, playing a vital common but differentiated function in terrestrial ecosystems. The leaf carbon isotope ratio (δ13C) is an important factor in understanding the relationship between plants and the environment. In this study, a new database was established on leaf δ13C between AM and ECM plants based on the published data set of leaf δ13C in China’s C3 terrestrial plants, which involved 1163 observations. The results showed that the differences in leaf δ13C between AM and ECM plants related closely to life forms. Leaf δ13C of ECM plants was higher than that of AM plants in trees, which was mainly led by the group of evergreen trees. The responses of leaf δ13C to environmental changes were varied between AM and ECM plants. Among the four life forms, leaf δ13C of ECM plants decreased more rapidly than that of AM plants, with an increase of longitude, except for deciduous trees. In terms of the sensitivity of leaf δ13C to temperature changes, AM plants were higher than ECM plants in the other three life forms, although there was no significant difference in evergreen trees. For the response to water conditions, the leaf δ13C of ECM plants was more sensitive than that of AM plants in all life forms, except evergreen and deciduous trees. This study laid a foundation for further understanding the role of mycorrhiza in the relationship between plants and the environment.
