“…Soil multifunctionality was calculated based on SOC, TN, AN, AK, AP, URE, CAT and PRO. Values were firstly standardized (Z‐score transformation) and then averaged to acquire the SMF index using the following formula (Pan et al, 2022; Ren et al, 2018).

SMF goodbreak= \frac{1}{F} \sum_{i = 1}^{F} normalg ()(, italicri ()(, fi)) .

where F is the number of soil functions, f i is a measure of function i , r i is a mathematical function that turns r i into Z‐score, and g is a transformation that standardizes measures of the eight soil functions to the same scale.…”

Rice cultivation has been found to be an effective and feasible approach for improving saline soils and increasing food production. Most studies on the improvement of rice cultivation on saline soil have focused on the several individual soil properties in the topsoil, and we know little about the importance of rice cultivation for improving multifunctionality in coastal saline soils. We investigated basic soil properties (soil physical sand content, soil physical clay content, pH, EC, soil organic carbon, total nitrogen, alkaline hydrolysis nitrogen, available potassium, available phosphorus), enzyme activities (urease, catalase, protease) and soil multifunctionality (SMF) in 0–20 cm, 20–40 cm, 40–60 cm, 60–80 cm and 80–100 cm soil layers with rice cultivated for 0 (tidal flat; CK), 20 (R20), 44 (R44) and 70 years (R70). We found that soil EC was alleviated markedly in the first 20 years after rice cultivation. Soil physical sand content, pH, EC and available potassium (AK) decreased while total nitrogen (TN), alkaline hydrolysis nitrogen (AN), urease (URE), catalase (CAT) activities and SMF increased with the increase in rice cultivation years. The highest soil total organic carbon (SOC) was shown in R44. Soil pH, EC, AK and physical sand content increased while SOC, TN, AN, enzyme activities decreased with the increase in soil depth. Redundancy (RDA) analysis showed soil physicochemical properties explained 97.53% of the variation in soil enzyme activities. Soil CAT, URE and protease (PRO) had a positive correlation with soil physical clay content, SOC, TN, AN and AP while negatively correlated with pH and AK. The increased SOC and clay content by rice cultivation might be the main reasons stimulating soil enzyme activities. In summary, long‐term rice cultivation could alleviate soil salinity, increased SMF down to 1 m, implying that rice cultivation effectively improved coastal saline soil, and the improvement could last for 70 years.

“…Nutrient cycling: Microbial communities contribute to the decomposition of organic materials for certain nutrients to be produced and returned to the soil (Figure 1) which is added to the soil and utilized by plants. The microbial function hitherto is to decompose the organic material into simple utilizable forms for developing plants which improve soil fertility [17].…”

Alternatives are required to solve challenges encountered in the food security sector with the increasing global population due to ecological instability and changes observed in climate. Abiotic stress including high salinity and drought caused the degradation of soil thereby making it not fittable for agricultural practices to reveal the problem encountered. However, microbial communities including bacteria, fungi, and archaea have been proven to contribute to soil health, plant growth promotion, induce systemic resistance against diseases, and overall promote abundant production of agricultural products. These microbes also have the potential to control biotic and abiotic stresses and they are associated with improving climate-resilient soils. This review reveals the green and sustainable methods employed to combat soils encountering the problem posed by the change in climate and further reveals the potential of the microbes to stimulate the production of nutrients or elements required for agricultural sustainability, and also the beneficial value they add to the environment via biogeochemical cycle.

“…So far, the total area of Chinese fir plantations is about 9.9 × 10 6 ha, with a stock volume of 7.6 × 10 8 m 3 , ranking in first place among all plantations in the nation [28]. However, the soil quality and wood production of Chinese fir forests have declined sharply due to the monoculture cultivation and continuous cropping with insufficient fallow periods [30,32]. Therefore, various afforestation strategies have being actively explored to maintain the soil quality and ecosystem sustainability of Chinese fir forests to meet the challenges of global climate change [33,34].…”

To assess the alterations in soil properties resulting from the interplanting of broad-leaved tree species within coniferous forests, we conducted an investigation into soil quality in a mixed Chinese fir and broad-leaved forest, as well as in a Chinese fir pure forest (used as a control) in subtropical China. A total of 15 soil physicochemical properties were assessed across three soil depths—0–15 cm, 15–30 cm, and 30–45 cm—for the two forest types in the experimental study. Principal component analysis in conjunction with the Norm value was employed to create a minimal data set (MDS) for assessing six indicators, including bulk density (BD), total nitrogen (TN), total phosphate (TP), available potassium (AK), soil pH, and catalase (CAT). The soil quality index (SQI) was calculated for both forest types. The results demonstrated that following the interplanting of broad-leaved tree species in the Chinese fir forest, all soil physicochemical indicators were significantly improved compared to the control, and significant differences were also observed in the 0–15 cm and 15–30 cm soil layers (p < 0.05). The overall average of the SQI of the mixed forest (0.8523, 0.6636) was significantly higher than that of the control (0.4477, 0.3823) (p < 0.05) in the 0–15 cm and 15–30 cm soil layers, respectively. However, there was no significant difference in the SQI in the 30–45 cm soil layer (p > 0.05) between the two forest types. The results indicated that the SQI based on the minimal dataset (MDS) can reflect the SQI of the total dataset (TDS) when assessing soil quality in forests. Our research provides valuable scientific insights into soil science and an understanding of the relationships between soil properties, forest structure, and species composition in sustainable forest management.
