“…F I G U R E 6 PC1 (57.6% of the variation) and PC2 biplot (24.3% of the variation) dividing three land uses including cultivated rangelands (CR0), rangelands abandoned for 15 years (AR15), and rangelands abandoned for 40 years (AR40). Min-C, mineralization carbon; MWD, mean weight diameter; N, soil total nitrogen; SOC, soil organic carbon; UR, uncultivated rangelands [Colour figure can be viewed at wileyonlinelibrary.com] These findings are also consistent with the findings of Xu et al (2019) and Yao et al (2019).…”

This study investigated the change in soil organic carbon (SOC), soil labile carbon (C), soil total nitrogen (N), particulate organic carbon (POC), mineralizable soil C (Min‐C) in soil aggregate fractions, and soil particles size at 0–30 cm soil depth of the semi‐steppe rangelands in Central Iran (Sheida and Khargosh regions). The study used a fully randomized design with four land uses in the rangelands including covered with rainfed wheat (CR0), abandoned rangelands (ARs) for 5–15 years (AR15), abandoned rangeland for 16–40 years (AR40), and permanently uncultivated rangelands (UR) as the reference sites that were replicated three times (n = 3) with at most 2 km distance from each other in an area of 25 ha. For each treatment, the soil samples were randomly obtained at 0–30 cm soil depth in three replicated plots of 2 × 2 m using a core size of 7 cm in diameter. The samples were mixed to take a composite soil sample (12 soil samples in each region) in June 2018. The results indicated that soil POC is the most sensitive fraction for the identification of shifts in the total SOC after the cultivation cessation because by increasing the abandoned land and the cessation of cropland activities, the POC has also increased. In conclusion, after the cessation of rainfed cropping and the recovery of natural vegetation, the increases in soil microorganism activity can result in a higher nutrient cycling in the degraded rangeland ecosystems.

“…The use of grasses and legumes as cover crops is an effective strategy to increase total N in the soil (Figure 1a). This has been reported in various studies (Mitchell et al, 2017;Yao et al, 2019;Silva et al, 2020). However, the availability of inorganic N is low in grass systems with high C:N ratios in sandy soil with low organic matter (Figure 1b), as soil microorganisms immobilize N in the soil and cause carbon degradation of straw and roots of cover crops.…”

“…Further, study conducted in Canada revealed that increased temperature decreases SOC while increasing soil microbial activity [26]. Type of cultivated crop also affect the nutrient cycle in soil such as leguminous green manure cropping systems were found to increase nitrogen concentration and improve soil health [27]. However, previous research pointed out that the risk of nitrate leaching in crops fertilized with minerals or organic N is weather and soil dependent and this affects crop productivity [28].…”

Climate change and soil health are intertwined complex processes that affect each other. The aim of this review was to find out the impact of climate change on soil health, its implication on food security and human welfare across the globe. The study found out that soil health is affected by land use practices and several anthropogenic activities carried out on landscapes; climate change and variability. Soil health also contributes to soil water retention, crop productivity, households’ food and income security culminating into a large contribution towards achieving sustainable development goals across the globe. Soil components affect climate and climate affects soil health and human wellbeing. The review article concluded that climate change and soil health are complex and intertwined multidisciplinary processes that require multidisciplinary approaches for better understanding and improvement of crop production. Appropriate climate smart agricultural practices are recommended to enhance soil health and mitigate and adapt to the changing climate for the improved farmers’ income, food security and human wellbeing across the globe.
