“…The chamber lid was closed at the start of the sampling procedure, followed by sample collection every 20 min using a 20 mL polypropylene syringe. The gas sample was then transferred into a 12 mL evacuated glass vial (Exetainer, Labco, Ceredigeon, UK), as previously described [10,11]. N 2 O and CO 2 concentrations were measured using a gas chromatography-mass spectrometer (GC/MS, OP2020, Shimazu, Kyoto, Japan).…”

“…N 2 O and CO 2 concentrations were measured using a gas chromatography-mass spectrometer (GC/MS, OP2020, Shimazu, Kyoto, Japan). GC/MS conditions were maintained during the analysis, including a column temperature of 60 • C, heating temperature of 330 • C, and N 2 gas as a carrier [10,11]. For the calculation of gas flux, only 20 and 40 min gas sample concentrations were used because of asymptotic problems [10,29].…”

“…SM+FeO treatment showed the highest reduction efficiency for both N2O-N and CO2-C emissions. Greenhous gas (GHG) emissions in soil can be affected by various factors, such as soil pH, Eh, and ammonium nitrogen concentrations [10,11,29,44]. Soil acidification increases GHG emissions [5,45].…”

“…Various remediation techniques have been applied to reduce both heavy metal concentrations and GHG emissions in agricultural soil. The application of amendments is a popular technique used to immobilize bioavailable heavy metals and reduce GHG emissions in soil because of its high efficiency, low cost, and ease of use [10][11][12][13]. The most commonly used amendments include organic materials (biochar, compost, and plant residuals), minerals (zeolite), and pH adjusters (lime, steel slag, and coal ash) [2,3,14,15].…”

Heavy metal pollution and greenhouse gas (GHG) emissions from soil are two major detrimental sources in the agriculture environment because of concerns about crop safety and global warming. Applying amendments on site is a common technique used for heavy metal remediation and the reduction in GHG emissions. This study aims to evaluate the effect of different amendments on the reduction in both bioavailable heavy metals and GHG emissions from soil. Four different amendments, namely bottom ash (BA), sintered material (SM), sintered material combined with lime (SM + L), and FeO (SM + FeO) were applied to upland fields, followed by maize (Zea mays L.) cultivation from April to October. Subsequently, SM + FeO treatment demonstrated the highest bioavailability reduction efficiency for As at 79.1%, and SM + L treatment had a high efficiency for the reduction in Cd and Pb by 64.6% and 41.4%, respectively. SM + FeO treatment also reduced bioaccumulated As and Pb in maize grain by 59.3% and 66.2%, respectively. Furthermore, SM + FeO treatment demonstrated the highest reduction efficiency for cumulative N2O emissions by 70.7%, compared to the control soil. Among the four different amendments, the efficiency of heavy metal and GHG emission reduction was in the following order: SM + FeO > SM + L > SM > BA. Overall, SM combined with FeO is a promising amendment for reducing and managing both heavy metal pollution and GHG emissions in soil.

Healthy soil is essential for maintaining food security and enhancing ecosystem functions. Green manure application improves soil fertility and is an alternative to chemical fertilizers; however, research on optimizing soil health assessment systems and providing comprehensive and accurate information for local farmland green manure management models remains limited. In this study, we used maize and potato intercropped with green manure farmland in the main crop production area of a semi‐arid irrigation area in Northwest China as the research object, integrated the regional soil environment characteristics, and used principal component analysis and other methods to establish a minimum index data set including physicochemical, biological, and yield indices. A soil health assessment system applicable to the study region was constructed and optimized by drawing the scoring curve. The results showed that green manure treatment exerted a positive effect on the soil bulk density, nutrient content, extracellular enzyme activity, and the yield of maize and potato fields. This evaluation method showed that both green manure treatments could improve the soil health index of two major crop fields, with scores of 6.9 (3.7–8.6) and 6.2 (4.5–7.0) for maize and potato farmland, respectively, with a greater positive effect caused on maize. This evaluation system can not only reflect the soil conditions of farmland accurately given the application of green manure in the semi‐arid irrigation areas of northwest China but also provide reference for the promotion of organic fertilizers such as green manure and the resolution of regional soil health differences.
