Research about farmland pollution by heavy metals/metalloids in China has drawn growing attention. However, there was rare information on spatiotemporal evolution and levels of metals the major grain-producing areas. We extracted examined data from 276 publications between 2010 2021 covering five regions to 2021. Spatiotemporal characteristics main obtained meta-analysis. In addition, subgroup analyses were carried out study preliminary correlations related accumulation pollutants. Cadmium (Cd) found be most prevailing pollutant terms both spatial distribution temporal accumulation. The Huang-Huai-Hai Plain severely polluted. Accumulation Cd, mercury (Hg) copper (Cu) increased 2015 when compared with 1990 background data. Further, key (Cd, Cu, Hg, lead [Pb] zinc [Zn]) showed increasing trends 2016 all regions. Soil pH mean annual precipitation had variable influences metal Alkaline soil areas less rainfall faced higher levels. Farmlands cropped mixed species smaller effect sizes than those single upland crop, suggesting that use patterns could alleviate soil. Of various remediation efforts, projects only held a small market share. findings are important support research risk assessment, regulatory development, prevention, fund allocation actions.

Super absorbent polymer (SAP) is well recognized to be one of the potential technologies for improving crop yields and water productivity (WP). However, effects SAP on WP remain inconsistent vary with environment application conditions. In this work we conducted a meta-analysis 1504 paired data points from 310 papers published before July 2022 evaluate effect yield considering attributes, initial soil properties, experimental The addition resulted in average increases 12.8% 17.2% respectively. Increases after were highest tuber crops, while greatest economic benefits observed vegetable crops. increase was higher rainfed conditions (18.3%) than irrigated (14.8%). improvement organic-inorganic hybrid compound types, banding/hole method, fine-grained structure. effectiveness response significantly positively correlated pH bulk density, negatively N fertilizer rates, supply, organic matter (SOM) total nitrogen. closely related increased stable aggregates (WSA), porosity, SOM, available nitrogen, phosphorus potassium application. These results suggest that are dependent properties. By integrating impacts environmental conditions, our findings can help tailor-make measures different fully achieve

Enhancing soil organic carbon (SOC) sequestration and food supply are vital for human survival when facing climate change. Site-specific best management practices (BMPs) being promoted adoption globally as solutions. However, how SOC crop yield related to each other in responding BMPs remains unknown. Here, path analysis based on meta-analysis machine learning was conducted identify the effects potential mechanisms of relationship between responds site-specific China. The results showed that could significantly enhance maintain or increase yield. maximum benefits (30.6%) (79.8%) occurred mineral fertilizer combined with inputs (MOF). Specifically, optimal would be achieved areas were arid, pH ≥7.3, initial content ≤10 g kg-1 , duration >10 years, nitrogen (N) input level 100-200 kg ha-1 . Further revealed original change an inverted V-shaped structure. association changes might linked positive role nutrient-mediated effect. generally suggested improving can strongly support better performance. Limitations increasing still exist due low level, regions where excessive N inputs, inappropriate tillage is inadequate diminished by optimizing harmony conditions.

Abstract Maintaining or even increasing crop yields while reducing nitrous oxide (N 2 O) emissions is necessary to reconcile food security and climate change, the metric of yield‐scaled N O emission (i.e., per unit yield) at present poorly understood. Here we conducted a global meta‐analysis with more than 6000 observations explore variation patterns controlling factors for maize, wheat rice associated potential mitigation options. Our results showed that average across all available data followed order (322 g Mg −1 , 95% confidence interval [CI]: 301–346) > maize (211 CI: 198–225) (153 144–163). Yield‐scaled individual crops were generally higher in tropical subtropical zones temperate zones, also trend towards lower intensities from low high latitudes. This was better explained by climatic edaphic fertilizer management, their combined effect predicted 70% variance. Furthermore, our analysis significant decrease use efficiency production systems cereal >10 ha (maize), 6.6 (wheat) 6.8 (rice), respectively. highlights indicators can be used as valuable proxies reconciling trade‐offs between mitigation. For three major staple crops, fertilization up 30%, optimizing timing placement application using enhanced‐efficiency fertilizers significantly reduced similar yields. data‐driven assessment provides some key guidance developing effective targeted adaptation strategies sustainable intensification production.

Non-continuous flooding is an effective practice for reducing greenhouse gas (GHG) emissions and irrigation water use (IRR) in rice fields. However, advancing global implementation hampered by the lack of comprehensive understanding GHGs IRR reduction benefits without compromising yield. Here, we present largest observational data set such effects as yet. By using Random Forest regression models based on 636 field trials at 105 globally georeferenced sites, identified key drivers non-continuous practices mapped maximum or under optimal strategies. The results show that variation are primarily explained UnFlooded days Ratio (UFR, ratio number standing to total growing period). could be feasible adopted 76% harvested areas. This would reduce warming potential (GWP) CH4 N2 O combined from production 47% GWP 7% alleviate 25%, while maintaining yield levels. UFR targets far exceed currently observed levels particularly South Southeast Asia, suggesting large opportunities climate mitigation conservation, associated with rigorous cultivation.
