Article
Despite plastics providing great benefits to our daily life, plastics accumulating in the environment, especially microplastics (MPs; defined as particles <5 mm), can lead to a range of problems and potential loss of ecosystem services. Current research has demonstrated the significant impact of MPs on aquatic systems, but little is known about the...
Article
Labile carbon (C) inputs to soil (e.g., litter and root exudation) can prime soil organic matter (SOM) decomposition, and strongly influence SOM dynamics. The direction and intensity of priming, as well as the net C balance in soil, depend on the amount and frequency of labile C inputs. Most recent priming studies are based on single C additions, w...

Diversified cropping systems, especially those including legumes, have been proposed to enhance food production with reduced inputs and environmental impacts. However, the impact of legume pre-crops on main crop yield and its drivers has never been systematically investigated in a global context. Here, we synthesize 11,768 yield observations from 4...
Article
Full-text available
Recycling of livestock manure in agroecosystems can promote resource utilization and reduce negative environmental consequences from intensive crop-livestock systems. However, the interaction effect of manure application and irrigation strategy on the water footprint (WF) of crop production still remains incomplete. Here, we estimated the WF of the...
Article
Full-text available
Many anthropogenic pressures are being exerted on terrestrial ecosystems globally, perhaps the most pressing of which include microplastics (MPs; <5 mm in size) pollution and climate change, both of which may have unpredictable consequences on soil ecosystem functioning. We therefore hypothesized that a dual pressure (MPs and warming) on plant-soil...
Article
Microplastic contamination poses a significant threat to agroecosystem functioning, provoking a move away from the use of conventional oil-based plastics in agriculture, to biodegradable alternatives that may be degraded over a shorter timescale. The impact of these bioplastics on plant and soil health, however, has received relatively little atten...
Article
Biodegradable mulch film potentially offers an encouraging alternative to conventional (petroleum-based) plastic films. Since biodegradable films are more susceptible to rapid degradation and more microplastics (MPs) might be generated than conventional films within the same time frame, probably leading to more severe MPs pollution and associated e...
Article
Full-text available
PurposeIncreasing crop yield to ensure global food security while decreasing carbon footprint (CF) is a challenge for sustainable agriculture. Although intercropping is suggested as a potential pathway in this regard, the balance between yield advantage and CF is unclear, especially under different nitrogen (N) application rates.MethodsA two-year f...
Article
Full-text available
Marginal land conversion to perennial energy crops can provide biomass feedstocks and climate change mitigation. However, the effect of perennial energy crop cultivation on soil organic carbon (SOC) sequestration and its underlying mechanism in marginal land still remains incomplete. Here, SOC turnover, stability, and its potential sequestration we...

Contemporary wisdom suggests that inclusion of legumes into crop rotations benefit subsequent cereal crop yields. To investigate whether this maxim was generically scalable, we contrast summer soybean–winter wheat (SW) with summer maize–winter wheat (MW) rotation systems in an extensive field campaign in the North China Plain (NCP). We identify her...

Soil aggregates not only store carbon (C) and nitrogen (N) but hold a critical role in determining the nutrients supply, crop productivity, and climate change mitigation. However, the impact of cropping system and N fertilization on aggregate-associated C and N in both topsoil and subsoil remains unclear. Here, we assessed the effect of cropping sy...
Article
Drained peatlands support highly profitable agriculture, but also represent a globally important source of greenhouse gas (GHG) emissions. Grasslands can typically be maintained at higher water levels than croplands, so conversion of cropland to grassland represents a potential CO2 mitigation strategy that allows for continued agricultural producti...

The responses of soil denitrifiers to inorganic and organic mixed fertilization in paddies have not been well evaluated. The abundance and diversity of nirS- and nirK-type denitrifiers in paddies after 30-year fertilization were estimated using quantitative PCR and Illumina MiSeq sequencing. The nirS gene abundances were two orders of magnitude hig...

Quantification of legume nitrogen (N) rhizodeposition (N derived from root) and its fate in agroecosystems is crucial for soil fertility, land productivity, and agricultural sustainability. In contrast to forage legumes, the N rhizodeposition by grain legumes is nearly unknown. Therefore, N rhizodeposition of four grain legumes and its transfer to...

Plant roots interact with rhizosphere microorganisms to accelerate soil organic matter (SOM) mineralization for nutrient acquisition. Root‐mediated changes in SOM mineralization largely depend on root‐derived carbon (root‐C) input and soil nutrient status. Hence, intraspecific competition over plant development and spatiotemporal variability in the...
