Article
Plant invasion can change soil microbial function and nitrogen (N) supply through the input of litter with different qualities and quantities, among other factors. However, the underlying mechanism for litter quality to regulate soil N mineralization via microbial function with plant invasion remains unclear. We examined the effect of litterfall wi...
Chapter
Biochar (BC) is produced by pyrolysis process, i.e., when crop residues, biomass, grass, trees, or other plants are combusted at temperatures of 300–600 °C under anaerobic conditions; it enables the carbon in the biomass to resist decay. Biochar is used as an alternative organic source for the improvement of soil fertility, for the mitigation of GH...
Article
Nitrogen (N) fertilizer application is an essential part of agricultural production in order to improve rice yields. However, long-term irrational application and low utilization of N fertilizer have caused a series of environmental problems. Biofertilizer is considered an effective alternative to N fertilizer. In this study, the effect of bioferti...
Article
This study aims to explore the effect of loading metal ions on antibiotics adsorption by clay-based sulfonated solid acid. Bentonite (B) was continuously modified with nitric acid (N) and sulfuric acid (S) to obtain bentonite-based solid acid (NB) and sulfonated NB (SNB). SNB was loaded with Fe 2+ , Cu 2+ , and Mn 2+ to obtain Fe-loaded SNB (Fe-SNB...
Article
To explore the adsorption performance of antibiotics in different amphoteric clays loaded with magnesium (Mg) and dodecyl dimethyl betaine (BS) was used to modify bentonite (B), kaolin (K), and diatomite (D) to obtain different amphoteric clays (named as BS-B, BS-K, and BS-D, respectively). Then, Mg-loaded amphotropic clays (abbreviated as Mg-BS-B,...

Aims Potato starch wastewater contains higher contents of essential nutrients, which can be fertilizer to help crop growth. However, the effects of fermented potato fertilizer on soil ecology and microbial community structure have not yet been elucidated. This study aimed to investigate the shifts of active ammonia oxidation microbial communities u...

To realize simultaneous adsorption of heavy metal and antibiotic pollutants by a BC-based recyclable material, Fe 3 O 4 magnetic biochar (MBC) was prepared by co-precipitation method. Then different ratios of dodecyl dimethyl betaine (BS-12)-modified bentonite (BS-B) were loaded on the surfaces of biochar (BC) and MBC to prepare BS-B-loaded BC and...

Aims Potato starch wastewater contains higher contents of essential nutrients, which can be feritilizer to help crop growth. However, the effects of potato fermented fertilizer on soil ecology and soil microbial community structure have not yet been elucidated. The objective of this study was to investigate the shifts of active ammonia oxidation mi...

A pot experiment was carried out to study the response of Moso bamboo (Phyllostachys edulis) and broadleaf tree species (Schima superba, Cinnamomum camphora, Cyclobalanopsis glauca), representing respective native invasive and non-invasive plants in subtropical China, to N addition with three NH4+/NO3− ratios. We used 15N isotope tracing and high-t...

To explore the effects of modified pomace on copper migration via the soil on the banks of the rivers in northern Sichuan and Chongqing, fruit pomace (P) and ethylene diamine tetra-acetic acid (EDTA) modified P (EP) were evenly added (1% mass ratio) to the soil samples of Guanyuan, Nanbu, Jialing, and Hechuan from the Jialing River; Mianyang and Su...

Soil contamination poses a severe threat in terms of deteriorated environmental quality and badly influences human health. Agricultural soils, mainly in the suburban areas, need detailed investigations for their heavy metal contents to avoid food chain contamination. This study was done to examine the heavy metals (Cu, Ni, Pb, Cr, Zn, and Mn) enric...
Article
Cadmium (Cd) is the most concerning soil pollutant, and a threat to human health, especially in China. The in-situ immobilization of Cadmium by amendments is one of the most widely adopted methods to remedy soil contamination. The study was designed to evaluate the effect of organo-chemical amendments on soil Cd bioavailability and nitrogen cycling...

Anammox bacteria are the key microbes after denitrifiers in the anaerobic environment. Nitrogen gap cannot be satisfied till date even with the advanced techniques, due to complex microbial network and different pathways. Recently, anaerobic fungi are the concerning point to investigate, which was previously ignored for a long time. Study was condu...

Purpose Vegetables are major economic crops in China. Their cultivation usually involves high fertilizer application rates leading to significant losses of N and P to the wider environment, resulting in water contamination and low nutrient use efficiency. Hence, it is a matter of urgency to understand the mechanisms and factors that affect N and P...
Article
The bacteria-mediated anaerobic ammonium oxidation under iron reducing conditions, termed feammox, represents a process for alleviating N accumulation in anoxic soils. Fertilization, as an important agricultural strategy, needs to be investigated in order to determine its effects on nitrogen (N) removal via the feammox process in paddy soils. In th...
