Abstract:
... Livestock manure is often used as fertilizer in greenhouses, resulting in simultaneous enrichment of heavy metals and antibiotic resistance genes (ARGs) in soils. The soil-plant system is a non-negligible way to spread ARGs; however, the effects of lead (Pb) on the spread of ARGs and their driving factors in the greenhouse soil-plant system remain unclear. In this present study, the occurrence of ...

Abstract:
... Cauliflower-onion system is gaining popularity in urban and semi-urban areas due to various reasons. The nutrient management in the system mode of intensive vegetable production is crucial for better growth and higher vegetable productivity. Along with inorganic nutrient sources, integration with organic sources has been advocated for predominant systems. But the information regarding vegetable cr ...

Abstract:
... A high-performance nitrogen-doped lignin-based carbon material (ILAC-N) was synthesized using industrial lignin and urea by hydrothermal and activation, as an absorbent of tetracycline hydrochloride (TC). The results showed that the ILAC-N comprises a double-channeled structure with micro and mesopores. It exhibits an excellent adsorption capacity of TC across a wide pH range (pH 2–11), with the h ...

Abstract:
... Anaerobic digestion and composting are attracting increasing attention due to the increased production of animal manure. It is essential to know about the fate and bioavailability of heavy metals (HMs) for further utilisation of animal manure. This review has systematically summarised the migration of HMs and the transformation of several typical HMs (Cu, Zn, Cd, As, and Pb) during anaerobic diges ...

Abstract:
... Manure as a resource is a major issue in the agricultural sector. Mesophilic anaerobic fermentation is the most common treatment modality for livestock manure, but it cannot completely eliminate human pathogens. Recently several reports characterized bacteria and human pathogens after manure treatment by mesophilic anaerobic fermentation. In this study, we used high-throughput sequencing to analyz ...

Abstract:
... The emergence of plasmid-mediated tigecycline-resistant genes [tet(X3)to tet(X6)] in animals and humans has raised serious concerns over their possible cross-environmental dissemination. However, behavior of these emerging mobile tet(X)-variant genes in manure treatment processes, particularly for different composting treatments, has not yet been studied. Here, we explored the environmental behavi ...

Abstract:
... Slurry acidification is effective for reducing gaseous emissions during slurry storage. However, an alternative to sulfuric acid traditionally used is needed. This study investigated the efficiency of slurry bio-acidification treatment by adding different types and amounts of fermentable substrates to initiate and sustain the fermentation process. The carbon pools in the slurry were quantified to ...

Abstract:
... This study measured the level of technical efficiency among smallholder ginger growers and examined the determinants of inefficiency by employing the stochastic frontier production function. The paper used a simple random sampling technique to interview 100 ginger farmers in Ilam, a leading ginger-producing district in Nepal, with the help of a pretested interview schedule. The STATA.13 software w ...

The soil based potting mix (media) of four altered proportion of farmyard manure (FYM) and three different pot volumes were considered for quality seedlings production of tomato and chili in cylindrical shaped paper pots made of bio-degradable newspaper material (density 50 g m⁻²). The experimental factors include three paper pot sizes of 50 cm³ (V1), 70 cm³ (V2), and 90 cm³ (V3) volume and four p ...

Abstract:
... Nutrient pollution is a widespread problem in rivers in China. Managing nutrient pollution requires better knowledge of in-stream processes governing the surface water quality. As current nutrient models for China mainly focus on river export of nutrients to seas, in-stream surface water quality and their contributing sources and processes are, therefore not well understood. This requires accounti ...

Abstract:
... Biomass produced from agriculture at present provides most energy services in developing nations. In India, enormous quantities of biomass are produced for conversion into valuable energy. Bioenergy production from agricultural leftovers, animal manure, and municipal waste has the potential to meet of the rising need sustainable energy. It is a practical and sustainable option since the energy pro ...

... India is the world's ninth-largest grape-producing country. Maharashtra is a major producer of grapes and raisins, with the Sangli district accounting for a large portion of the total, hence becoming the area of focus of this research. Sangli becomes an important location for grape production. The objective of this research is to conduct a thorough, organized, and comprehensive energy analysis of ...

... Within the Southern Ocean, the greatest warming is occurring on the Antarctic Peninsula (AP) where clear cryospheric and biological consequences are being observed. Antarctic coastal systems harbour a high diversity of marine and terrestrial ecosystems heavily influenced by Antarctic seaweeds (benthonic macroalgae) and bird colonies (mainly penguins). Primary sea spray aerosols (SSA) formed by the ...

... Day-fresh Great Cormorant pellets were collected at a huge single winter roost at Kreupel island in Lake IJsselmeer, The Netherlands. The roost is situated on a sandy island, 3 m above the water level and is regularly used by 1000–8000+ Cormorants. By examining pellets and thus reconstructing the previous day's meal of Cormorants gathering at the roost, we explored spatio-temporal differences in t ...

Abstract:
... Renewable natural gas (RNG) sources are being considered in future energy strategy discussions as potential replacements for fossil natural gas (FNG). While today’s supply of RNG resources is insufficient to meet U.S. demands, there is significant interest in its viability to supplement and decarbonize the natural gas supply. However, the studies compare the life cycle global warming potential (GW ...

Abstract:
... Veterinary pharmaceuticals (VPs) are emitted into the environment and transfer to groundwater and surface water is diffuse and complex, whereas actual information on the fate is frequently limited. For 17 VPs of potential concern in the Netherlands, we assessed sources and emission due to animal slurry applications to soil. Hence, we examined the use of VPs in four livestock sectors in the Netherl ...
