Growing concern about water quality issues, along with a series of fish kills in 1997, prompted Maryland, Delaware, and Virginia to adopt regulations to reduce nutrient pollution from agricultural nonpoint sources. All three states required farmers to follow a state-certified nutrient management plan that would "optimize crop yields and minimize environmental losses," although the policy-making...

Manure management in livestock makes a significant contribution towards greenhouse gas emissions in the Agriculture; Forestry and Other Land Use category in South Africa. Methane and nitrous oxide emissions are prevalent in contrasting manure management systems; promoting anaerobic and aerobic conditions respectively. In this paper; both Tier 1 and modified Tier 2 approaches of the IPCC guideli...

Salt-affected soil reclamation provides opportunities for crop production and carbon sequestration. In arid regions such as Pakistan, limited studies have been reported involving under wheat–maize rotation, but no study has predictions on long-term sequestration in reclaimed soils the treatments used this study. Thus, a field-scale fallow period experiment was conducted rotation salt-affected P...

A pot experiment was carried out in 2019 the net house of Department Soil, Water and Environment, University Dhaka, to evaluate growth yield Jute plants (Corchorus capsularies L.) by applying different types organic manures. Eight manures viz. ACI, BGF-1, Mazim, Vermicompost, Shufola, GTS, Green Poultry were collected from local market. The set up following a completely randomized design (CRD) ...

lack of adequate organic matter (om) in the agricultural soils of iran is responsible for the poor physical condition of these soils. thus, increasing soil om is very important. on the other hand, the eutrophication of surface water caused by continuous use of phosphorus (p) fertilizer has created an interest in the combined use of organic wastes and p fertilizer. hence, the present study was u...

Campylobacteriosis is a zoonotic disease which has a worldwide public health impact. The disease is endemic in Egypt; however, the epidemiology in animals and humans has not been fully characterized. The objective of this study was to compare the risk of Campylobacter faecal carriage in children exposed to Campylobacter-infected vs. non-infected backyard poultry and to identify risk factors for...

A field experiment was conducted on deep vertisols of Bhopal, India to evaluate the manural potential of three organic manures: farmyard manure (FYM), poultry manure (PM), phosphocompost (PC) vis-a-vis 0%, 75% and 100% recommended dose of fertilizer-NPK and to find out the most productive cropping system at various combinations of organic manures and chemical fertilizers. The seed yield of inte...

The pollution of antibiotic resistance genes (ARGs) in livestock farms is a problem which need to be paid more attention to, due to the severe resistance dissemination and the further human health risk. In this study, all the relevant exposure matrices (manure, soil and water) of sixteen animal farms in Southeastern China were sampled to determine twenty-two ARGs conferring resistance to five m...
