In order to identify the phosphorus species and concentration in animal manure, we comparatively characterized phosphorus in dairy manure, swine manure, and broiler litter, using a sequential procedure, a simplified two-step procedure (NaHCO3/NaOH+EDTA), and a solution Phosphorus-31 Nuclear Magnetic Resonance (31P-NMR) spectroscopy procedure. In the sequential procedure, deionized water extract...

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...

Acknowledgements These results are compiled by Agro Business Park based on inputs from the whole project group. Without these dedicated inputs and the great spirit of cooperation between the research institutions involved and across borders and scientific traditions and disciplines, the result would have been much less coherent – and much less useful. It is our hope that the results presented h...

Animal manure is commonly used as fertilizer for agricultural crops worldwide, even though it is believed to contribute to the spread of antibiotic resistance from animal intestines to the soil environment. However, it is unclear whether and how there is any impact of manure fertilization on populations and community structure of antibiotic-resistant endophytic bacteria (AREB) in plant tissues....

production is hard to achieve by increasing cropping area due to limited water resources. so, increased yield per unit area may be the solution to increase production. investigating productivity of production factors is very important in this context. the objective of this study is to measure the productivity of production factors in sugar beet production in fars province. the data needed for t...

Mechanical separation of liquid animal manure can be an effective technique for production of a liquid and a nutrient-rich solid fraction. The efficiency of separators depends on the physical and chemical composition of the animal manure. Therefore, the particle size composition was measured for different types of manure before treatment with a decanting centrifuge and a screw press. Storage of...

Stable flies are blood-feeding insects with a great negative impact on animals world wide. Larvae develop primarily in animal manure and bacteria are essential for larval development; however, the principle of this dependence is not understood. We hypothesized that as the microbial community of animal manure changes over time, it plays an important role in stable fly fitness. Two-choice bioassa...
