  • Removal and recovery of ammonia from chicken manure

    The feasibility of the conversion of organic nitrogen available in raw chicken manure (CM) into ammonia via hydrolysis and the removal of ammonia from anaerobically digested manure were evaluated in this study. Firstly, the hydrolysis experiments were performed and the effects of temperature, total solids (TS) content and retention time were investigated. The results showed that 90% of the ...

  • Burn it no more!

    The other day I came across an old news article from 2008 about a Dutch energy plant that burns 485,000 tons of poultry litter each year, converting it into renewable electricity. Wow, I thought. That is an old-fashioned way of getting rid of poultry litter – they must be releasing some 14,550 tons nitrogen gas into the atmosphere. All this to produce 270,000 MWh of electricity, 890,000 MWh ...

  • Chicken Manure Management, Recycling, and Composting

    Chicken Manure Fertilizer Manufacturing Process If you have chickens, you will have manure. Fortunately, chicken manure is among the most prized of manures. Fresh chicken manure is considered a “hot” manure, which is unsuitable for immediate use. Chicken manure needs to be composted and aged at least two to three months before you add it to your garden. If you don’t wait ...

  • Animal Manure or Sludge Organic Fertilizer Production

    Introduction of Animal Manure or Sludge Organic Fertilizer Production Line Organic fertilizer production line is designed for producing organic fertilizer from animal manure or sludge, without any chemical ingredients. As chickens, pigs have a poor digestion, can only consume 25% of the nutrients, so other 75% of feed nutrients with feces discharge can be produced to the dry ...

  • Unlocking the potential of poultry manure

    The poultry industry is one of the largest and fastest-growing agro-based industries in the world. At the same time, the growth brings along a number of environmental problems. One of the major environmental problems is the accumulation of large amounts of wastes, e.g. manure. In order to mitigate these problems new economically sustainable technologies are needed. Manure has often been ...

  • Rainfall-induced release of microbes from manure: model development, parameter estimation, and uncertainty evaluation on small plots

    A series of simulated rainfall-runoff experiments with applications of different manure types (cattle solid pats, poultry dry litter, swine slurry) was conducted across four seasons on a field containing 36 plots (0.75 × 2 m each), resulting in 144 rainfall-runoff events. Simulating time-varying release of Escherichia coli, enterococci, and fecal coliforms from manures applied at typical ...

  • Poul-AR Valorization of poultry manure - Fertilizer and energy from poultry manure

    Application In contrast with generic manure types, poultry manure is very rich in nutrients as nitrogen (N) & phosphorus (P), but also in organic material. Both the form and the N/P ratio in which the nutrients are present make the manure less suitable for direct application as natural fertilizer. It leads to the release of large and undesired amounts of volatile ammonia into the ...

  • A `classic` for agriculture - case study

    A 500 kW-Biogas plant (typical to its kind in every regard) is located in Gehlenberg. There, 500 kW were legally defined as the permissible maximum limit value for agricultural operations. In Gehlenberg, the competent consulting services provided by bwe attracted particularly positive attention. After all, the plant (operational since 2006) is impressive in its high degree of overall efficacy and ...

  • Composting of washed Ulva reticulata seaweed: process parameter variations and compost quality

    Co–composting process of unwashed (Run A) and washed (Run B) seaweed Ulva reticulata with bagasse and broiler litter was studied. Peak temperatures of 48.9°C and 55.2°C were recorded for Runs A and B, respectively. For Run A, the starting wet bulk density was 43.31 kgm–3 and increased by 5.2 times on day 23. Net biodegradable Volatile Solid (VS) reductions were 2.19 and 11.44% ...

  • Global Grain Stocks Drop Dangerously Low as 2012 Consumption Exceeded Production

    The world produced 2,241 million tons of grain in 2012, down 75 million tons or 3 percent from the 2011 record harvest. The drop was largely because of droughts that devastated several major crops—namely corn in the United States (the world’s largest crop) and wheat in Russia, Kazakhstan, Ukraine, and Australia. Each of these countries also is an important exporter. Global grain ...

  • The effect of poultry manure application rate and AlCl3 treatment on bacterial fecal indicators in runoff

    Increasing costs associated with inorganic fertilizer have led to widespread use of broiler litter. Proper land application, typically limiting nutrient loss, is essential to protect surface water. This study was designed to evaluate litter-borne microbial runoff (heterotrophic plate count bacteria, staphylococci, Escherichia coli, enterococci, and Clostridium perfringens) ...

  • Earthworms helping economy, improving ecology and protecting health

    Earthworms can treat organic garbage, livestock manure and poultry droppings and turn them into premium organic fertilisers, because humus only exists in earthworm feces and castings, compared with other fertilisers. Earthworms can also supply quality animal protein as feed, and offer the best raw materials for the biochemical and pharmaceutical industries. Vermiculture should be put into a whole ...

  • Free and Conjugated Estrogen Exports in Surface-Runoff from Poultry Litter–Amended Soil

    Land application of animal manures such as poultry litter is a common practice, especially in states with surplus manure. Past studies have shown that animal manure may contain estrogens, which are classified as endocrine-disrupting chemicals and may pose a threat to aquatic and wildlife species. We evaluated the concentrations of estrogens in surface runoff from experimental plots (5 × 12 ...

  • Equivalency of broiler litter to ammonium nitrate as a cotton fertilizer in an upland soil

    Estimates of litter value based on crop yield equivalency to inorganic fertilization may reflect the actual value of litter more accurately than estimates based on its N, P, and K content. The primary objective of this research was to identify a rate of broiler litter that results in cotton lint yield equivalent to inorganic N fertilization and to estimate litter value based on this yield ...

  • Phosphorus runoff from wastewater treatment biosolids and poultry litter applied to agricultural soils

    Received for publication March 19, 2009. Differences in the properties of organic phosphorus (P) sources, particularly those that undergo treatment to reduce soluble P, can affect soil P solubility and P transport in surface runoff. This 2-yr field study investigated soil P solubility and runoff P losses from two agricultural soils in the Mid-Atlantic region after land application of biosolids ...

  • Improving soil nutrition with poultry litter application in low-input forage systems

    Despite high volumes of manure production in the Shenandoah Valley of Virginia, there are still areas of forage production that are nutrient deficient because manures have traditionally been applied to higher-value row crops. This study was conducted to compare the effects of poultry litter and inorganic fertilizers on soil fertility and forage production. Two sites had the same treatments ...

  • Management of waste organic matters and residential used water for culture and biomass production of red worm (Tubifex tubifex)

    The efficacy of red worm (Tubifex tubifex) for converting organic wastes like pig dung, poultry excreta and dairy sludge into worm biomass production was investigated. For this purpose, three experiments each for pig dung, poultry excreta and dairy sludge were conducted in cement trenches for 90 days duration. The poultry excreta produced maximum biomass (126.53 ± 2.16 g), followed by the ...

  • Effects of composting on removal of nitrogen, phosphorus, and potassium

    A six month study evaluated composting affects on nitrogen (N), phosphorus (P), and potassium (K) leaching from hardwood and furniture sawdust amended with 20% and 30% chicken litter. Toxicity Characteristic Leaching Procedure (TCLP) was obtained from substrates. Moisture was provided through precipitation, and the substrate was aerated once or twice per week, depending on the amount of rainfall. ...
