Effect of Alum treatment on the concentration of total and Ureolytic microorganisms in poultry litter
Microbial mineralization of urea and uric acid in poultry litter results in the production of ammonia, which can lead to decreased poultry performance, malodorous emissions, and loss of poultry litter value as a fertilizer. Despite the fact that this is a microbial process, little is known about how the microbial populations, especially ammonia-producing (ureolytic) organisms in poultry litter, ...

Different ways to make use of your poultry litter
The poultry industry is one of the fastest growing industries in the world. The industry supplies us with an enormous amount of poultry meat, but also produce tons of waste materials in the process. What is poultry litter? Poultry litter is the mixture of bedding materials such as sawdust and wood shavings, feathers, spilled feed, and manure. In this mixture there are a number of nutrients that ...

A new method of poultry litter application to perennial pasture: Subsurface banding
Recently, incorporation of poultry litter by subsurface band application into pasture has been shown to reduce surface runoff transport of nutrients; however, data to evaluate the impact of this potential management strategy on forage production, forage nutrient concentrations, or the accumulation of soil nutrients after multiyear applications is limited. Therefore, two experiments, one in ...

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 ...

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 ...

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) while applying ...

Nitrogen mineralization in a pecan ( Carya illinoensis K. Koch)–cotton ( Gossypium hirsutum L.) alley cropping system in the southern United States
Information on temporal and spatial patterns of N mineralization is critical in designing tree-crop mixed systems that could maximize N uptake while minimizing N loss. We quantified N mineralization rates in a pecan (Carya illinoensis K. Koch)–cotton (Gossypium hirsutum L.) alley cropping system in northwestern Florida with (non-barrier) and without tree-crop belowground interactions (barrier ...

Starting of biobang - Germany - 30/09/2019
In date 09/30/2019 our technicians went to Ramnstein Miesenbach at the biogas plant ABO Kraft & Wärme company to BioBANG for the first time, recirculated on the primary digester of one of the two plant’s production lines. This plant produces 900 Nm3/h of biogas and is fed with about 90 t/day of products composed by cattle manure, horse manure, corn silage, triticale silage, grass ...

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 ...

Evaluation of Phosphorus source coefficients as predictors of runoff Phosphorus concentrations
Received for publication December 27, 2007. Many states have adopted a P site index (PSI) as a risk assessment tool to determine when P-based nutrient management is required for a given agricultural field. Some PSIs use a weighting factor, the phosphorus source coefficient (PSC), to account for differences in P solubility between organic P sources. Information relating to appropriate values of ...

The effects of bioadditive in the form of yeasts and zeolite on the composting process and odour emission
The objectives of this paper are to determine the effectiveness of bioadditive in the form of yeasts and zeolite in reducing odour and ammonia emissions during composting and to assess its effects on the process. Two series of experiments were conducted. The higher dosage treatments reached thermophilic temperatures sooner and the high temperatures stayed longer. The application of bioadditive at ...

The mineralization of nitrogen from compost in the tropics
The application of organic matter is very important in maintaining high and stable crop yields under tropical conditions. Most of tropical soils are characterised by low content of organic matter and low structure stability. Animal wastes contain many nutrients, including nitrogen, phosphorous, potassium and other minerals. In addition to supplying nutrients, the application of animal wastes also ...

Ammonia Reduction & Reduced Beetle Larvae with MICROBE-LIFT® Technology in Poultry Composting in Honduras - Farm Waste Management
Lazarus & Lazarus, a technology-based construction firm in Honduras, contacted a distributor of Ecological Laboratories to explore technology to improve their poultry litter processing. Ecological Laboratories’ technologists devised a test protocol using MICROBE-LIFT® technology conducted at an experimental poultry farm. This farm is utilized to evaluate new technology to optimize ...

Rainfall simulation in greenhouse microcosms to assess bacterial-associated runoff from land-applied poultry litter
Runoff water following a rain event is one possible source of environmental contamination after a manure application. This greenhouse study used a rainfall simulator to determine bacterial-associated runoff from troughs of common bermudagrass [Cynodon dactylon (L.) Pers.] that were treated with P-based, N-based, and N plus lime rates of poultry (Gallus gallus) litter, recommended inorganic ...

Dealing with Christmas poultry waste
With Christmas around the corner, farmers across the UK are extremely busy with the preparation of turkeys. Although we initially associate turkeys with Christmas, the preparation for this period begins months in advance. Turkey farmers must make sure they have the best breeds of turkey as consumers are more aware of the difference in quality. Customers are willing to pay significantly more for ...

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 ...

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 nitrogen, ...
