Formation and emissions of ammonia and greenhouse gases from stored and composted solid animal manure
Beside other branches of industry, agriculture is an important source of methane (CH4) and nitrous oxide (N2O) emissions and the most important source of ammonia (NH3). In spite of several investigations concerning ammonia and greenhouse gas emissions during storage and composting of liquid and solid animal manure, the real extent of these emissions is still unknown. This is mainly because of the ...

Anaerobic monodigestion of poultry manure: determination of operational parameters for CSTR
In this work the anaerobic monodigestion for the treatment of turkey manure was evaluated, without its codigestion with another substrate. The effect of the organic loading rate (OLR) and the substrate concentration (high total solids (TS) concentration) or product concentration (high volatile fatty acids (VFA) and/or ammonia (NH3-N) concentrations) was studied. The results show that for a ...

Composting dairy solids with the ac composter
In October, ECS began conducting trials at California State University Fresno to explore using the new patent pending AC Composter system to manage dairy manure solids and comply with air-quality standards. A two-zone portable pilot system was delivered by ECS and installed at the CSUF's research dairy. This research is being conducted with funds from a USDA Small Business Innovative Research ...

Nitrogen immobilization and mineralization kinetics of cattle, hog, and Turkey manure applied to soil
Nitrogen mineralization and immobilization following manure application are critical processes influencing plant N supply and offsite N losses. We conducted laboratory experiments to examine the influence of these two processes in addition to N oxide gas production on N availability for 180 d following manure addition. A Tara loam (fine-silty, mixed, superactive, frigid Aquic Hapludoll) and a ...

Quality of compost: the experience of veneto region
The Regional Administration of Veneto Region (Italy) established in 1991 the rules for authorisation of composting plants for treatment of pre-selected organic wastes, including urban sludges, organic fraction of municipal solid wastes and animal manure. Also chemical composition of compost were regulated (Table 1). Some composting plants started working in 1994; at the moment seven farms are ...

Basic process of manure fertilizer production from farm manure
The composting method of organic manure production is a process of mineral, humic and harmless degradation of organic matter in solid manure by microorganism under the condition of artificial control of water, carbon nitrogen ratio and ventilation. Composting is mainly divided into aerobic composting and anaerobic composting, which is mainly aerobic composting at present. Composting manure ...

Agricultural Manure Drying Machine for Cows
Manure drying machines are utilized in agricultural settings to remove moisture from wet manure. The drying process breaks down manure, kills bacteria and creates pathogen-free bedding. The drying process also cuts down on storing and disposing of bulk manure and the costs associated with both activities. Dried Manure Solids (DMS) can be used as bedding for the dairy industry. A lactating ...

Solids Reduction Dramatically Improves Manure Handling In Western Pennsylvania with MICROBE-LIFT® - Farm Waste Management
Farmer Boy Agricultural Supply Co., ViewFamily Farms (CVFF),Western Pennsylvania This was a CVFF contracted sow farm constructed with shallow manure pits in two barns, each followed by million gallon collection pits. This farm was experiencing problems with their large pull-plug operations. The shallow pits in the barns were blocked with sludge causing additional problems in their two million ...

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 ...

Dairy farm Oklahoma, USA
Type of Wastewater System: Facility to Sediment Basin for Solids collection, Sediment Basin to Lagoon for Water collection Expectations: This facility was in need of solid removal from sediment basin as it was to a point of water flow restriction and solid capacity in the sediment basin. The expectation was to liquefy the solids in the sediment basins using microbial augmentation, and to not use ...

A cost-effective method for controlling compost air emissions
In October 2007, ECS began conducting trials at California State University Fresno (CSUF) to explore using the new patent pending AC Composter (ACC) covered aerated static pile system to manage dairy manure solids and comply with airquality standards. A two-zone portable pilot system was delivered by ECS and installed at the CSUF research dairy. This research is being conducted under a Phase I ...

Organic amendment history and crop rotation effects on soil Nitrogen mineralization potential and soil Nitrogen supply in a potato cropping system
Crop management practices influence readily and potentially available N in soil. In this study, we evaluated the effects of organic amendment history and crop rotation on potentially mineralizable N (N0), mineralizable N pools, and field estimates of soil N supply in potato (Solanum tuberosum L.) production, and evaluated a suite of N availability measures to detect changes in these parameters. ...

Cover crop and liquid manure effects on soil quality indicators in a corn silage system
Due to a lack of surface residue and organic matter inputs, continuous corn (Zea mays L.) silage production is one of the most demanding cropping systems imposed on our soil resources. In this study, our objective was to determine if using cover/companion crops and/or applying low-solids liquid dairy manure could improve physical, chemical, and biological soil properties and overall soil quality. ...

Efficient Manure Separation: Screw Press vs. Slope Screen Separator
In the realm of agricultural and livestock farming, the responsible management of manure is of paramount importance. Manure, a valuable resource rich in organic matter and nutrients, can be a double-edged sword for farmers. On one hand, it serves as a potent natural fertilizer; on the other, its mismanagement can lead to environmental issues. To address this challenge, farmers have turned to ...

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 ...
