Project - Bioenergy Farm 2 Agricultural bioenergy from liquid manure and residues
Project period: 2013-2016 ‘BioEnergy Farm 2’ supports farmers with the planning and construction of agricultural biogas plants. At the forefront is the recycling of the farms’ own residues, primarily liquid and solid manure. An online tool gives interested farmers the opportunity to have an initial estimation of the economic feasibility of the biogas plant. If the farmers show ...

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. ...

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 ...

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 ...

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 ...

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 ...
