Approaches for adding value to anaerobically digested dairy fiber
(2017)
One of the consequences of the increase of large dairy concentrated feeding operations (CAFOs) is the abundance of dairy manure that needs to be disposed of or used in some way. CAFOs can become bio-refineries, harnessing ...
Charcoal from anaerobically digested dairy fiber for removal of hydrogen sulfide within biogas
(2018)
Anaerobically digested fibrous solid (AD fiber) is an abundant material that offers potential to produce value-added products such as biochar. The objective of this paper is to better understand how thermochemical processing ...
Hot water extraction of anaerobic digested dairy fiber for wood plastic composite
(2016)
Dairy farmers worldwide are facing the difficulty of managing or disposing of dairy manure. Anaerobic digestion (AD) is an option for treating dairy manure and producing biogas. A byproduct of AD is fiber, which is only ...
The Impact of Organic Biofertilizer Application in Dairy Cattle Manure on the Chemical Properties of the Soil and the Growth and Nutritional Status of Urochroa Grass
(Taylor & Francis Inc, 2018-01-01)
The management of nitrogen (N) fertilization in pasture has great importance for yield and maintenance of Brazilian livestock. The objective of this study was to evaluate soil chemical attributes, shoot dry weight yield ...
Anaerobic co-digestion of animal manure at different waste cooking oil concentrations
(Univ Federal Santa Maria, 2018-01-01)
This study aimed to obtain the best dose of waste cooking oil inclusion for the co-digestion of substrates prepared with dairy cattle and swine manure in order to maximize solids reductions and biogas yield. Analyses of ...
Feeding and fertilization practices and greenhouse gas emissions in specialized dairy farms of Dos Pinos in Costa Rica
(2016)
Emissions of methane (CH4) and nitrous oxide (N2O) based on the feeding systems of 104 dairy farms in Costa Rica were estimated using IPCC procedures. This study indicated that farmers’ decisions, which determine the feeding ...
Milk production of grazing cows in kikuyo (pennisetum clandestinum, ex chiov) fertilized with poultry manure
(2021)
Background. The use of organic fertilization on grasslands is an option on the biological, economic and environmental sense. Objective. In order to evaluate the poultry manure applied as a fertilizer in Kikuyo pastures ...
Production and characterization of H2S and PO4 3− carbonaceous adsorbents from anaerobic digested fibers
(2019)
Anaerobic digestion (AD) is an important technology to produce biogas from dairy manure. Although the AD of dairy manure results in the harnessing of the energy contained in manure, most of the nutrients (phosphorous and ...

(2021)
Background. The use of organic fertilization on grasslands is an option on the biological, economic and environmental sense. Objective. In order to evaluate the poultry manure applied as a fertilizer in Kikuyo pastures ...
Cultivo de adubos verdes forrageiros em solo previamente irrigado com efluente tratado de laticínio e cultivo em sucessão da alface
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Agroecologia e Desenvolvimento Rural - PPGADR-ArCâmpus Araras, 2016-11-24)
The aim of this study was to evaluate the potential for cultivation of forage green manure species in previously irrigated soil with treated dairy effluent, as a phytoremediation technique of sodium, and cultivation in ...
