Odor from anaerobic digestion of swine slurry: influence of pH, temperature and organic loading
(2014)
Farm slurry management from storage and/or treatment is the main source of odors from swine production, which are determined by factors such as operational variations (organic loading), cleaning of facilities and animal ...
Copper and zinc forms in soil fertilized with pig slurry in the bean crop
(Univ Federal Campina Grande, 2016-09-01)
The application of pig slurry may have different influence on copper (Cu) and zinc (Zn) dynamics in the soil compared with mineral fertilization. The aim of this research was to determine the different forms of Cu and Zn ...
SWINE WASTEWATER: IMPACTS ON SOIL, PLANT, AND LEACHATE
(Soc Brasil Engenharia Agricola, 2017-09-01)
The use of animal-origin residues as a nutrient source without prior and proper investigations on their positive and negative impacts can affect the quality of agricultural soils and the environment into which they are ...
Relationships among Physicochemical, Microbiological, and Parasitological Parameters, Ecotoxicity, and Biochemical Methane Potential of Pig Slurry
(MDPI, 2023-02-09)
Background: Pig slurry can negatively impact on the environmental, animal, and human health. Knowing the relationship between the organic and inorganic loads, pathogens, and toxicity allows identifying the main parameters ...
Soil carbon and nitrogen mineralization caused by pig slurry application under different soil tillage systems.
(Pesquisa Agropecuária Brasileira, Brasília, v.45, n.5, p.515-521, maio. 2010, 2014)
Toxicity identification evaluation of anaerobically treated swine slurry: A comparison between Daphnia magna and Raphanus sativus
(2014)
Anaerobic digestion does not efficiently reduce ionic compounds present in swine slurry, which could present a potential risk to aquatic ecosystems (surface runoff) and terrestrial ambient (irrigation). The objective of ...
Distribution and availability of copper and zinc in a constructed wetland fed with treated swine slurry from an anaerobic lagoon
(2014)
The distribution and availability of copper and zinc in a constructed wetland fed with treated swine slurry from an anaerobic lagoon was studied. The methodology regarded the seasonal distribution of metals inside Schoenoplectus ...
Nitrogen and phosphorus distribution in a constructed wetland fed with treated swine slurry from an anaerobic lagoon
(2015)
Nitrogen and phosphorus distribution in a constructed wetland fed with treated swine slurry from an anaerobic lagoon were studied. The methodology considered a daily meteorological monitoring site. During 2011 to 2012, ...
