Bacteria thrive in a slurry with a pH around 7.0. Consequently, if the incoming slurry has a pH in this range, digestion should proceed smoothly. Under normal conditions, the digestion process balances excess acidity or alkalinity on its own. Carbon is the major chemical element in manure, and the bacteria digest the carbon with the release of biogas.
Effect of cow slurry amendment on atrazine dissipation and Jun 15, 2010 · This effect may be caused either by the sorption of the pesticide to organic matter or more rapid degradation in slurry-amended soils. The objectives of this study were to evaluate the effects of cow slurry on atrazine dissipation, the formation of atrazine metabolites and the modification of bacterial community in Andisol.
Jan 26, 2017 · Unreasonable use of chemical fertilizer (CF) on agricultural soil leads to massive losses of soil organic carbon (SOC) and total nitrogen (TN) in tropical and subtropical areas, where soil conditions are unfavorable for aggregate formation. This study evaluated the effects of combined application of biogas slurry (BS) plus CF on soil aggregation and aggregateassociated C/N concentration and

Effects of Pig Slurry Application on Soils and Soil Humic With respect to the control soil, the pig slurry amended soils had greater pH and electrical conductivity, slightly larger total N content, and smaller values of C/N ratio. A decrease of total organic C was observed only in soils amended for 2 and 3 years at the higher slurry rate.
This paper addresses the effects of AD on digestate composi-tion and their fertilizing effects, as well as the available digestate treatment procedures. It will give an overview of the state of the art and further research needs. Not included is potassium, as it does not become part of structural
Environmental Consequences of Future Biogas Technologies This consequential life cycle assessment study highlights the key environmental aspects of producing biogas from separated pig and cow slurry, a relatively new but probable scenario for future biogas production, as it avoids the reliance on constrained carbon cosubstrates. Three scenarios involving different slurry separation technologies have been assessed and compared to a business-as-usual
Parametric effects on the erosioncorrosion rate and Consequence influence corrosion processes during the maintenance low carbon steel with animal slurry atmosphere can be atmosphere corrosion effect, too (Naz et al., 2017;Uhlig and Revie, 1985
Abstract. Animal slurry contains plant nutrients that are essential for crop production. However, intensive livestock production may lead to a surplus of plant nutrients on farms and, as a consequence, discharge or emission to the environment. In order to ensure that the slurry applied to fields matches the nutrient requirements of the crops, techniques have been developed to reduce the nutrient content of slurry Short-Term Effects of Biogas Digestates and Pig Slurry Application of four different biogas digestates and pig slurry to soil resulted in both stimulatory and inhibitory short-term effects on microbial functions. Soil respiration displayed varying patterns, reflecting the differences in both the quantity and quality of the organic carbon in the residues, but no negative effects were observed.
