Methane productivity of manure, straw and solid fractions of manure
Biomass and Bioenergy, 2004Abstract The methane productivity of manure in terms of volatile solids (VS), volume and livestock production was determined. The theoretical methane productivity is higher in pig (516 l kg −1 VS ) and sow (530 l kg −1 VS ) manure than in dairy cattle manure (469 l kg −1 VS ) , while the ...

Trace Elements in Feed, Manure, and Manured Soils
Journal of Environmental Quality, 2012Modern animal feeds often include nutritional mineral supplements, especially elements such as Cu, P, Se, and Zn. Other sources of trace elements also occur in livestock systems, such as pharmaceutical use of As and Zn to control gut flora, Bi in dairy for mastitis control, and Cu as hoof dips.

Horse manure is a poor feedstock whose energetic content is comparable to that of herbaceous biomass. However, it can be effectively burnt provided that it is previously desiccated, being its moisture content very high (60% wb).This work reports an experimental investigation to identify optimal conditions for horse manure drying in a bench-scale direct

Manuring of grassland. III.—Manuring and Utilization
Journal of the Science of Food and Agriculture, 1953AbstractThe role of grassland in increasing the nation's food supplies is discussed. Fertilizer dressings for various swards are recommended, with the proviso that plans for efficient utilization must precede any step to grow more grass. Figures from cost accounts taken on some 60‐70 dairy and mixed farms are quoted.

Investigation of composition of biomass is an important pre-requisite for determining its suitability for various downstream applications. In recent times, food waste has emerged as a valuable biomass feedstock which could be valorized for production of fuels, chemicals and materials.

Green leaf manuring and green manuring
Madras Agricultural Journal, 1950The terms "Green Leaf Manuring" and "Green Manuring" convey technically different meanings, though the ultimate object is the same in both cases. The practice of lopping green leaves from trees like Pungam, Neem etc., and applying them to paddy fields is called "Green Leaf Manuring." When crops like Pillipesra, Daincha, Sunnhemp, Indigo and Wild Indigo

Environmental Letters, 1972
Abstract Fresh, partially decomposed, and aged manure samples were examined for the presence of nitrates, nitrites and secondary amines, precursors of nitrosamines. Nitrate, nitrite and total amine nitrogen were found in amounts ranging from 53.2 to 202.3 ppm; 37.1 to 51.9 ppm; and 12.7 to 28.4 ppm, respectively.

Kinetics of Methane Production from Swine Manure and Buffalo Manure
Applied Biochemistry and Biotechnology, 2015The degradation kinetics of swine and buffalo manure for methane production was investigated. Six kinetic models were employed to describe the corresponding experimental data. These models were evaluated by two statistical measurements, which were root mean square prediction error (RMSPE) and Akaike's information criterion (AIC).

Animal Manures as feedstuffs: Poultry manure feeding trials
Agricultural Wastes, 1983Abstract The utilisation of dried poultry manure as a feedstuff was critically evaluated based upon feeding trial results reported in the literature. The assessment indicated that this material can have value as a feedstuff. The maximum and optimum levels of incorporating dried poultry manure into laying hen and ruminant rations, on the basis of ...
