The economic value of cattle manure
2015The aim of this paper is to determine economic value of farmyard manure. Manure contains the nutrients that are necessary for plants growing, and organic matter especially important for maintaining fertility of the soil. It is usually underestimated and not often used when compared with mineral fertilizer. Application of the farmyard manure affects the

Thermal properties of beef cattle manure
Agricultural Wastes, 1983Abstract The thermal conductivity of beef cattle manure was measured by a transient state method, while its specific heat was measured by a classical method of mixtures. The specific heat of beef cattle manure was found to decrease as Total Solids concentration (TS) increased, ranging from 4·13 kJkg−1 °C−1 at 1·42% TS to 1·400 kJkg−1 °C−1 at 99·4% TS.

Enhancing anaerobic hydrolysis of cattle manure in leachbed reactors
Bioresource Technology, 2009In this study, it is hypothesized that anaerobic hydrolysis of organic solid wastes (OSWs) in leachbed reactors can be enhanced by two approaches: (1) by increasing the porosity of the leachbed; and (2) by seeding the bed with brown-rot fungi or anaerobically digested residues.

Pipeline vs. truck transport of beef cattle manure
Biomass and Bioenergy, 2005Anaerobic digestion of manure can be conducted at a wide range of capacities. As capacity increases, economies of scale in capital equipment are realized but transportation costs increase as manure must be carried longer distances to the plant site. In this study we evaluate the cost of pipelining manure from beef cattle confined feeding operations,

cattle manure microbial networks
To improve cattle manure composting in cold regions, this study evaluated the effects of initial C/N ratio optimization under microbial inoculation on composting performance, maturity indicators, final microbial communities, and potential microbial association networks. Methods: Four treatments were established: CK, natural composting at the native C/Nopenaire +1 more source
Manure and Wastewater Management for Cattle Feedlots
2000The United States has 102 million cattle and calves (average for 1995-1997), and in 1996, a monthly average of 9.2 ± 1.1 million animals (head, hd) were in beef cattle feedlots being finished for slaughter (TCFA 1997). These finishing cattle generally range in liveweight from 272 to 544 kg, averaging approximately 408 kg/hd.

Influence of liquid cattle manure on reduction processes in soil
Biology and Fertility of Soils, 1993Reduction processes in cultivated soil during the decomposition of liquid cattle manure were studied in laboratory experiments. Anoxic slurries of soil and manure in different proportions or alone were followed over 5 weeks. Upon NO inf3 sup- depletion, ferrous Fe appeared in solution in soil-manure ...

The Effect of Cattle Manure to Styrofoam Concrete
This study aims to produce a styrofoam concrete product with the additives of cattle manure, addressing the issue of pathogen contamination in agricultural fields and water bodies. The product will be evaluated by the stability, durability, and insulation properties based on ASTM C 39 Compression Test, ASTM E-119 Flammability Test, and ASTM C 140 WaterGabriel, Ma.
