A field experiments were carried out at Shambat, Sudan (Latitude 15 40 ́N and Longitude 32 o o 32 ́E) in three consecutive seasons (2000/03) to investigate the effect of Bradyrhizobium inoculation and chicken manure or sulphur fertilization on minerals composition of soybean (Glycine max L.). The results obtained showed that inoculation, chicken manure, sulphur and their interactions significantl...

A plot scale study was conducted to determine bacterial transport in runoff from cropland treated with poultry litter and dairy manure applied at phosphorus (P) agronomic rates. Treatments included surface application of dairy manure, surface application of poultry litter, incorporation of dairy manure and control. A rainfall simulator was used to induce runoff 1 and 2 days after manure applica...

Livestock are known contributors to stream pollution. Numbers of fecal streptococci and Escherichia coli in manure naturally deposited by livestock in the field are needed for activities related to bacterial source tracking and determining maximum daily bacterial loading of streams. We measured populations of fecal streptococci and E. coli in fresh and dry manure from cattle (Bos taurus L.), ho...

Over 9 million dairy cows generate an estimated 226 billion kg of wet manure annually in the US. The purpose of this study was to demonstrate the viability of a novel two-stage anaerobic digestion (AD) process for producing methane-rich biogas on pre-fermented dairy manure. In summary, it was observed that AD of thickened pre-fermented manure can generate comparable biogas quantities to AD usin...

The overapplication of mineral nitrogen (N) fertilizer has become a scientific problem to be solved in the North China Plain; meanwhile, most organic manure cannot recycled into soil. To make full use and decrease applied rate N fertilizer, four-year fertilization experiment was carried out assess effects substituting with on soil carbon (SOC), labile (LOC), stable (UOC), microbial biomass (MBC...

Manure or compost application based on N needs of corn (Lea mays L.) may result in soil accumulation of P, other ions, and salt because the manure or compost N/P ratio is usually smaller than the corn N/P uptake ratio. This study was conducted from 1992 to 1996 to evaluate effects of Pand N-based manure and compost application on corn yield, N and P uptake, soil P level, and weed biomass. Compo...

With the aim of the improvement water retention in dry land condition by green manure application, this study was carried out with or without rye green manure along with 4 nitrogen fertilization rate in green manure-wheat rotation system between 2001 – 2007 years. Results showed that the green manure application effects were significant on the soil aggregate stability, soil bulk density and ava...

A study of new pig manure treatment and filtration process was carried out. The advantage of the worked out technology is the method of incorporation of crystalline phase into solid organic part of manure. The obtained new solid phase of manure contains about 50% of crystalline phase forming a filtration aid that enables high effectiveness of manure filtration. The filtration rate of manure sep...

Two pilot composting experiments were conducted to investigate the effect of low initial C/N ratio on the composting of swine manure with rice straw by measuring physical and chemical parameters. The results showed that the thermophilic duration of bin 1 and bin 2 was long enough to satisfy the sanitary standard, and swine manure could reach maturity. Bin 1 containing larger amount of swine man...

No information regarding the management of manure from beef cattle feedlots is available for Brazil. To fill this knowledge gap, a survey of 73 feedlots was conducted in 7 Brazilian states. In this survey, questions were asked regarding animal characteristics, their diets, and manure handling management from generation to disposal. These feedlots finished 831,450 animals in 2010. The predominan...
