The emission of greenhouse gases (GHG) during feedlot manure composting reduces the agronomic value of the final compost and increases the greenhouse effect. A study was conducted to determine whether GHG emissions are affected by composting method. Feedlot cattle manure was composted with two aeration methods--passive (no turning) and active (turned six times). Carbon lost in the forms of CO2 ...
Manure or compost from beef cattle feedlots can be excellent sources of nutrients and organic matter when added to soils. This study was conducted to determine the effect of a single application of manure and compost on runoff and erosion under no-till and tillage conditions. Tillage consisted of a single disking operation up and down the slope on a Sharpsburg soil which was cropped to grain so...
fate) reduced WEP concentrations in the litter relative to untreated chicken litter. Similarly, when alum-treated Water-extractable P (WEP) in manure is increasingly used as an and untreated litters were broadcast onto pastures, difenvironmental indicator as it is correlated with P in runoff from soils recently amended with manure. Little information exists on WEP ferences in dissolved P concen...
The objectives of this study were to estimate the prevalence of Mycobacterium avium subsp. paratuberculosis (MAP) among deer and rabbits surrounding infected and noninfected Minnesota dairy farms using fecal culture, and to describe the frequency that farm management practices were used that could potentially lead to transmission of infection between these species. Fecal samples from cows and t...
An integrated farming system is one of the alternatives for climatic change mitigation. This paper reports the application of corn-cattle based integrated farming system in Agrotechno Park Center of Palembang, and discusses its impact on CO2 fixation and the reduction of methane emissions. The study was based on the data of the first 6 yr from 2003 until 2009. The CO2 fixed in the soil and plan...
This study was carried out in the Teaching and Research Farm of Delta State University, Asaba Campus from March 2008 to December 2009 to evaluate the effects of previously applied amendments on maize grain weight and some soil properties. The experiment was carried out in a Randomized Complete Block Design (RCBD) replicated three times in a factorial layout. Four different rates of poultry drop...
Two field experiments were carried out during the summer seasons of 2001 and 2002 at the Experimental Station Farm of the Faculty of Agriculture, Alexandria University, at Abeis, to study the effects of four treatments of organic manure (unmanured, chicken, compost and cattle) and three biofertilizer treatments (uninoculated, Halex 2 and Nitrobein) on vegetative growth, yield potential and chem...
Cattle manure is frequently used as an inoculum for the start-up of agricultural biogas plants or as a co-substrate in the anaerobic digestion of lignocellulosic feedstock. Ruminal microbiota are considered to be effective plant fiber degraders, but the microbes contained in manure do not necessarily reflect the rumen microbiome. The aim of this study was to compare the microbial community comp...
Human campylobacteriosis is a common zoonosis with a significant burden in many countries. Its prevention is difficult because humans can be exposed to Campylobacter through various exposures: foodborne, waterborne or by contact with animals. This study aimed at attributing campylobacteriosis to sources at the point of exposure. It combined comparative exposure assessment and microbial subtype ...
background & aim: rosemary (rosmarinus officinalis l.) is an evergreen and aromatic plant that is used in pharmaceutical and cosmetic industries-health. little research has been reported on the greenhouse production of this plant. this paper presents the effects of municipal solid waste compost (mswc) and cattle manure on rosemary growth in pots at greenhouse. martial & methods: municip...
