How much methane is released from the decomposition of cow manure?
In general the decomposition of manure does not lead to the formation of methane. Manure decomposing on the surface of soil is mostly an aerobic process. If the manure is buried in damp soil there is some chance for methane production. Some farms gather manure from feedlot operations or stalls and digest it in anaerobic digesters for methane fuel. Little or none escapes to the environment The majority of methane released by cattle results from the digestion of food in their bodies. It is released as flatulence

How does a biogas plant work?
"A centralized biogas plant assists surrounding farmers in their disposal of animal manure by digesting it in order to create a homogeneous fertilizer. In addition to the animal manure, the plants also use organic material from slaughterhouse, fishing industry tanneries, breweries, dairies, oil mills, and the drug industry to produce the fertilizer. The mix is normally approximately 80% animal manure and 20% organic material. The farms that provided the animal manure can use the fertilizer or it can be sold to any farm or industry wishing to replace chemical fertilizer with a cheaper alternative. Biogas plants also produce a gas through an anaerobic digestion process. Heating and power plants can use the gas produced to produce to create energy. Generally the raw waste material is transported to the biogas plant for disposal. The waste then undergoes anaerobic digestion." FROM: BIO-GAS PLANTS AND HOG FARMING IN NORTH CAROLINA
Asked in Pigs
Why is a pig smelly?
This smell is due to the amount of proteins that the pigs are eating and the microorganisms that are present in the manure. These microorganisms that are found in manure are anaerobic, meaning that they begin to work in the presence of air; they will break down and degrade the manure. This process is what causes the bad odour of the manure. The more protein that the animal is fed, the more microorganisms that will be present, causing more rancid smells.

Converting agricultural wastes into useful purposes?
Asked in Soil
What are the solution to soil degradation?
The best way is to grow leguminous plants. We should use natural manure instead of fertilizers. Manure increases the yield year by year slowly, but fertilizers give a good yield for a few years and then, the soil slowly degrades. Farmers should be well-educated of the harms of fertilizers. Biodegradable wastes can be dumped into a pit, this increases the nutrients in soil.
Asked in Hydrocarbons
How do you form methane gas?
methane is the first (and most simple) of the homologous series known as alkanes. It can be formed many ways of which some are --> i) catalytic cracking --> in this process large alkanes are broken down into smaller simpler alkanes and alkenes (of which methane is one) ii) biogas/manure --> in the process of fermentation or anaerobic digestion of manure, about 50% to 75% of the gas released is Methane gas iii) fractional distillation of crude oil/petroleum --> methane is obtained in the top fraction in the fractional distillation of crude oil or petroleum.
