Cow-dung was then added in treatment groups with or without O. australis. Some treatment groups even had two out of the three nutrients supplemented in the pots. Comparisons of the treatment and control groups were made to show that top growth and roots significantly increased when the dung was mixed well into the soil in the pots.
Cow burps and manure emit the potent planet-warming gas, which over a shorter period is much more powerful than carbon dioxide. In recent decades, digesters that convert manure and other organic ...
New York dairy farms are using clean gas produced by cow manure, putting it in trucks, injecting it into an interstate pipeline — and selling the environmental benefits across the country.
Methane biogas derived from cow manure is being tested in the U.S. According to a 2008 study, collected by the Science and Children magazine, methane biogas from cow manure would be sufficient to produce 100 billion kilowatt hours enough to power millions of homes across America. Furthermore, methane biogas has been tested to prove that it can ...

Horses mainly eat grass and a few weeds, so horse manure can contain grass and weed seeds, as horses do not digest seeds as cattle do. Cattle manure is a good source of nitrogen as well as organic carbon. [3]
