As National Dairy Month wraps up, the American Biogas Council (ABC) today released new data highlighting the rapid growth in methane capture through the use of biogas systems at U.S. dairy farms. Biogas systems trap the methane that is produced naturally when dairy manure breaks down, allowing this gas to be used for fuel. This ...
If you can handle cow manure well, it will pay you well for the money, not just the bad smell. ...
Dairy manure has also been tested for topdressing wheat fields as part of on-farm research trials.

According to the ...
Environmental Protection Agency and their partner agencies in the California/Federal Dairy Digester Working Group have announced a joint solicitation for dairy digester concept proposals. California is the largest dairy state in the USA, with approximately 1.7 million cows producing more than 3.6 million dry tons of manure per ...
A nearby corn field contains tools that allow researchers to assess the effects of manure spread as fertilizer. Scientists based at the University of Wisconsin-Madison have started a slew of studies to determine how dairy farms can reduce their greenhouse gas emissions. ...
A Dorset farmer has been ordered to pay £16,339 in fines and costs for polluting a tributary of the River Divelish with slurry. The case was brought by the Environment Agency. The pollution was first discovered during a routine inspection of the river on September 20, 2012.

A ...
The study also suggests that growers who want to transition to organic production while minimizing tillage may experience variable economic success depending on how they begin their rotation. Costs associated with manure and compost, which was purchased off-farm, also strongly influenced the economics of the systems. The authors conclude that integrated systems that include field ...
In addition to reducing the solubility of phosphorus, this method shows particular promise for researchers interested in tracking the fate of manure nutrients in agricultural settings. Led by Anthony Buda, a team of scientists from the USDA Agricultural Research Service and the Chinese Academy of Sciences applied two rare earth chlorides (lanthanum chloride and ytterbium ...
