among others. John Bennet Lawes‚ an English entrepreneur‚ began to experiment on the effects of various manures on plants growing in pots in 1837‚ and a year or two later the experiments were extended to crops in the field. One immediate consequence was that in 1842 he patented a manure formed by treating phosphates with sulphuric acid‚ and thus was the first to create the artificial manure industry. In the succeeding year he enlisted the services of Joseph Henry Gilbert‚ with whom he carried on

This type of technology has been experimented on what is called the Enviropig‚ invented which manupilates the genes to help produce less phosphorus in its manure‚ this is more efficiently than conventional Yorkshire pigs. The feces from the Yorkshire pigs were discovered that it contained large amounts of phosphuros‚ as they can not digest it. The new improved genetic modification Yorkshire pig was design

The boxes were placed in a lighted area while maintaining their moisture. After drying‚ the Lumbricus terrestris were gathered. The resultant product‚ called “earthworm castings‚” was then sun-dried and passed through a fine sieve to remove foreign materials. Results showed that the casting from kitchen wastes and manure was highest

They also use their hide for anything leather‚ rugs‚ and mats. Their hooves and horns help to make combs and brushes; and even the poop of the cows‚ pigs‚ horses‚ and whatever else there is‚ they don’t go to waste. Farmers use their poop to spread manure on their fields and pastures so their grass in the pastures and the crops in the field can get more nitrogen. That way the crops can grow more and be healthier. Feeding and breeding livestock has become well planned and they can be on a strict diet

Biogas Anaerobic Digester Considerations for Swine Farms in North Carolina Collecting biogas from anaerobic digestion of swine manure can benefit the environment by reducing methane emissions (has potential value for equivalent carbon credits or greenhouse gas (GHG) credits)‚ and by providing energy‚ as biogas is about 60 to 70 percent methane. Methane has an energy value of about 1‚000 BTU/SCF1‚ so biogas can have an energy value of about 600 BTU/SCF. Plug-flow or complete-mix anaerobic digesters

Manure contains high levels of phosphorus and nitrogen that increase the growth of plants‚ including invasive ones. The manure also creates perfect conditions for the growth of fecal bacteria‚ like E. Coli (Indiana Water). “To prevent pollution from livestock operations‚ CAFOs and the manure they generate should be barred from sensitive areas like floodplains and

streams. Same principle applies to the agriculture industry. There are many toxins that can be attributed to the farming industry. Some of the more toxic are fertilizers‚ manure‚ livestock waste and oil and other chemicals from the equipment. According to an article titled‚ “Pollution Potential of Livestock Manure”‚ raw manure is up to 160 times more toxic than raw municipal sewage. This causes great concern for all living creatures. When these toxins enter into our water supply they create
