rotated in a way that replenishes the soil. Manure and chemical fertilizers are used to “feed” the soil‚ but through over-application these additives become a problem. Manure carries with it other substances that are used on industrial farms. These include antibiotics and artificial growth hormones‚ which contaminate waterways and affect the plants and animals that live in them according to Salt‚ a common component of manure from industrial dairies‚ can damage soil quality

concentrated animal populations in the Unite States produce around one hundred and sixty million tons of fecal waste per year.Sixty percent of that manure is spread directly onto the crop land ‚causing the nitrogen levels in the soil to exceed the absorpitive capacity of the crops‚then polluting the nearby rivers ‚lakes ‚ground water and land.The manure lagoons also emit toxic chemicals that can result in many human health problems ‚such as respiratory disease‚skin rashes‚and headaches.The fecal waste

biodiesel). Biomass is one of the biggest green energy sources in the world. Converting Biomass‚ first goes through chemical and thermal to mechanical and finally to electrical. That is the process we use when we burn biomass. So an example would be cow manure and that would be changed into fuel. How? Well there is this process called Anaerobic digesting. This process is when microorganisms break down‚ in a no oxygen environment‚ material that is biodegradable. Biodegradable means that

as all mammals do‚ have to rid themselves of their manure. Now imagine all the cars in the world in fact being horses. As horrible as it is to imagine‚ now think about the amount of manure that would be produced around the city. Not only would it be disgusting to look at and the smell would be unbearable‚ manure carries lots of unwanted parasites and diseases. I don’t know about you‚ but I wouldn’t want to fight my way through mountains of manure everyday just to try and get to work/school

Biofilters work by absorbing noxious gases into a biofilm where microorganisms break down the gases into carbon dioxide‚ water‚ and salts and use the energy and nutrients to grow and reproduce. Well-designed and managed biofilters

The Savagery Of Factory Farming Factory Farming is not only feeding us‚ but destroying us and our only world! Worldwide‚ about 70 billion farm animals are now reared for food each year. This mass production of food uses many antibiotics to speed up the birth process‚ but those antibiotics are still in the meat we eat. The waste and space from the factory farms destroys the environment and is also a danger to human health. The factory farming of animals has a negative impact on human health

nitrogen requiring cereals such as wheat and maize. This method reduces the need of fertilizers‚ thereby increasing the overall yield of crops. Question 2: Why are manures and fertilizers used in fields? Answer: Manures and fertilizers are used in fields to enrich the soil with the required nutrients. Manure helps in enriching the soil with organic matter and nutrients. This improves the fertility and structure of the soil. On the other hand‚ fertilizers ensure a healthy growth
