Transcript of Organic Farming
reduce the risk of Bioaccumulation? Bibliography Practises Used In Organic Farming There are many different practices used in organic farming and each have variations depending on the farmer. They all have a basic structure or backbone that each farmer can change to his or her liking or preference. That is as long as they avoid the use of harmful chemicals to kill off insects damaging their crops or to make their crops grow better. Organic Farming collaborates with nature to make plants grow better or to stop insects from damaging crops. It avoids the use of dangerous chemicals that can be harmful for the environment and humans in growing crops. Traditional farming practices based on thousands of years of agriculture are combined with scientific knowledge and modern technology in organic farming methods. Organic Farming, also known as Biological farming in some countries, is catching on pretty quickly in many large-scale farms all around the world despite claims that it isn’t practical for commercial farms, and is only applicable in backyard gardens and small farms. So why should organic farming methods be used more in agriculture? Well, here is some reasons as to why organic farming and food are good and should be used more. Environmental Chemistry •Biodynamic – Possibly the oldest known method of organic farming this century and is mentioned as the Biodynamic Method. It was developed by Rudolph Steiner in Germany during the 1920s. The farming routines are connected to the lunar and planetary phases and plant and mineral based formulations are often sprayed on crops to provide the necessary nutrients. Bioaccumulation is basically accommodated to measure the uptake of toxic substances that can stay in a biological system (plant, animal) over time. With humans being at the top of the food chain, we currently consume the highest rate of pesticide concentration. Roughly 165 active ingredients permitted for pesticide products are known human carcinogens. Carcinogens are products that has the potential to cause cancer. Pesticides in food cause 1.4 million cancer cases in the United States, as approximated by a recent US Academy of Sciences’ study. http://www.infonet-biovision.org/res/res/files/488.OrgFarm.pdf

It limits the amount of chemicals used, especially the harmful ones. Organic food are grown without any dangerous chemicals and because of this farmers and their families don’t get contaminated. 2.Organic farming is sustainable and eco-friendly. It’s not destructive to Mother Nature and the superb variety of living organisms on it. 3.If a food is classified as an organic foods it usually is free of pesticide or other synthetic chemical remains. While it is unclear as to what the long term effects of eating slightly contaminated food are, high levels of pesticide deposit can kill or poison people, and lower deposits can cause cancer. 4.Another benefit of farming organically and buying things from farms that use organic methods, is the guarantee that the produce does not contain genetically modified organisms. Standard organic farms have broad crop rotation as a requirement for the resourceful use of resources that are on the farm. Farmers select plants and animals that are resilient to disease and are adapted to the local environment. They also have very strict limitations on the use of chemical synthetic pesticide and synthetic fertiliser, livestock antibiotics, food additives and processing aids. Organic farms have a total ban on the use of genetically modified beings and use livestock manure for fertiliser, feed (for cattle) produced on the farm, etc. Farmers of these farms also breed livestock in free-range, open-air systems and provide them with organic feed. Some recognized variations of the basic method of organic farming are: •The Rodales – Developed the J.I Rodale as he searched for alternative farming methods in the early 1940s. He saw the recommendation of that time to treat crops with chemicals as harmful and senseless. Rodale stressed that organic agriculture was related to human health as it had reduced exposure to pesticides and produced nutrient rich vegetables. •Biointensive – This method was frequently outlined by John Jeavons in the book “How to Grow more Vegetables Than You Ever Thought Possible on Less Land Than You Can Imagine” (1995). Some key principles of this method are high organic matter, growing organic matter exactly for soil building, deep crop growing or double digging and extremely high harvests per unit of production. •Natural Farming – This method of farming is based on building soil with regular surface treatments of organic matter with little or no nurturing. Organic matter is approved to slowly decompose on the surface as opposed to composting in mountains. Natural Farming was popularized by Masanobu Fukuoka in Japan. Organic Farming reduces the risk of bioaccumulation immensely. It does not allow the use of harmful chemicals such as those found in pesticides to grow and cultivate crops. By doing so, the exposure to chemicals is reduced on many levels as we are protecting ourselves from consuming harmful by-products and also creates a healthier work environment for the farm owners and labourers. It also reduces the amount of chemicals in animals which humans consume. When animals consume crops grown following organic farming methods, they have little or no chemicals in them and as it goes up the food chain the amount of chemical consumed by each animal is reduced significantly if not there being an absence of chemicals.
