Organic vs. Sustainable Agriculture
Agriculture, to many is just an industry of farmers and cows. Most people can’t even come close to fathom just how essential the continuance of agriculture is to not just our well being, but our very lives. People of the United States have been spoiled, they’ve never had to worry about the grocery stores running empty because, even to this day, there hasn’t been a problem growing enough to feed, not only the U.S. but a good part of the world too. The day though is fast approaching that we won’t be able to keep those grocery stores stocked. Due to the depletion of the vital resources, needed to produce our food, it is becoming increasingly challenging for today’s agriculturalists to feed the world. The only way to be able to keep up with the exponentially growing population and shrinking resource base, is to radically change how we produce our food or we will be looking at a huge crisis in the very near future. From this, need of new farming and production techniques, comes a couple new practices that will be discussed in this publication. One is sustainable, and the other is organic crop production. In the following, both practices will be discussed in detail hopefully clearing the air on which practice, in the long run should be the path production agriculture takes.
Organic Agriculture, as defined by the National Organic Standards Board (NOSB): “Is an ecological production management system that promotes and enhances biodiversity, biological cycles and soil biological activity. It is based on minimal use of off-farm inputs and on management practices that restore, maintain, and enhance ecological harmony.” Which is very fancily put for agriculture with as little man made input as poss...

The farm uses a cycle of animals, which include cows, chickens, turkeys, bunnies, and pigs, in order to keep the land fertile which allows for little use of external human made input. Polyface farm also takes hours of work everyday to upkeep unlike factory farms where it’s mostly automated. The farm also makes use of forested areas and other non-farmed resources, which forces them to protect that land from being cut down to receive those benefits. However, organic farming’s limiting factor is human population growth and the resources needed by the growing population.
Organic fertilisers and natural pest control methods minimise the impact of viticulture on the environment. In recent years there has been a considerable movement by some growers towards an organic approach. This is as a result of consumer driven trends and pressure to minimise the environmental impact of viticulture.

Organic refers to the way agricultural products, food and fiber, are grown and processed. “It is an ecological system that at its core relies on a healthy rich soil to produce strong plants that resist pests and diseases. Organic farming prohibits the use of toxic and persistent chemicals in favor of more “earth-friendly” practices that work in harmony with nature. In the case of livestock, antibiotics are prohibited, opting instead for preventative measures for keeping animals healthy and productive. Organic production also prohibits the use of genetically modified organisms (GMO’s).” (Ameriorganic) To find organic products one must only look for the U.S. Department of Agriculture (USDA) seal. The seal certifies the product must be 95%
With the world’s population continuing to increase, the demand for food is higher than ever. This increase in food demand also calls for more efficient ways of growing and providing the food. Two methods that are very controversial are the organic and conventional method. While many people support the organic method because of its known benefits, others feel that it is an over inflated industry that cheats consumers out of their money. But recently many studies have disproved those critics. These studies prove that Organic food is a better choice than conventional because it is better for the environment, avoids the use of chemicals, and is generally more beneficial.
With the rapid growth of our global population pouring into the next millennium, we will witness an ever-growing hunger rate around the world. That is unless we call for a revolution on the global scale. The Green Revolution which already sprouted in the early part of the century only need to add a bit more momentum and we will see a bright future for the human race, a future without hunger and starvation ¡V hopefully.It is becoming increasingly difficult for the planet to support its overwhelming population. And since the amount of arable land available is becoming scarce, we must seek ways to dramatically improve crop yields of existing cropland.
Organic foods are those grown without the use of growth hormones, antibiotics, synthetic pesticides, or chemical fertilizers. Genetically modifying crops is also not preformed in organic farming. Soil fertility can be maintained using crop rotation, cultivation practices, and cover crops. Natural fertilizers and pesticides are still considered to be included in organic farming (Winter & Davis, 2006). Products that are controlled with cultivation conditions rather than chemical-synthetic pesticides include organic products (Woese, Lange, Boess & Werner Bogl, 1999). The use of synthetic pesticides and materials falls under conventional farming. If the materials are on the National List of Allowed and Prohibited Substances, it can, however, be considered organic. A process that chemically changes a substance extracted from naturally occurring sources is considered a synthetic material (Winter & Davis, 2006).
The twentieth century brought significant changes to our planet. Humanity increasingly relies on fossil fuels and chemicals to grow what nourishes us: our food. At the same time, the world has become an urbanized place. More than half of the world’s people now live in urban areas (UNFPA, 2007). We have become disconnected from nature and natural processes. However, there is a new awareness of how to live in balance with the earth cropping up across the globe. Sustainability has become a way of life. There are now many organizations dedicated to promoting sustainable practises. World Wide Opportunities on Organic Farms (WWOOF) is one of these organizations.
For years organic farmers and conventional farmers have feuded over which is superior. Organic farmers argue that their product is more eco-friendly because they do not use the synthetic chemicals and fertilizers conventional farmer’s use. Conventional farmers argue that their product is healthier and yields more. People tend to have stereotypes regarding the two types of farmers. Organic farmers are usually thought of as liberal, hippy, tree-huggers while conventional farmers are usually thought of as right-wing, industrialists. Obviously, some do adhere to this stereotype, but a majority of these farmers are normal, hardworking people. Although these farmers, both believe in their methods, one is no better than the other. There are advantages and disadvantages to both, but there is no true superior method of crop farming.
A study of 362 datasets found that organic agriculture produces 80% of conventional yield with 21% standard deviation (Tomek et al. 2012). Second, organic farming requires less energy input which equates to less money spend from the farmers in addition to lowering carbon emissions. A study by the Department of Environment shows that organic agriculture uses 25 percent less than energy than their chemical counterparts, and certain crops like organic leeks and broccoli use 58 and 49 percent less, respectively (Bialis et al. 2013). Third, organic farming does not use pesticides. According to the World Health Center, 20,000 people die annually from the exposure of pesticides (Costa et al. 2014). Fourth, the methods that organic farmers use are better for the environment in the long run. And lastly, organic farming creates more jobs. A study done in United Kingdom shows 93,000 jobs could be created if Britain were to make a full scale shift to organic farming (Herro 2006). Although conventional agriculture is the primary producer for food currently, a large scale shift to organic agriculture is better suited to feed the world because organic agriculture can produce at adequate yield, requires less energy input, do not use
The term “organic” is almost everywhere in modern society, whether it’s used to promote a product or it’s debated on whether it really benefits the human diet. Organic food is heavily debated on as it appears more and more in local grocery stores and farmers markets begin to populate, it raises questions such as “Is organic food better than food grown with pesticides and biologically engineered genes?” and “Are there benefits to eating organically over foods grown in any other way?” In terms of what data and results show in research may help lead to answers to most of the heavily debated issues throughout discussions on organic food.
In today's grim economy and moving forward into an uncertain future, an increasing number of people have started using organic gardening as a means to grow some of their own food. While this was once a common practice during the Victorian era, organic gardening has made quite the come back in the past couple of years. In fact, Americans all across the country are taking advantage of everything from vacant lots to their own backyards.
Sustainable agriculture integrates three main goals--environmental health, economic profitability, and social and economic equity. A variety of philosophies, policies and practices have contributed to these goals. People in many different capacities, from farmers to consumers, have shared this vision and contributed to it.
Agriculture is one of the most ancient forms of art and science that ties human development and well-being to natural resources and ecosystems. (Fritz J. Häni, 2007) Sustainable Agriculture is the production of food, fibre, plant and animal products using farming techniques that protect the environment, public health, human communities and animal welfare. (Sustainable Agriculture - The Basics, 2015) Sustainable agriculture is an integrated system of plant and animal production practices having a site – specific application that over the long term will:
