Research Stanford University has held over 250 investigations that compared the nutritional value of organic and traditional crops. These studies show that organic foods tend to contain slightly more phosphorous‚ a higher level of omega3 fatty acids‚ and a 30% lower rate of chemical residue. However‚ traditional chicken and pork is onethird more likely to contain antibiotic bacteria than

DEDICATION This thesis is dedicated to my family and friends‚ who have been with me through the years‚ in times of good and bad. v ABSTRACT The conventional farming model has been the agriculture industry’s preferred method of cultivating crops since the 20th century (“Conventional Farming”‚ n.d.). This model advocates the use of heavy machinery‚ chemicals and vast amounts of energy input. So far‚ the expenses have been justified in the results as conventional farming has been extremely productive

In the 1930s‚ poor land management and neglectful farming practices led to severe soil erosion in the mid-western farming regions of the United States. Several non-eco-friendly farming practices led to severe topsoil erosion and depletion of minerals in the soil needed to maintain plant life. Without windbreaks to protect dry soil‚ lack of root systems to hold the soil into place; winds swept through the barren fields creating dust storms that carried precious topsoil across the country. The dust

When the Wall Street stock market crashed in October 1929‚ the world economy was plunged into the Great Depression. By the winter of 1932‚ America was in the depths of the greatest economic depression in its history. The number of unemployed people reached upwards of 13 million. Many people lived in primitive conditions close to famine. More than 1‚000 people lived in shacks made from scrap metal and boxes. There were many similar Hoovervilles all over America. Between 1 and 2 million people travelled

The organic farming focus on keeping good soil structure and fertility‚ and the farmers need recycle and compost crop wastes‚ animal manures‚ crop rotation‚ and green manures.(Infonet‚ n.d.‚ para. 2).

agricultural development marked by new farming techniques and inventions that led to a massive increase in food production. The Agricultural Revolution brought about experimentation with new crops and new methods of crop rotation. These new farming techniques gave soil time to replenish nutrients leading to stronger crops and better agricultural output. Advancements in irrigation and drainage further increased productivity. It was also during this time that inventions were created that greatly increased

The control of planting seeds wit the seed drill was greatly improved that it saved seeds and allowed most of the plants to germinate at the same rate. This created increased crops and profits for the farmer. The results of the seed drill were greatly welcomed by most people. The growing population of the country sparked a new need for food and farmers. The trade between Europe’s main land and England were very limited
