2 From Dirt to DNA Agriscience Applications

3 What is Agriculture? Activities concerned with the production of plants and animals, and related supplies, services, mechanics, products, processing, and marketing.

4 USDA refers to agriculture as…. “Agriculture/ Agribusiness and renewable natural resources”. Another definition is food, fiber, and environmental systems.

5 What is Agriscience? The application of scientific principles and new technologies to agriculture.

6 Agriscience is…… An applied science because it uses principles learned in biology, chemistry, and physics (the basic sciences) in a practical way.

7 Examples of Applied Sciences Agronomy Uses biology and chemistry to discover new ways to control weeds in crops. Entomology Uses biology and chemistry to study insect life. Agricultural Engineering Uses physics to develop new machinery. Saw Stop

8 Agriscience employs….. The scientific method to solve problems. The steps to the scientific method are…. Identify the problem. Review literature. Form a hypothesis. Prepare a project proposal. Design the experiment. Collect the data. Draw conclusions. Prepare a written report.

9 Why is Agriculture/Agriscience Important? Largest “employer” and the largest source of income in the United States and North Carolina.

10 Opportunities in Agriculture Agricultural production is supported by many more careers than actually exist in production. Many careers in agriscience products & distribution are needed to grade, transport, process, package, & market agriculture commodities. Products, Processing & Distribution Projections show that the average size of farms in the U.S. will increase while the number of farms will decrease.

11 Opportunities in Agriculture Twenty percent of all jobs in the U.S. are agriscience related. In addition to farming, agriscience jobs help support farmers to meet the world’s food & fiber needs. Areas include: Production Processing, products, and distribution Supplies and services.

12 World Outlook The world population will grow as more people beget more people. More children are surviving to adulthood. More adults are living longer. Population growth will…. Add stress to environmental systems of air, water, soil, and natural resources. Create challenges to meet the demands for food and fiber (clothing and shelter).

13 Trends for Agriculture/Agriscience Agriculture will always be an essential industry. Increased commercialization of agriculture will continue. New types of farming such as aquaculture (fish farming and farming the sea) will be used as well as traditional farming methods.

14 Trends for Agriculture/Agriscience An expanded view of agriculture is necessary.

70 Assignment With a partner you must design a new agricultural invention. Requirements: Must be something that has not already been invented. Must have a name and price. Must have a color picture. Must include a four sentence description of the invention and how it works.

71 Improving Life through Agriscience Soybeans Known as the “Yellow Jewell” to the Chinese. World’s most important source for vegetable oil. Provide basic materials for hundreds of products. Used as major food source in China in the form of tofu.

72 Improving Life through Agriscience The Green Revolution Process whereby many countries became self sufficient in food production in the 1960s by using improved crop varieties and practices.

73 Improving Life through Agriscience The Green Industry The modern horticulture industry with emphasis on turf and landscape plants.

74 Agriscience and the Future The average American farmer produces enough food and fiber for 128 people. As the world’s population increases, it will require a more sophisticated agriscience industry to keep pace with demand.

75 Agriscience and the Future The science of food production, processing, and distribution will require: College graduates to fill roles as scientists, engineers, and other professionals. USDA reported an increased demand for graduates from agricultural colleges in the 90s.
