  1. What Is Agriculture?Why Is It Important? Intro. To Agriscience Unit 1, Section A Mrs. Martin 2012-2013

  2. The Three A's Agriculture- The activities related to the production of plants, animals and related processes. Agribusiness- Refers to commercial firms that have developed from agriculture Agriscience- The application of scientific principles to agriculture

  3. What is Agriscience? • Agriscience is the application of scientific principles to agriculture. • 3 Basic Areas of Agriscience • Biology- The study of living things • Chemistry- Deals with elements and simple substances • Biochemistry- Focuses on chemistry as it is applied over living things.

  4. What is Agriscience? Technology- The application of science to an industrial or commercial purpose High Tech- The use of electronics and state-of-the-art equipment to perform task • Application of scientific principles and new technologies • Applied science • Uses basic sciences in practical ways • Biology • Chemistry • Physics

  5. What is the definition of Agriculture? • Agriculture also called farming or husbandry is the production and cultivation of animals, plants, fungi, and other life forms for food, fiber, biofuel and other products used to sustain life. • Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization. • The study of agriculture is known as agricultural science.

  6. What is Agriculture… Continued! • Agriculture is also known as the activities concerned with the production of plants, animals, and related supplies, mechanics, products, processing, and marketing. • Production agriculture (farming) only accounts for 1/5th of the total agriculture jobs in the US

  7. Agriscience Examples • Entomology • Uses biology and chemistry to study insect life • Definition: • Agriculture Engineering • Uses physics to develop new machines, tools and implements • Definition:

  8. Agriscience Examples • Agronomy • Definition: • Uses biology and chemistry to produce and control crops • Cotton • Soybeans • Tobacco • Corn • Hay and Turf grass

  9. Agriscience Examples • Biotechnology • Definition: • Uses biology, genetics, and chemistry to modify or change organisms for a useful purpose

  10. Applied Sciences • Aquaculture • Agricultural Engineering • Animal Science • Crop Science • Agronomy • Soil Science • Biotechnology • Horticulture • Hydroponics Definition- The application of one or more of the basic sciences for practical (real life) purposes.

  11. Definitions of Applied Sciences Aquaculture: • The raising of finfish, shellfish, and other aquatic animals under controlled conditions. • Also the management of aquatic environments for production of plants and animals. Agricultural Engineering: • The application of engineering principles in agricultural settings

  12. Definitions of Applied Sciences Animal Science: The science of animal growth, care, and management. Crop Science: • The use of modern principles in growing and managing crops.

  13. Definitions of Applied Sciences Agronomy: • The science and economics of managing land and field crops. Soil Science: • The study of properties and management of soil to grow plants.

  14. Definitions of Applied Sciences Biotechnology: • The use of cells or components of cells to produce products of processes. Horticulture: • The science of producing, processing, and marketing fruits, vegetables, and ornamental plants.

  15. Definitions of Applied Sciences Hydroponics: • The practice of growing plants without soil. University of Arizona Hydroponics Greenhouse, organic tomatoes.

  16. Fact: A United States Department of Agricultural study forecast that job opportunities for graduates in agricultural and life sciences will exceed the graduates available in the coming years.

  17. What is Agribusiness? • Refers to commercial firms that have developed out of agriculture • Take a moment to name three agribusinesses in your notes: • John Deere • Monsanto • Tractor Supply

  18. How important is agricultural trade to the U.S. economy? • The United States is now the world’s largest agricultural exporter. The value of agricultural exports equals nearly one-fourth of farm cash receipts, about twice the level of the overall U.S. economy, and 1 out of 3 acres are planted for export.

  19. How much of its agricultural products does the United States export? • American farmers export: • 45 percent of their wheat • 34 percent of their soybeans • 71 percent of their almonds • More than 60 percent of their sunflower oil.

  20. What would happen if US Agricultural Production stopped today? • In 3-5 days: The American economy would begin to collapse. • Most American homes do not have enough food to last more than 3 daysand not enough water on hand for more than 1 day. • Economic Example: Stock markets crashed after 9/11, driven by “the mood” (fears and confidences) of the public. • Emergency Example: Hurricane Katrina- Riots, looting, grocery stores bare in a matter of hours.

  21. What would happen… Continued. • In 5 -7 days: The entire World would begin to suffer the same economic collapse. • Humanitarian aid to 3rd World or war torn countries would have stopped completely. • Northern European countries that rely on imports from America would begin to suffer a food shortage. • Finland, Sweden, Norway: • No fruit? No meat? No veggies?

  22. Where would we be without Agriculture? Naked +Hungry=
