10
Technology

• Technology is the use of inventions in working
  and living.

11
Agricultural Technology

• Agricultural technology isthe technology used in
  agriculture.
• Mostly based on science.

12
Benefits of Ag Technology

• Agricultural technology has resulted in many new
  ways of producing
• Food
• Clothing
• Shelter

13
Technology has brought about many advantages in
agriculture.

• Technology makes work easier.
• Technology increases productivity.
• Technology increases the standard of living.

14
Mechanical Technology

• Mechanical technology is using physical force to
  do work. Devices are used topull, push, or
  rotate objects.

15
Agriculture Science

• Gregor Mendel studied the heredity of peas.
• He concluded that traits are passed from one
  generation to another.

16
Mass Selection

• Mass selection is saving seed from the best
  plants. In the mid-1900s hybridization began.

17
Hybridization

• Hybridization involves cross-breeding plants to
  combine the highest quality traits from each
  breed.

18
Pest Control

• Pest control technology has improved the quality
  of many agriculture products.
• A pest is anything that causes injury to animals,
  plants, or property.
• Pests may include insects, diseases, or weeds.

19
Pesticides

• Pesticides have made great strides from
  scientific research.
• A pesticide is a substance that controls pests.
• A pesticide can be a chemical or biological
  control.

20
Biological control

• Biological control involves using living
  organisms to control pests.

21
Insecticide

• An insecticide is a chemical substance used to
  control insect pests.

22
Advancements in Ag Science

• Cloning and genetic engineering are being used in
  plant production and improvement.

23
Cloning

• Cloning is making two or more organisms out of
  one using tissue.

24
Genetic Engineering

• Genetic engineering is artificially changing the
  genetic makeup of an organism.

25
New Avenues for Production

• New developments with fish have created a new
  area for agriculture, calledaquaculture.

26
Aquaculture

• Aquaculture is the production of fish or plants
  for human consumption.

27
Computers in Agriculture

• A computer is a machine that performs informative
  activities at a high speed.
• Computers are widely used in agriculture and
  horticulture.

28
Robotics

• Computers are used to operate robots.
• A robot is a machine that can do varioustasks.
• The robot receives its instructions from a
  computer which has been programmed a certain way.

29
Computer Applications in Agriculture

• Computers used in agribusiness to prepare plans
  for building new equipment, sending messages, and
  designing landscapes.

30
Precision Farming

• Precision farming is an information- and
  technology-based crop management system.
• It takes into account differences in the needs of
  crops in specific sites within a field.

31
Review/Summary

• Explain agricultural technology.
• Describe technology as it relates to machinery,
  plants, and animals.
• Describe the role of computers in
  agriculture/horticulture.
• Explain precision farming and its impact on
  agriculture.
