  1. USING APPLIED SCIENCEAND TECHNOLOGY BY HOWARD HENDERSON CHAPTER 2 AGRISCIENCE/TECHNOLOGY

  2. DEFINITION OF AGRISCIENCE • IT IS THE USE OF SCIENCE IN PRODUCING FOOD, FIBER AND SHELTER • APPLIED SCIENCE ANSWERS THE QUESTION “WHAT SHOULD I DO?” WHAT CHEMICAL TO USE • BASIC SCIENCE ANSWERS THE QUESTION “WHY DOES IT DO WHAT IT DOES?” EX. WHY CHEMICAL WORKS

  3. TECHNOLOGY • PRACTICAL USE OF SCIENCE-USUALLY INCREASES FOOD PRODUCTION • DEVELOPMENT OF BST IN DAIRY TO INCREASE THE AMOUNT OF MILK ONE COW WILL PRODUCE *ADVANTAGE - LESS COWS NEEDED*DISADVANTAGE - LESS DAIRY FARMERS NEEDED

  4. LEADERSHIP AND TECHNOLOGY • AGRISCIENTISTS AND GOVERNMENT OFFICIALS OFTEN MAKE DECISIONS ABOUT WHAT WILL BE AVAILABLE • EXAMPLE WOULD BE IN THE US MONSANTO DEVELOPED A SOYBEAN THAT PRODUCES STERILE SEED;THEY DECIDED NOT TO PUT IT ON THE MARKET

  5. FOUR AREAS OF SCIENCE • MATHEMATICS - WEIGHT TO BUY AND SELL A PRODUCT; LAND SURVEYING • PHSICAL SCIENCE - NONLIVING MATTER EARTH SCIENCE/CHEMISTY/PHYSICS EXAMPLE ACCURATE WEATHER/FERTILIZER/LOADING RAMPS

  6. FOUR AREAS CONT. • LIFE SCIENCE - STUDY OF LIVING THINGS INCLUDES BOTONY AND ZOOLOGY • WAYS TO MAKE PLANTS AND ANIMALS GROW BETTER • SOCIAL SCIENCE -BEHAVIORAL SCIENCE: WHY PEOPLE RESPOND AS THEY DO TO FOOD

  7. AGRONOMY • DEALS WITH THE STUDY OF PLANTS AND HOW THEY RELATE TO THE SOIL • PURPOSE IS TO IMPROVE CROP PRODUCTION AND CONSERVE NATURAL RESOURCES

  8. HORTICULTURE • SCIENCE OF GROWING FRUITS,NUTS AND VEGETABLES • ALSO INCLUDES FLOWERS AND ORNAMENTAL SHRUBS AND VINES

  9. FORESTRY • SCIENCE OF GROWING AND USING FORESTS • TWO TYPES OF FORESTS : CULTURED - TREES ARE PLANTED AND CARED FOR • NATIVE - TREES THAT GROW WILD;USUALLY A MIXTURE OF TYPES

  10. ENTOMOLOGY • BRANCH OF ZOOLOGY THAT DEALS WITH INSECTS AND RELATED SMALL ANIMALS • INCLUDES BENEFICIAL INSECTS -HONEYBEE • HARMFUL INSECTS - CORN BORERS

  11. ANIMAL SCIENCE • AREA OF AGRISCIENCE DEALING WITH THE PRODUCTION OF ANIMALS FOR FOOD • ANIMALS USED FOR MEAT INCLUDE CATTLE, HOGS, SHEEP, GOATS, BISON, EMUS AND LLAMAS

  12. POULTRY SCIENCE • AREA DEALING WITH RAISING CHICKENS AND RELATED FOWL(BIRDS) • MOST IMPORTANT - CHICKENS • OTHERS INCLUDE - TURKEYS, DUCKS, GEESE, PHEASANTS, QUAIL, AND GUINEA

  13. AQUACULTURE • IS THE SCIENCE OF WATER FARMING • DEALS WITH BOTH AQUATIC PLANTS AND ANIMALS • EXAMPLES OF PLANTS - WATER CHESTNUTS AND WATER CRESS • EXAMPLES OF ANIMALS - TROUT AND ALLIGATORS

  14. ENVIRONMENTAL SCIENCE • INVOLVES WAYS OF WISELY USING AND PROTECTING THE THINGS AROUND US • EMPHASIS IN ENVIRONMENTAL SCIENCE INCLUDE THE AIR, SOIL, WATER, WILDLIFE, NATIVE PLANTS AND MINERALS

  15. MECHANICAL TECHNOLOGY • INVOLVES THE USE OF MACHINES AND EQUIPMENT TO DO WORK • EXAMPLES ARE DEVELOPING : TRACTORS, GREENHOUSES, PONDS, HARVESTING EQUIPMENT,ETC.

  16. SCIENTIFIC METHOD • FIVE IMPORTANT STEPS • STEP ONE : IDENTIFY THE PROBLEM EXAMPLE - TOO MUCH BACKFAT IN LOCAL PIGS USED FOR SLAUGHTER • STEP TWO : GET INFORMATION EXAMPLE - COLLECT DATA FROM SLAUGHTER HOUSES IN AREA

  17. SCIENTIFIC METHODCONT. • STEP 3: SUGGEST AN ANSWER EXAMPLE - USE A SUPERIOR BOAR ON AREA SOW HERDS • STEP 4 : EXPERIMENT • EXAMPLE - FEED OUT OFFSPRING AND COMPARE CUT OUT DATA • STEP 5 : FORM CONCLUSIONS EXAMPLE - NEED TO USE NEW GENETICS IN OUR AREA

  18. RESEARCH • AGRISCIENCE RESEARCH IS CARRIED OUT BY LAND-GRANT UNIVERSITIES, AGRICULTURAL AGENCIES, AGRIBUSINESSES AND OTHER GROUPS • A FEW FARMS DO RESEARCH

  19. NEW AREAS OF AGRISCIENCE • BIOTECHNOLOGY • GENETIC ENGINEERING • REMOTE SENSING • LASER TECHNOLGY • COMPUTATIONAL SCIENCE • RADIATION

  20. BIOTECHNOLOGY • EXAMPLES OF BIOTECH : • DEVELOPING VACCINES • PRODUCTS THAT WILL CAUSE LIVESTOCK TO PRODUCE MORE MEAT ON LESS FOOD • DEVELOPING BACTERIA THAT WILL CONSUME WASTES

  21. GENETIC ENGINEERING • DEVELOP CROPS THAT ARE INSECT RESISTANCE • DEVELOP A TOMATO THAT IS ROT RESISTANCE • DEVELOP A CROP PLANT THAT KILLS THE WEEDS AROUND THEM

  22. REMOTE SENSING • INVOLVES GATHERING AND RECORDING DATA FROM A GREAT DISTANCE • WEATHER INFORMATION • RESOURCE LOCATION • CROP PESTS • PROTECTING NATURAL RESOURCES

  23. LASER TECHNOLOGY • A DEVICE THAT PRODUCES A SPECIAL KIND OF LIGHT • LAND FORMING • MONITORING PROCESSES • SCANNING - SUPERMARKETS

  24. COMPUTATIONAL SCIENCE • USING COMPUTERS TO SOLVE PROBLEMS IN AGRISCIENCE • DESIGNING FACILITIES • DEVELOPING PRODUCTS • MODELING NATURAL RESOURCES

  25. RADIATION • USE OF RADIATION • PREVENTING SPOILAGE OF FOOD BY KILLING BACTERIA THAT MAY BE ON OR IN A FOOD PRODUCT • KEEPING INSECTS OUT OF STORED FOOD

  26. ISSUES ASSOCIATED WITHAGRI/TECHNOLOGY • FOOD SAFETY • POLLUTION • CONSERVATION OF RESOURCES • HUMAN RIGHTS : EXAMPLE - FOOD PRODUCTS SHOULD NOT BE IMPORTED FROM A NATION WHERE PESTICIDES ARE BEING USED IMPROPERLY
