  1. I. Introduction A. The Greenhouse • an environmentally controlled structure designed for the production of plants.

  2. B. Greenhouse Advantages • Control of • Aerial Environment • Light intensity • Temperature • CO2 • Day length • Humidity • Air circulation • Root Environment • Growing media - air and water • Irrigation • Fertilization • Insect and disease

  3. Almost every factor required for plant growth regulated for maximum production. • Growth rooms with optimum lighting in the future represent completely controlled environments. • Production of 5 times the quantity of a product than can be grown in field environment.

  4. Crops Produced in Greenhouses • All Plants • Flowering crops • Cut flowers • Pot plants • Bedding plants • Foliage plants

  5. Vegetable and fruit crops • Lettuce • Cauliflower • Tomatoes • Strawberry • Broccoli • Cucumbers • Radish • Nursery crops • Propagation • Overwintering • Growing

  6. What Determines Greenhouse Location? 1. Market • Developed and industrialized countries • Large population • Product • Size • Competitors • Price • Quality

  7. 2. Climate • Light • Temperature • Weather • Pollution

  8. 3. Transportation 4. Low production costs • Fuel • Labor • Water • Electricity • Taxes • Government support

  9. 5. Import restrictions 6. Site • Air movement • Drainage • Soil • Convenience • Zoning

  10. 7. Funding • Production credit • Farmer's home Adm. • Land bank • Banks • Entrepreneur

  11. 8. Abilities of owner • Manage • People • Money • Production • Market product • Competitive ability

  12. E. World Greenhouse Acreage • United States • Japan • The Netherlands • West Germany • Great Britain • Italy

  15. Problems facing industry • Fuel cost- heating, electricity, transportation • Labor - availability & cost • Pesticide use – availability & restrictions • Water - quality & available • No runoff

  16. H. Future-increase protected crop production • Increasing ultraviolet radiation on plants • Decreasing fresh water supplies and quality • Increasing erosion of top soil and degradation • Increasing problems with insect pests and diseases • Global climate changes
