Hydroponics Plant and Soil Science Plant Science Technology Lesson 3
Aggregate Culture • material such as sand, gravel, or marbles support the plant roots.
plant roots are immersed in water containing dissolved nutrients. Water culture, solution culture, or nutriculture
plant roots hang in the air and are misted regularly with a nutrient solution Aeroponics
nutrient solution flows constantly over the plant roots. Continuous-flow system
Hydroponics is growing in importance as a means of producing vegetables and other high-income plants
Plant Growth Requirements • Water • Oxygen • Mineral Nutrients • Needed in large quantities • nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. • Needed in tiny amounts • iron, manganese, boron, zinc, copper, molybdenum, and chlorine. • Light • Need 8 – 10 hours to produce well • Spacing • Temperature • Support
