Cutting Edge Technology
Dr. Bruce Dunn showcasing some of the new technology of rolling benches, LED lighting, blackout and an automated climate control system that students will utilize in classes to Rob Haddock and Dr. Cynda Clary, Associate Dean of the Ferguson College of Agriculture. The Kalanchoe in the picture is used in the Principles of Horticulture class for demonstrating propagation using a viviparous leaf.
Deep Water Culture
Students are learning and developing deep water culture plants. The plant's roots are suspended in an oxygenated nutrient solution. Soil provides gaps where air is present, thus the water needs to be oxygenated for the plants to survive. Soil also contains macro and micro nutrients for the plants so in hydroponics the oxygenated water is supplemented with nutrients. In a deep water culture, the deeper the water level the more stable the nutrient solution will remain.
Nutrient Film System
Matthew Beartrack seen checking on the nutrient film system. This technique uses a water pump to deliver a constant flow of shallow, nutrient rich solution through the growing area and drains directly back into a reservoir. The growing trays are placed at an angle (supported by a rack or on a bench) to let the nutrient solution flow back into the reservoir.
