AIM SWBAT DESCRIBE THE ADVANTAGES OF GROWING PLANTS
AIM: SWBAT DESCRIBE THE ADVANTAGES OF GROWING PLANTS HYDROPONICALLY Please Do Now: Name all 7 plant macronutrients.
Agenda � � Do Now Mobile vs. Immobile nutrients Hydroponic Intro Hydroponic video
FYI � � � The next exam will be Tuesday It will be short (35 -40 min), but still count as a test grade We will review Monday
What does it mean for nutrients to be mobile or immobile? � � Mobile nutrients can be relocated from old leaves to newer, more important leaves As such, deficiencies in mobile nutrients appear first in the older leaves from which they have been removed Immobile leaves are the opposite, they cannot be moved once they have been incorporated into tissues Deficiencies in immobile nutrients affect the young leaves first
Mobile vs. Immobile MOBILE � � � � Nitrogen Potassium Phosphorus Magnesium Chlorine Zinc Sodium Molybdenum IMMOBILE � � � Calcium Sulfur Iron Boron Copper
Mobile vs. Immobile MOBILE IMMOBILE
What is Hydroponics? � Hydroponics is the growth of plants with their roots submerged in an aqueous (water based) solution instead of soil
Hydroponics � This is possible because all the nutrients that a plant normally gets can be dissolved in the water that sits around their roots
Hydroponics � This also can allow us to isolate the effects of individual nutrients by including them in the solution and not in others.
Hydroponics PROS � � � Easy to control the nutrient environment of the plant to get optimum growth Plants get the nutrients more efficiently than if they have to search through soil for them Can result in faster/bigger growth CONS � � Labor intensive/lots of work Plant roots use oxygen, so you have to keep the dissolved oxygen in the water high or the roots will “drown” and die
