  1. SOIL It’s ALIVE!

  2. What is soil? Everyone share what you think soil is.

  3. Agenda: • What is soil and what does it do? • Soil Nutrients Needed for Plant Growth • Your Learning Garden Soil • Managing Soil Health

  4. What does soil do for us and plants? • Medium for plant growth • Home for organisms • Recycler of natural materials • Water filtration system • Modifier of the atmosphere • Structure holding up buildings

  5. Minerals Worm (OM) Air Soil Components: 25% AIR Organic Material (OM) 45% Minerals 25% WATER 5% OM Water

  6. The mineral content - Sand, Silt, and Clay: Sand 2.0-0.02 mm Silt 0.02-0.002 mm Clay <0.002 mm

  7. The Ribbon Test:

  8. Soil Structure: Water and Air: Half Water Half Air After Watering Not Watering

  9. !!! SOIL IS ALIVE !!! Organisms and Organic Matter Decomposes Physical Decomposer Chemical Decomposer

  10. Nutrients in the soil: Macro: Micro: Nitrogen Phosphorus Potassium Calcium Magnesium Chlorine Boron Iron Manganese Zinc Copper Molybdenum

  11. Macronutrients: The main ingredients needed for plant growth: Nitrogen (N) Phosphorus (P) Potassium (K) Vegetative growth DNA and RNA Root Development Seed Production Enzymatic Activities

  12. Micronutrients & Trace Minerals: Manganese 1.1 - 6.3 ppm Magnesium 50 - 120 ppm Boron 0.1 - 0.5 ppm Copper 0.3 - 0.6 ppm Calcium 1,000 - 1,500 ppm Molybdenum Iron 2.7 - 9.4 ppm Zinc 1.0 - 7.6 ppm Chlorine Chlorophyll Reproduction Oxidase Enzyme Photosynthesis Cell Structure Nitrogen Uptake Chlorophyll Photosynthesis Chlorophyll

  14. How do nutrients move through the env.?

  15. Spot the unhealthy plant: A. B. C. D.

  16. Spot the unhealthy plant: A. B. C. D.

  17. Spot the unhealthy plant: A. B. D. C.

  18. CLASS ACTIVITY: Soil Nutrient Card Game • Put 10 beads into each cup except for the water cup which gets 5. • Assign one member of your group to be the Bacteria/Fungi. • Shuffle the cards and place them in a stack. • Read the question on the front of the card and come up with an answer as a group. • Flip the card over and check you answer. • Move the amount of beads dedicated on the card. • Repeat until you have used all the cards in the deck. • What do you notice about the amount of beads in each category. • Remove the cards labeled 1 and 2 and replay the game. • What do you notice this time.

  19. Explore Your Learning Garden Soil! Big Question! Is it soil??? • What do you find in it? • What don’t you find in it? • How many parts of soil can you identify? • What does it feel, smell, and look like? • Does it form a ribbon?

  20. Maintain Soil Health: • Amendments • Cover crops • Mulching

  21. Natural Fertilizers • 2% Nitrogen • 6% Phosphorus • 3% Potassium • Calcium Magnesium Sulfur Manganese Zinc • Slow Release N • 4% Nitrogen • 6% Phosphorus • 4% Potassium • Calcium Magnesium Copper Sulfur • Slow release N 1 cup per full garden bed 1 cup per full garden bed

  22. Cover Crops:

  23. Mulching:
