Learn how to meet the nutritional needs of plants by providing essential elements such as glucose, minerals, and suitable conditions. Discover the importance of proper mixtures, surface area, and recycling for optimal plant growth. Identify nutrient deficiencies and toxic build-ups in soil and how to address them effectively.
E N D
Nutritional Needs of plants • Food in form of sugar – used for energy • 2. Glucose, light, water, air, suitable temperature, minerals • 3. Food = energy minerals = healthy development • 4. Mixtures used for proper growth and development • 5. Increase surface area, increase absorption of water and minerals • 6. Evaporates out of leaf • 7. Deplete soil’s natural mineral supply • Recycle leaves and grass or add fertilizer • 8. Different concentrations of basic nutrients
9. Nitrogen, phosphorus, potassium • 10. 29 = % of N - nitrogen, • 3 = % of P- phosphorus, • 4 = % of K = potassium • 11. Healthy leaves • Not enough= light green leaves, thin stem too much = large leaves • but small flowers • 13. Healthy roots and flowers • tulips, newly planted trees • Leaves turn dark, purple/blue • 15. Survive dramatic temperature changes, protect • from disease • 16. Brown droopy leaves
Calcium, magnesium, sulfur, iron, boron, copper, chlorine, • manganese, molybdenum, zinc • 18. Poisonous mineral salts build up on roots • 19. Change amount of water added to fertilizer
