  1. Plant Nutrition Floral Careers Plant Propagation

  2. Non-fertilizer Nutrients • Carbon (C), Hydrogen (H) and Oxygen (O). • These elements are supplied to the plant in the water and carbon dioxide it absorbs for photosynthesis. • All 3 are essential, non-fertilizermacroelements (or macronutrients).

  3. Macroelements • Macroelements are elements required by plants in relatively large quantities. • In addition to C, H, and O, 6 other elements are recognized as macroelements.

  4. Macroelements • They are: • Nitrogen (N) • Phosphorous (P) • Potassium (K) • Calcium (Ca) • Magnesium (Mg) • Sulfur (S)

  5. Microelements • Microelements are elements needed by plants in very small quantities. • Microelements are just as important as macroelements.

  6. Microelements • There are 8 essential microelements: • Iron (Fe) • Copper (Cu) • Zinc (Zn) • Manganese (Mn) • Boron (B) • Molybdenum (Mo) • Chlorine (Cl) • Nickel (Ni)

  9. Deficiency Symptoms of the Macroelements and Iron

  10. Nitrogen Deficiency • General chlorosis (yellowing) of the leaves. • Older leaves showing symptoms first. N deficiency in potato

  11. Phosphorous Deficiency • Reduced plant size • Darkened foliage with a purplish cast. P deficiency in corn

  12. Potassium Deficiency • Margins eventually turning brown. • Symptoms develop on lower leaves first. K deficiency on red currant

  13. Calcium Deficiency • Young leaves are prominently malformed. • Poor root development. Ca deficiency on sugar beet

  14. Magnesium Deficiency • Interveinal chlorosis. • Starts on the older leaves and progresses towards the top of the plant. Mg deficiency on grape

  15. Sulfur Deficiency • A chlorosis develops which affects the entire plant except the very tip. • Symptoms similar to a nitrogen deficiency.

  16. Iron Deficiency • Interveinal chlorosis developing on the youngest leaves first. • Damage confined to the upper regions of the plant. Fe deficiency on cherry
