  • Transcript

    • 1. Mineral Nutrient Deficiencies and Toxicities Jim Owen, Jr. North Willamette Research and Extension Center
    • 2. Key to Nutrient Deficiencies
      • Base of plant – mobile (N, P, K, Mg)
      • Whole (mid) plant – partially mobile (S, Mo)
      • Top of plant – immobile (Ca, Fe, Mn, Zn, Cu, B)
        • Chlorosis (Mn, Fe)
          • Interveinal chlorosis with tan flecks (Mn)
          • Interveinal chlorosis – yellow - necrosis (Fe)
        • Necrosis & distortion (Ca, B)
    • 3. Mobile Nutrient – at base -N
    • 4. Immobile Nutrient – at top
    • 5. Partially Mobile – entire plant
    • 6. Mobile (at base) – N, P, K, Mg
      • Chlorosis is main early symptom
        • Uniform chlorosis
          • N or P
        • Interveinal
        • chlorosis
          • Mg
        • Rapid necrosis
          • K
      Maple
    • 7.
      • Uniform chlorosis then necrosis on older leaves
      • Stunting
      • Early flowering
      • Leaf abscission
      • Chlorosis then necrosis – old leaves
      • Severe stunting
      • Deep green foliage
      • Possible purpling
      • Roots longer & fewer
      Nitrogen vs. Phosphorus N P Uniform Chlorosis – lower leaves
    • 8. N Deficiency Symptoms
      • Uniform chlorosis of older leaves.
      • Necrosis of older leaves.
      • Abscission of older leaves if possible.
      • Red pigment - old leaves - some species
      • Earlier flowering with marginal N deficiency (later flowering if severe).
    • 9. Nitrogen deficiency uniform chlorosis of lower leaves -N Azalea
    • 10. Nitrogen deficiency stunting 0 5 10 20 40 60 grams of N applied in poly-coated urea Maple
    • 11. Uniform Chlorosis Followed by Necrosis Nitrogen Deficiency Tobacco here #2
    • 12. N Deficiency Early Flowering, Severe Stunting
    • 13. Nitrogen Deficiency Red Pigmentation on Older Leaves Blueberry Marigold
    • 14. Phosphorus Deficiency
        • Deeper green foliage.
        • Heavy stunting (compact form).
        • Purple (or red) pigmentation in several species.
        • Fewer & longer roots, more root mass at first, less when deficiency intense.
        • Lower leaf chlorosis  necrosis
    • 15. P Deficiency: deep green Chamaecyparis Impatiens
    • 16. Phosphate vs.Compactness P 2 O 5 as a % of N in post-plant fertilizer P 2 O 5 = 50% of N 15% 7.5% 0% (e.g. 20-10-20) (13-2-13)
    • 17. Phosphate vs.Compactness -P +P Thuja
    • 18. Phosphorus Deficiency longer but fewer roots
    • 19. lower leaf chlorosis Phosphorus Deficiency
    • 20. lower leaf necrosis Phosphorus Deficiency
    • 21. Nitrogen Toxicity
      • Wilting
      • Leaf desiccation
      • Root tip burn
      • Reduced uptake of K, Ca, Mg
    • 22. Ammonium Toxicity
      • Leaf desiccation
      • Bud necrosis
      • Root burn
      • Plant death
    • 23. Ammonium Toxicity Increasing Urea Rate (0 to 60 g)
    • 24. Older plant – pot mum Ammonium Toxicity lower leaf chlorosis & necrosis root tip death
    • 25. Magnesium - Mobile (symptoms originate at the base)
      • Interveinal chlorosis on older leaves
      • Necrosis of older leaves
      • Possible red on older leaves
    • 26. Magnesium - Mobile chlorosis (Maple) (Viburnum) (Chamaecyparis )
    • 27. Mg Deficiency Interveinal Chlorosis Older Leaves Dogwood Chrysanthemum
    • 28. Necrosis grape leaves Magnesium - Mobile
    • 29. Red Older Foliage Blueberry Magnesium - Mobile
    • 30. Potassium – Mobile (symptom originates on old leaves)
      • Chlorosis might occur briefly at tip and margin of old leaves.
      • Rapid necrosis of margins or spotting across old leaf blades.
      • Seedlings are often compact and deeper green prior to above symptoms.
    • 31. Potassium – Mobile Necrosis (Ginko) (Viburnum) (Maple)
    • 32. Necrotic Spotting poinsettia pepper K Deficiency
    • 33. Sulfur - Partially Mobile (symptoms originate throughout entire plant)
      • Uniform chlorosis on entire plant
