nutrients that plants need in large amounts
3 primary nutrients
are Nitrogen (N), Phosphorus (P) and Potassium (K).
Nitrogen - Functions
1) Promotes growth for leaves and stems.
2) Gives dark green color and improves quality of the foliage.
3) Is necessary to develop cell proteins and chlorophyll.
Nitrogen - Deficiency Symptoms
1) Sick yellow-green leaves.
2) Short stems, small leaves, pale colored leaves and flowers.
3) Slow and dwarfed plant growth.
Phosphorus - Functions
1) Stimulates early formation and growth of roots.
2) Provides for fast, vigorous growth and speeds maturity.
3) Stimulates flower and seed development.
Phosphorus - Deficiency Symptoms
1) Decrease in growth.
2) Slow to maturity.
3) Older leaves are purplish color
Potassium - Functions
1) Used to form carbohydrates and proteins.
2) Used in the formation and transfer of starches, sugars and oils.
3) Increases disease resistance, vigor and hardiness.
Potassium - Deficiency Symptoms
1) Mottled, spotted streaked or curled leaves.
2) Scorched, burned dead leaf tips or margins.
3 secondary nutrients
Calcium (Ca), Magnesium (Mg) and Sulfur (S).
Calcium - Functions
1) Improves plant vigor.
2) Influences intake and synthesis of other plant nutrients or elements.
3) Improve part of the cell walls.
Calcium - Deficiency Symptoms
1) Small developing leaves and wrinkled older leaves are evident.
2) Dead stem tips are evident.
Magnesium - Functions
1) Influences the intake of other essential nutrients.
2) Helps make fats.
3) Assists in translocation of phosphorus and fats.
Magnesium - Deficiency Symptoms
1) Interveinal chlorosis is the yellowing of leaves between green veins.
2) Leaf tips are curled and cupped upward.
3) Causes slender, weak stems.
Sulfur - Functions
1) Promotes root growth and vigorous vegetative growth.
2) Essential to protein formulation.
Sulfur - Deficiency Symptoms
1) Young leaves are light green with lighter color veins
2) Leaves are yellow and stunted
nutrients that plants need in very small amounts
Iron - Functions
1) Is essential for chlorophyll production.
2) Helps to carry electrons to mix oxygen with other elements.
Iron - Deficiency Symptoms
1) Mottled and interveinal chlorsis are found in young leaves.
2) Causes stunted growth and slender, short stems.
Copper - Functions
1) Helps with the use of iron.
2) Helps with respiration.
Copper - Deficiency Symptoms
1) Young leaves are small and permanently wilted.
2) Multiple buds at stem tips.
Zinc - Functions
1) Helps with the plant's metabolism.
2) Helps form growth hormones.
3) Helps with plant reproduction.
Zinc - Deficiency Symptoms
1) Slows growth between nodes.
2) New leaves are thick and small.
3) Spots between the veins and discolored veins.
Boron - Functions
1) It affects water absorption by the roots.
2) It translocates or moves sugars throughout the plant.
Boron - Deficiency Symptoms
1) It causes short, thick stem tips.
2) The young leaves of terminal buds are light green at the base.
3) The leaves become twisted and die.
Molybdenum - Functions
1) Is used for plant development.
2) Is used for reproduction
Molybdenum - Deficiency Symptoms
1) Stunted plant growth is evident.
2) It causes yellow leaves, upward curling leaves and leaf margin burn.
Manganese - Functions
1) It helps the plants metabolism.
2) It helps with nitrogen transformation
Manganese - Deficiency Symptoms
1) Interveinal chlorosis is evident.
2) The young leaves die
Chlorine - Functions
1) Essential to some plant processes.
2) Acts in the enzyme system.
Chlorine - Deficiency Symptoms
1) Usually there are more problems with too much chlorine or toxicity than with a deficiency.
2) Chlorine is found in the soil.
