Terms in this set (34)
_________ are elements needed by a plant to promote healthy tissue, processes, and growth.
These are nutrients that plants need in large amounts:
Macronutrients include ________ primary elements and _____ secondary elementes.
Three primary nutrients are:
Nitrogen (N), Phosphorus (P) and Potassium (K).
Three secondary nutrients are:
Calcium (Ca), Magnesium (Mg) and Sulfur (S).
Three primary nutrients needed in the _________amounts
Nitrogen (N) Functions:
Promotes growth for leaves and stems.
Gives dark green color and improves quality of the foliage.
Is necessary to develop cell proteins and chlorophyll.
Nitrogen Deficiency symptoms
Sick yellow-green leaves.
Short stems, small leaves, pale colored leaves and flowers.
Slow and dwarfed plant growth.
Phosphorus (P) Functions
Stimulates early formation and growth of roots.
Provides for fast, vigorous growth and speeds maturity.
Stimulates flower and seed development.
Phosphorus (P) Deficiency symptoms
Decrease in growth.
Slow to maturity.
Older leaves are purplish color.
Potassium (K) Functions
Used to form carbohydrates and proteins.
Used in the formation and transfer of starches, sugars and oils.
Increases disease resistance, vigor and hardiness.
Potassium (K) Deficiency symptoms
Mottled, spotted streaked or curled leaves.
Scorched, burned dead leaf tips or margins.
Secondary nutrients are still needed in large amounts
Calcium (C) Functions
Improves plant vigor.
Influences intake and synthesis of other plant nutrients or elements.
Improve part of the cell walls.
Calcium (C) Deficiency symptoms
Small developing leaves and wrinkled older leaves are evident.
Dead stem tips are evident.
Magnesium (Mg) Functions
Influences the intake of other essential nutrients.
Helps make fats.
Assists in translocation of phosphorus and fats.
Magnesium (Mg) Deficiency symptoms
Interveinal chlorosis is the yellowing of leaves between green veins.
Leaf tips are curled and cupped upward.
Causes slender, weak stems.
Sulfur (S) Functions
Promotes root growth and vigorous vegetative growth.
Essential to protein formulation.
Sulfur (S) Deficiency symptoms
Young leaves are light green with lighter color veins
Leaves are yellow and stunted.
Micronutrients or trace elements are nutrients that plants need in very small amounts.
Iron (Fe) Functions
Is essential for chlorophyll production.
Helps to carry electrons to mix oxygen with other elements.
Iron (Fe) Deficiency symptoms
Mottled and interveinal chlorsis are found in young leaves.
Causes stunted growth and slender, short stems.
Copper (Cu) Functions
Helps with the use of iron.
Helps with respiration.
Copper (Cu) Deficiency symptoms
Young leaves are small and permanently wilted.
Multiple buds at stem tips.
Zinc (Z) Functions
Helps with the plant's metabolism.
Helps form growth hormones.
Helps with plant reproduction.
Zinc (Z) Deficiency symptoms
Slows growth between nodes.
New leaves are thick and small.
Spots between the veins and discolored veins.
Boron (B) Functions
It affects water absorption by the roots.
It translocates or moves sugars throughout the plant.
Boron (B) Deficiencies symptoms
It causes short, thick stem tips.
The young leaves of terminal buds are light green at the base.
The leaves become twisted and die.
Molybdenum (Mo) Functions
Is used for plant development.
Is used for reproduction.
Molybdenum (Mo) Deficiency symptoms
Stunted plant growth is evident.
It causes yellow leaves, upward curling leaves and leaf margin burn.
Manganese (Mn) Functions
It helps the plants metabolism.
It helps with nitrogen transformation.
Manganese (Mn) Deficiency symptoms
Interveinal chlorosis is evident.
The young leaves die.
Chlorine (C) Functions
Essential to some plant processes.
Acts in the enzyme system.
Chlorine (C) Deficiency symptoms
Usually there are more problems with too much chlorine or toxicity than with a deficiency.
Chlorine is found in the soil.
When plants are lacking in nutrients have a deficiency and may have a number of symptoms, including:
They will have a stunted appearance,
Pale green or yellow color (chlorosis) may develop initially, but coloring can be related to the nutrient that is lacking
A general appearance of being unhealthy.
Pale green or yellow color
