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