PLANT NUTRIENT
DEFICIENCY
DEFICIENCY SYMPTOMS
• Nitrogen- Stunted growth, pale yellow
color, and burning of tips and leaf margins
• Phosphorus- Small root growth, spindly
stalk, delayed maturity, and purple
discoloring of leaves
• Potassium- Slow growth, scorched margins
on leaves, and shriveled seed or fruit
SYMPTOMS CON’T.
• Calcium- Terminal Bud dies, blossom shed
premature, and leave margins scalloped
• Magnesium- Yellowing of leaves between
veins, thin curved up leaves, and tissue may
dry and die
• Sulfur- Small spindly plants, light green
color, and delay in maturity
SYMPTOMS CON’T
• Boron- Death of terminal growth, “Witch’s
Broom Effect”, and thickened curled wilted
chlorotic leaves
• Copper- Stunted growth, poor
pigmentation, and death of leaf tip.
• Manganese- Interveinal chlorosis of young
leaves and no distinction between veins and
interveinal areas
SYMPTOMS CON’T
• Molybdenum- Stunting and lack of vigor
and marginal scorching cupping of leaves
• Zinc- Decrease in stem length and reduced
fruit bud formation
• Chlorine- Wilting, followed by chlorosis,
and excess branching of lateral roots
• Iron- Leaves yellowish or whitish and
affected leaves curl up
CAUSES OF SYMPTOMS
• Nutrient Availability- Sometimes nutrient
may be tied up in the soil due to being in a
form that the plant cannot use
• SOIL pH- Soil acidity or low pH reduces
the amount of some nutrients available to
the plant in the soil
