Plant Nutrients

1
Plant Nutrients

• Plant nutrients are divided into three main
  categories
• Primary nutrients
• Secondary nutrients
• Micronutrients

2
Primary Nutrients

• Primary nutrients are needed by the plant in
  large quantities.
• There are six nutrients in this category
• - Carbon (C) - Phosphorus (P)
• - Hydrogen (H) - Nitrogen (N)
• - Oxygen (O) - Potassium (K)

3
Secondary Nutrients

• Secondary nutrients are needed in quantities
  which are lower than primary, but greater than
  micronutrients. These nutrients are
• - Sulfur (S) - Iron (Fe)
• - Calcium (Ca) - Magnesium (Mg)

4
Micronutrients

• Micronutrients are needed in very small amounts,
  and are the greatest in number.
• - Molybdenum (Mo) - Zinc (Zn)
• - Boron (B) - Chlorine (Cl)
• - Copper (Cu) - Manganese (Mn)

5
Nitrogen (N)

• Function
• Promotes rapid vegetative growth.
• Gives the plant a healthy green color.

• Deficiency Symptoms
• Stunted growth.
• Pale yellowish color.
• Burning of tip margins on leaves.

6
Phosphorus (P)

• Functions
• Stimulates early growth and root formation.
• Promotes seed growth.
• Hastens maturity.
• Makes plants hardy.

• Deficiency Symptoms
• Small growth.
• Spindly stalk.
• Delayed maturity.
• Purplish color of leaves.
• Dying of tips of older leaves.
• Poor fruit and seed development.

7
Potassium (K)

• Functions
• Improves plants ability to resist disease and
  cold.
• Aids in production of carbohydrates.

• Deficiency Symptoms
• Slow growth.
• Margins of older leaves appear scorched.
• Weak stalk.
• Shriveled fruit or seed.
