Plant Nutrition Vs Plant Fertilization
  • Nutrition
  • Availability and type of chemical
  • elements
  • in plant
  • Fertilization
  • Adding nutrients to soil

4
Nutrients
  • 16 elements
  • C, H, O,
  • Macronutrients
  • Micronutrients

5
Macronutrients
  • Nutrients required in large quantities
  • N
  • P
  • K
  • Ca
  • Mg
  • S

6
Primary Nutrients
  • N
  • P
  • K
  • Primary because they are
  • needed in large amounts

7
Secondary Macronutrients
  • Ca
  • Mg
  • S
  • Only moderate amounts required

8
Micronutrients(Nutrients needed in small
quantities)
  • Mo
  • Na
  • Zn
  • B
  • Cu
  • Cl
  • Fe
  • Mn

9
How to Remember????
  • C HOPKNS Ca Fe Mg
  • (C. Hopkins café might good)
  • Remaining nutrients
  • B, Cu, Cl, Mn, Mo, Zn

10
What are the role of nutrients?
(refer to handout)
11
What makes plants look Unhealthy?
  • Discoloration of leaves
  • Death of leaf tissue
  • Stunted growth

12
Examples
  • Discoloration
  • of
  • Leaves

13
Nutrient Deficiencies
  • N
  • Chlorosis on
  • lower leaves

14
Nutrient Deficiencies
  • N
  • Chlorosis of
  • leaves

15
Nutrient Deficiencies
  • P
  • Purplish
  • coloration
  • of leaves

16
Nutrient Deficiencies
  • K
  • Chlorosis
  • of leaves
  • Brown leaf edges

17
Nutrient Deficiencies
  • K
  • Chlorosis
  • of leaves
  • Brown leaf edges

18
Nutrient Deficiencies
S yellowing of entire plant leaves
19
How can you correct nutrient deficiency?
20
Fertilizer
21
What is fertilizer?
  • Any material added to the soil to
  • provide nutrients that will increase
  • growth, yield, or nutritional value of
  • the plants.

22
Fert. Classifications
  • Inorganic
  • Natural Organic
  • Synthetic Organic

23
Inorganic Fert.
  • Non-living sources (minerals/rocks)
  • Chemically made

24
Inorganic Fert.
  • Characteristics
  • Nutrients in soluble form
  • and quickly made available to plants
  • Should not come in contact with roots
  • or foliage for long time period

25
Natural Organic
  • From plant/animal material
  • Characteristics
  • N usually predominant
  • Nutrients are only made available to the
    plants as the materials decay in soil, so SLOW
    ACTING LONG LASTING

26
Natural Organic
  • Examples
  • Animal manure
  • Cottonseed meal
  • Soybean meal
  • Dried blood
  • Dried ground/sewage sludge
  • Bone meal

27
Synthetic Organic Fert.
  • Made from carbon based materials
