YOUR FERTILIZATION PROGRAM

by Jack Wright

This was a presentation at the Carolina District Workshop on February 1, 1998 in Charlotte, North Carolina.


KNOW YOUR SOIL

There are 16 elements essential to all plant growth. Without any one of them, plant growth will not occur, even if the other elements are present in their required amounts.

 
The first three (3) elements are derived primarily from the atmosphere and water, and they are:

    1. Carbon
    2. Hydrogen
    3. Oxygen

The remaining 13 elements are absorbed by the plant roots from the surrounding soil. they must either be available in the soil in their natural form, or they must be supplied by application to the soil.

They are broken down into three (3) categories as follows:

Most Essential to Plant Growth

4. Nitrogen

5. Phosphorous

6. Potash

Essential to Plant Growth, In Slightly Lesser Amounts

7. Calcium

8. Magnesium

9. Sulfur

Essential to Plant Growth in Very Small Amounts

10. Boron

11. Chlorine

12. Copper

13. Iron

14. Manganese

15. Molybdenum

16. Zinc

Minerals & Trace Elements

Comments

Alfalfa Meal

3

1

2

Rich in minerals and trace elements. Contains triconatol, a growth stimulant valuable to roses.

Analysis varies with crop quality, but alfalfa is a great soil builder and increases the micro-organisms in the soil. 200 cups per 50 lb bag (4 oz/cup)

Bat Guano

3

8

1

Supplies 24 trace elements

One of the best all-around organics.

Blood Meal

0.7

 

Source of readily available nitrogen.

Bone Meal

0

Analysis may vary.

Excellent source of phosphorous; lasts 6 to 12 months; raises pH.

Cottonseed Meal

7

2

2

 

Excellent where low pH is not a problem. 133 cups per 50 lb bag (6 oz/cup)

Fish Emulsion

5

Apply to the soil and also as a foliar spray.

Fish Meal

2

 

Excellent year round fertilizer; apply anytime roses need a boost. 133 cups per 50 lb bag (6 oz/cup)

Greensand

0

1

7

18% iron oxide; and 30 other trace elements.

Slowly available; loosens soils.

Kelp Meal

1

0

8

33% trace minerals; includes more than 50 minerals.

Great stuff, but expensive.

Leather Tankage

10

0

0

 

2% nitrogen immediately available; remainder releases slowly -- does not burn or leach.

Rock Phosphate

0

16

0

27% calcium

Lasts for years; apply with compost for better availability.

Seaweed (Liquide)

1

0

4

Excellent source of trace minerals; high in amino acids.

A great foliar feed. Improves leaf and blossom color.
