• W H A T I S T H E SOIL?
• The soil is the uppermost part of the earths
  surface that supports plant growth.
• Everything we use comes directly or indirectly
  from the soil, except the air that we breathe and
  sunlight.

3
WHAT DOES THE SOIL PROVIDES?

• The soil provides
• Root Room
• Anchorage
• Storage
• Food (Nutrients)

4
WHAT MAKES UP THE SOIL?

• The soil is composed of the following
• Sand
• Silt
• Clay
• Organic Matter
• Water
• Insects
• Fungi
• Air
• Rocks
• Bacteria
• Animals (Small)

5
SOIL PROFILE

• Majority of feeder roots are in the upper 8-10
  of the soil, therefore the amount of sand, silt
  or clay that is present, will influence how we
  manage the soil.

6
WHAT DOES COFFEE PLANTS NEED TO GROW?

• Water
• Light
• Air Atmosphere/soil
• Nutrients
• HOW ARE THESE RELATED?

7
WHAT DOES COFFEE PLANTS NEED TO GROW? CONTD
8
WHAT IS SOIL FERTILITY?

• The amount of plant food that is available for
  growth and development of plants.
• It is, therefore, very important to find out the
  amount of plant food that is in the soil before
  we add more to it.
• Why?
• We may be putting too much of one type and not
  enough of others which are lacking.

9
FERTILIZER

• A fertilizer is a concentrated source of plant
  nutrient which can be derived from organic or
  in-organic material.
• Popular ones for coffee are
• 15 5 35
• 16 9 18
• 23 10 20
• UREA
• AMMONIUM SULPHATE
• FOWL MANURE

10
WHAT DO FERTILIZERS PROVIDE?
11
WHEN DO WE FERTILIZER?

• After reaping
• Before flowering
• After fruit set
• During reaping

12
WHEN DO WE FERTILIZER? CONTD

• WHY DO WE FERTILIZE?
• 1. To maintain good foliage
• 2. To promote growth
• 3. To promote flowering
• 4. To promote root development
• 5. To replace lost nutrients
• 6. To repair and strengthen damaged tissues
• 7. To enhance fruit growth and development

13
HOW DO WE FERTILIZE?

• BROADCAST
• PLACEMENT
• Sub-surface/Surface
• Drip Circle
• Semi Circle
• FOLIAR
• FERTIGATION

14
HOW MUCH DO WE APPLY?

• THE AMOUNT WE APPLY DEPENDS ON
• Nutrient status of the soil
• Condition of the plant
• Age of the plant
• Stage of development
• Targeted yield
• Plant population

15
HOW MUCH DO WE APPLY? CONTD

• For mature producing trees, the general
  recommendations are
• 1 to 2 lbs N- P K/ Plant per Year
• 8 ounces Urea/ Plant per Year
• OR
• 1lb Amsul per Plant /Year

16
COFFEE TREES NEED

• Adequate fertilizer to be strong and healthy
• To maintain vigorous production of new growth
• To achieve the maximum yield potential in them
  and
• To recover as soon as possible after harvesting
  and pruning operations.
