Composition of soil
What does organic matter do in soil?
 OM is most important component of soil
 OM serve as
reservoir of nutrients
 water in soil
Help in reducing compaction
Reduce surface crusting
Increases water infiltration into the soil
Benefits of OM
 Improve the soils ability to take up and hold
water
 Improve the soil structure
 work like a sponge that absorb up to 90
percent water
 release most of the water that is absorbs to
water
 Release nutrients in soil that increases its
fertality
OM provides

Nutrients
 chemical
substance found in
food
Which help the
body work
Maintain the body
balance
Provide
nourishment for
growth
We need 50
nutrients overall
That divided into
six groups
Why you need nutrients?
Your body need nutrients to
 Fuel your body
 Help you to grow
 Repair yourself
 Maintain basic bodily functions
 Such as metabolism, growth and sexcual
functions etc.

Types of nutrients
Role Of 6 Major Nutrients
 Water (remove waste nutrients and regulate body
temperature)
 Protein (build new tissues, antibodies, enzymes and
hormones etc)
 Carbohydrate (provide energy)
 Fat (provide long term energy, insulation and
protection)
 Vitamins (facilitate use of other nutrients, regulate
growth and manufacturing hormones)
 Minerals (build bones and teeth, help in muscle
functioning and nervous system activity)

Macronutrients
And
Micronutrients
 Macronutrients
1) Nutrients that required in
large amount
2) E.g Protein, fiber, water
and carbohydrates
3) Cereals, legumes, meat,
fish, yams, potatoes, nuts,
oil and seeds are rich in
macronutrients
4) Provide bulk energy
needed for metabolic
system
 Micronutrients
1. Nutrients that require in
small amount
2. E.g photo chemicals,
antioxidants, vitamins and
certain minerals
3. Vegetables, fruits, eggs,
green, leafy vegetables
etc. are rich in
micronutrients
4. Help various functions of
the body, growth and
prevent diseases
Micronutrients
 Outlines
 Definition
 Introduction
 Source
 Importance
 Deficiency effect
Definition
 Essential elements required by organisms
 In varying quantity
 To orchestrate a range of physiological
functions
 And maintain health
 Their requirement differ between organisms
 E.g humans and other organisms require
numerous vitamins and dietary minerals
 But plants require specific nutrients.
Role of micronutrients
 Micronutrients play a central role in
metabolism and in maintenance of tissue
functions
 Vitamins and minerals are basic
micronutrients
Soil organic matter, Nutrients and Micronutrients, Pesticides effects
Essential nutrients
for plants
 7 nutrients essential for plant growth and health
 Needed in small quantity but very necessary
 Boron (regulate metabolism, transport
carbohydrate )
 Chlorine (necessary for osmosis, photosynthesis)
 Copper (work like enzymes)
 Iron (essential for chlorophyll synthesis)
 Manganesa (activate enzymes)
 Molybdenum (essential for plant health)
 Zinc (activate enzyme, chlorophll formation)
Essential nutrients
for humans
 Minerals and vitamins
 Require through out the life
 But in small quantity
 Nutrients (chromium, cobalt, copper, iodine,
iron, manganesa, molybdenum, selenium,
zinc)
 Vitamins (vitamin B complex B1, B2, B3, B5,
B6, B7, B9,B12, A, C, D, K)
VITAMINS
MINERALS
TYPE OF VITAMINS
 Water soluble (vitamin B group)
__ Dissolve easily in water
__ and excreted from the body
 Fat soluble (A, D, E and K)
__ absorbed through the intestinal tract
__ with the help of lipids (fats)
Function
of vitamins
 Acts as hormones
 Act as antioxidant
 Act as mediators
 Regulate cells and tissues growth
 Act as enzyme cofactor
 Act as a catalysts
Function
of minerals
 Ca __ play role in formation of bones
 Mg__ act as cofactor of enzyme
 Fe__ transportation of oxygen
 K__ regulate heart beat
 Zn__ boost body immunity and heal wounds
 Cl __ produce acid in stomach
 I __ produce thyroid hormones
 P __ synthesis DNA and bones
 Na __ balance pH
 Cu __ metabolize iron and enzymes
 Se __ functioning antioxidant enzymes
