Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle. Plant nutrients are the chemical elements that are essential to the nourishment of plant health. Each plant nutrient performs a crucial role in plant growth and development. Primary nutrients : are also known as macronutrients and are the ones that are needed the most. Carbon, phosphorus, oxygen, nitrogen, hydrogen and potassium are the elements. Secondary nutrients : are required at fewer levels than primary essential nutrients. Calcium, magnesium, and sulphur are the elements. Micro or trace nutrients : are only necessary for trace amounts compared to primary or secondary nutrients. Boron, chlorine, copper, iron, manganese, molybdenum and zinc. Nitrogen : By impacting the plant’s leaf development, nitrate (the type of nitrogen used by plants) aids in the growth of strong foliage. It also contributes to the green hue of plants by assisting in the formation of chlorophyll. Phosphorus : Phosphorus is a mineral that aids in the development of roots and blooms. Phosphorus also aids in the resistance of plants to environmental stress and hard winters. Potassium :Potassium boosts plants, aids early growth, and aids water retention. It also affects disease and pest resistance in the plant. Sulphur :Sulphur aids plant disease resistance while also aiding plant growth and seed development. Vitamins, enzymes, proteins, and amino acids, are all produced with their help. Calcium :  Calcium is necessary for cell wall formation and development because strong cell walls aid the plant’s resistance to disease. It’s also required for the plant’s metabolism and nitrogen uptake. Magnesium :Magnesium acts as a phosphorus carrier in plants and is essential for phosphate metabolism. Furthermore, it is also needed for cell division and protein formation, activation of several enzyme systems and is an essential component for plant respiration. Zinc : activates enzymes that are responsible for the synthesis of certain proteins and excess zinc compete with plant uptake of phosphorus, iron, manganese or copper. Boron : used with Ca in cell synthesis and essential for cell division, pollination and seed development, helps to transport sugar, tissue development. Iron : maintenance and synthesis of chlorophyll and RNA metabolism, increases the thickness of the leaf, photosynthesis, N2 fixation and respiration. Manganese : resistance against diseases, activating over 35 enzymes and tolerance to different environmental stress. Balanced fertilizer use refers to application of essential plant nutrients in optimum qualities and in right proportional through appropriate method and time of application suited for a specific crop and agronomic situation. Balanced fertilizer rates differ from area and also from crop to crop.Soil testing is one of the most important

2. PLANT NUTRIENTS
• Plant nutrition is the study of the chemical
elements and compounds necessary for plant growth and
reproduction, plant metabolism and their external supply.
In its absence the plant is unable to complete a normal
life cycle.
• Plant nutrients are the chemical elements that are
essential to the nourishment of plant health.
• Each plant nutrient performs a crucial role in plant
growth and development.

3. TYPES OF NUTRIENTS
• Primary nutrients : are also known as macronutrients
and are the ones that are needed the most. Carbon,
phosphorus, oxygen, nitrogen, hydrogen and potassium
are the elements.
• Secondary nutrients : are required at fewer levels than
primary essential nutrients. Calcium, magnesium, and
sulphur are the elements.
• Micro or trace nutrients : are only necessary for trace
amounts compared to primary or secondary nutrients.
Boron, chlorine, copper, iron, manganese, molybdenum
and zinc.

4. PRIMARY NUTRIENTS
• Nitrogen : By impacting the plant’s leaf development,
nitrate (the type of nitrogen used by plants) aids in the
growth of strong foliage. It also contributes to the
green hue of plants by assisting in the formation of
chlorophyll.
• Phosphorus : Phosphorus is a mineral that aids in the
development of roots and blooms. Phosphorus also aids
in the resistance of plants to environmental stress and
hard winters.
• Potassium :Potassium boosts plants, aids early growth,
and aids water retention. It also affects disease and pest
resistance in the plant.

5. SECONDARY NUTRIENTS
• Sulphur :Sulphur aids plant disease resistance while also
aiding plant growth and seed development. Vitamins,
enzymes, proteins, and amino acids, are all produced with
their help.
• Calcium : Calcium is necessary for cell wall formation and
development because strong cell walls aid the plant’s
resistance to disease. It’s also required for the plant’s
metabolism and nitrogen uptake.
• Magnesium :Magnesium acts as a phosphorus carrier in
plants and is essential for phosphate metabolism.
Furthermore, it is also needed for cell division and protein
formation, activation of several enzyme systems and is an
essential component for plant respiration.

6. MICRO OR TRACE
NUTRIENTS
• Zinc : activates enzymes that are responsible for the
synthesis of certain proteins and excess zinc compete
with plant uptake of phosphorus, iron, manganese or
copper.
• Boron : used with Ca in cell synthesis and essential for
cell division, pollination and seed development, helps to
transport sugar, tissue development.
• Iron : maintenance and synthesis of chlorophyll and
RNA metabolism, increases the thickness of the leaf,
photosynthesis, N2 fixation and respiration.
• Manganese : resistance against diseases, activating over
35 enzymes and tolerance to different environmental
stress.

8. BALANCED NUTRITION
• Balanced fertilizer use refers to application of
essential plant nutrients in optimum qualities and in
right proportional through appropriate method and
time of application suited for a specific crop and
agronomic situation.
• Balanced fertilizer rates differ from area and also from
crop to crop. Soil testing is one of the most important
tools to practice balanced fertilization.

9. AIMS OF BALANCED FERTILIZATION
• Increasing crop yield
• Improving quality of the produce
• Increasing farm income
• Correction of soil nutrient deficiencies
• Improving soil fertility
• Reduces environmental hazards

10. 4 ‘R’PRINCIPLE IN BALANCED
NUTRITION :
• Right product :
• (a)matches fertilizers type to crop needs.
• (b)Different crop species have different nutrient
requirements and there is wide range of
fertilizers with different profiles to meet these.
Product selection takes into account the needs of
a particular crop, climate amd soil properties,
economic considerations and method of
application

11. • Right rate :
• (a) Matches amount of fertilizers type crop needs.
• (b) Understanding the nutrient needs of a crop
throughout its growth cycle is the first step to
calculating a suitable fertilizer application rate.
• (c) An excess of nutrients will lead to
environmental losses, while an insufficiency will
limit crop yield.

12. • Right time :
• (a) makes nutrients available
when crops needs them.
• (b) for optimum yields, sufficient nutrients need to
be accessible to a crop as it moves through its
various growth stages. But if a nutrient is present in
the soil for an extended period prior to crop uptake,
it may move outside the root zone or be converted
into a less plant-available form.
• (c) the best timing for fertilizer application is
therefore based on consideration of the timing of
crop uptake, the dynamics of the soil nutrient supply
and the release rates of specific products.

13. • Right place :
• (a) Keep nutrients where
crops can use them.
• (b) A plant’s full genetic potential is only
achieved when the soil structure allows its roots
to grow and exploit the maximum soil volume.
• (c) A good soil structure ensures the right
proportion of voids of different sizes for good
rooting conditions and improves the roots
ability to locate nutrients.
• (d) With nutrients in the right location within
the soil, crops have the best access to them.
