It's an presentation slide of Mixed & complex Fertilizer. I also discuss about alternative way to subside the use of mixed and complex fertilizer.

2. As love is the fertilizer for the soul of
two loving people.
just like
Plants need fertilizer to
development their own souls also.

01 About Fertilizer

5. A fertilizer is any material of natural or synthetic origin that is applied to soils or to
plant tissues to supply one or more plant nutrients essential to the growth of plants.
specifically : a substance (such as manure or a chemical mixture) used to make soil
more fertile.
Fertilizer
There are 5 types of fertilizer according to nutrients present :
1. Straight fertilizer 2. Complex fertilizer 3. Mixed fertilizer
4. Bio fertilizer 5. Compound fertilizer

6. MIXED FERTILIZER

7. What does Mixed Fertilizer mean ?
Mixed fertilizer means a fertilizer containing any combination or mixture of
straight fertilizer materials designed for use or claimed to have value in
promoting plant growth, including mixtures of fertilizer and pesticide. They
are slow releasing by nature and remain in the field for a long time.

8. Open formula mixed fertilizer Closed formula mixed fertilizer
In this case, the
manufacturing firms disclose
the names and quantities of
the straight fertilizers that are
constituents of the mixed
fertilizer.
In this case, the
manufacturing firms do not
disclose the names and
quantities of the straight
fertilizers that are constituents
of the mixed fertilizer.
Kinds of Mixed
Fertilizer

9. Main Advantages
Much labor
doesn’t need
Less labor is required
to apply a mixture
than to apply its
components
separately
Mixture have better
physical condition
Due to better physical
condition they are slow
releasing by nature and
remain in the field for a
long time. They are
tailor made as per the
soil and are crop
specific.
Easily
incorporated
Micronutrients
can be easily
incorporated in
fertilizer mixture.
Balanced manuring
Use of fertilizer
mixture leads to
balanced manuring

10.  Use does not permit individual
nutrient application which of
specific growth stage of crop.
 Unit cost of plant nutrients in
mixtures is usually higher than
those of straight fertilizers.
 Farmers use mixtures without
careful study of their needs.
 The firms charge for mixing the
fertilizers.
Disadvantages

11. Manufacturing process of Mixed Fertilizer
Equipment's for
packing fertilizer
mixture range from
the simplest types of
hand operated
facilities to highly
sophisticated
automatic machines.
CALCULATING AND
WEIGHING
SIEVING AND SIZING MIXING PACKING
With a good weighing
device the calculated
quantities of the
various ingredients
are weighed
accurately for
preparing mixtures.
The raw materials must
be converted into
uniform sized particles
to have effective making
and to avoid segregation
during subsequent
handling.
Weighed quantities of
different materials are
introduced into the
Rotary drum, vertical
cylinder and mixed
thoroughly.

12. CHEMICAL & PHYSICAL CHANGES THAT
OCCURS WHILE MANUFACTURING
Segregation
It is a property of any substance which absorbs
moisture from air and gets converted to semi- solid or
liquid condition. Fertilizer like Ca(NO3)2, NH4NO2 are
capable of absorbing moisture from air and become
hygroscopic. This relates to separation of
different sized particles
individually. When ingredients of
different sizes and densities are
included there will be the tendency
for the segregation (sorting out to
different sizes) to take place.
HYGROSCOPICITY
Caking up
Moisture present in some of the ingredients
is responsible for caking up. Moisture
dissolves some of the easily soluble
ingredients and forms a saturated solution.
This saturated solution on evaporation gives
out crystals which knit together forming
larger lumps.

13. Complex FERTILIZER

14. COMPLEX FERTILIZER
TYPES OF COMPLEX FERTILIZERS
Complex fertilizers is defined as a
material containing all three primary,
nutrients ( N,P and K) and it is also
designated as complete complex
fertilizers while a fertilizer material
containing one or two of the primary
nutrient elements (N and P or P and K
etc) are known as incomplete complex
fertilizers. They are produced by a
process of chemical reaction.
•NPK 20.20.0
•NPK 27.13,5.0
•NPK 22.22.0
•NPK 15.15.15
•NPK 20.10.10
•NPK 16.20.0
•DAP 18.46.0
•MAP 12.52.0
Definition

15.  Complex fertilizers come as granules of different colors according to the
assortment
They are less hygroscopic
Their role is to neutralize the physiological acidity
They have a higher ratio of using the nutrients
They do not leave residues in the soil
CHARACTERISTICS OF COMPLEX FERTILIZERS

16. NPK FERTILIZER
Method of
manufacture
NPK fertilizer is a complex fertilizer comprised
primarily of the three primary nutrients required
for healthy plant growth.
 Granulation with a pipe reactor system
 Nitro phosphate Route
 Mixed Acid Route

23. Use of fly ash
USE OF CHARCOAL
USE OF COMPOST
Alternative way to subside the use of mixed
and complex fertilizer

24. Use of Charcoal
Charcoal is a lightweight black carbon residue produced by removing water and
other volatile constituents from animal and plant materials.
Charcoal addition significantly increased biomass production of rice crop.
IMPORTANCE
Improve the potassium and phosphorus availability for plant
nutrient
The combine application of N with charcoal resulted in a higher N
uptake for plant

25. Use of Compost
Compost is made up of organic materials that break down in the soil, enriching its
structure and adding essential nutrients
COMPOST
wooded areas are filled with organic materials—trees, leaves, etc. Over time these
materials slowly decompose, or break down, with the help of micro-organisms
and earthworms. Once the materials have decomposed, they turn into humas, an
essential element in the production of rich, fertile soil that is also responsible for
producing healthy plants.
IMPORTANCE
It can enhance the soil, building up the structure and texture.
It increases airflow and water retention.
Compost also stabilizes pH levels and supports essential bacteria.

26. FLY ASH
COAL COMBUSTION RESIDUE OF thermal power plants known as fly ash also
known as problematic solid waste.
The disposal of high amount fly ash from thermal power plant absorbs huge
amount of water & energy.
IMPORTANCE
 Improve the physical, chemical& biological properties of degrade soil
 Modification of soil health & crop performances.
 High concentration of elements(k,Na,Zn,Ca,Mg &Fe) in flyash increases the yield
of many agricultural crops
 1:1 ratio (coal:flyash) increases the adsorption sites available for plant nutrients.
USE OF FLY ASH
