4. To grow healthy crops full of nutrients, farmers need
to ensure they have healthy soil. Without fertilizers,
nature struggles to replenish the nutrients in the soil.
A balanced nutrient supply from the soil is the
foundation to help large populations avoid nutrient
deficiency related health problems.

6. INTRODUCATION

Fertilization increases efficiency and obtains better
quality of product recovery in agricultural activities.
It is one of the most important ways. Non
fertilizers mainly contain phosphate, nitrate,
ammonium and potassium sa
considered to be source of natural radionuclides and
heavy metals as a potential source. It contains a large
majority of the heavy metals like Hg, Cd, As, Pb, Cu, Ni,
and Cu; natural radion

Fertilization may affect the accumulation of heavy metals
in soil and plant system. Plants absorb the fertilizers
through the soil, they can enter the food chain. Thus,
fertilization leads to water, soil and air pollution

7. AIM

The goal of research on fertilizer rate is to
determine the amount of fertilizer needed to
achieve a commercial crop yield with sufficient
quality that is economically acceptable for the
grower

8. THEORY

A fertilizer is that substance which is used to make soil
more fertile such as manure or a mixture of nitrates. It
is applied to the soils or to plant tissues to supply one
or more plant nutrients essential to the growth of plants.
Hence, we can say in other words that the fertilizers are
the chemical substances which are directly respondent
for the substantial growth of the plants or crops and
being supply the nutrients in the form of nitrogen,
phosphorus, potassium etc and keep the soils fertile.
The goal of research on fertilizer rate is to determine
the amount of fertilizer needed to achieve a commercial
crop yield with sufficient quality that is economically
acceptable for the grower.
Fertilizers enhance the growth of plants. This goal is
met in two ways, the traditional one being additives
that provide nutrients. The second mode by which
some fertilizers act is to enhance the effectiveness of
the soil by modifying its water retention and aeration

9. ClASSIFICATION OF FERTIlIZERS

The fertilizers are classified on the basis of the
nature of nutrient elements like Nitrogen,
phosphorus, potassium (NPK) present chemically
in the compounds. There are various nitrogenous
chemical fertilizers like ammonium sulphate,
calcium ammonium nitrate, basic calcium nitrate,
calcium cyanamide (nitrolium), urea etc. Obviously
these fertilizers supply nitrogen to the soil.
Similarly there are various phosphatic chemical
fertilizers like super phosphate of lime, triple super
phosphate etc and potash chemical fertilizers like
potassium chloride, potassium nitrate, potassium
sulphate etc. Thus phosphatic and potash chemical
fertilizers supply phosphorus and potassium to the
soil respectively.

There are also some chemical fertilizers of
different composition like that of nitrogen
phosphorus (NP) fertilizers in which nitrogenous
and phosphatic fertilizers are mixed up in a
definite and proper ratio.

10. The fertilizers like dehydrogenate ammoniated
phosphate, calcium super phosphate etc are NP
fertilizers. Sometimes NPK fertilizers are composed
to supply nitrogen, phosphorus and potassium
simultaneously to the soil

nitrate by the denitrifying bacteria present in the
alkaline soil. Thus these nitrates are easily
absorbed by the crops and plants. This fertilizer is
produced in India at large sca
Jharkhand.

of nitrogen is about 20 which is directly
absorbed by the plants. On mixing it

 FARMER & GARDENERS : The benefit of this
study will help them to improve the quality of their
product , save time with their work and get a .
higher profit.

 ENVIRONMENT : This study will help our
environment by helping the soil and plant to
sustain their needs and provide the essential
nutrients required for optimum growth.

 AGRO COMPAN :This study will help them to
give a good service to their customer by giving
them a high and good quality product.
( Rice ,Wheat , vegetable & fruits )


 COMMUNITY: It helf the community to sense
this as a source of income if made into a business.

16. CONClUSION

 ADVANTAGES OF FERTIlISER

 It increases crop yield and improves
poor quality land.

 Manure improves soil texture, recycles
nitrogen and introduces essential
bacteria.

 Pasture is improved so animals fatten
up quicker.

 Once marshland is drained, fertilisers
can help reclaim that land for pasture.

 Crops grow faster – particularly when
hybrid seeds are used.

17.  DISADVANTAGES OF FERTIlISER

 Fertilisers are costly.

 Continuous use of fertilizers in an area
can destroy soil fertility because the
organic matter in the soil is not
replenished.

 Their addition can have harmful effects
on the soil such as soil acidification,
persistence of toxic organic compounds
and accumulation.

 The use of fertilizers on a global scale
emits significant quantities of
greenhouse gas into the atmosphere.
