Fertilizer They are materials that contain one
or more of the essential elements(N, P K either
single or in combination) and are applied to
soils to encourage crop growth.

• Bio Fertilizer
• It is a Natural organic fertilizer known that
  helps to provide all the nutrients required by
  the plants and helps to increase the quality of
  the soil with a natural Living micro-organism
  environment.

TYPES OF BIO - FERTILIZER

• Normally, Bio Fertilizers are divided into two
  types.

1. Manure They are biologically
   originated and obtained from animal excreted
   kitchen waste, agricultural waste and green
   plants. The are highly nutritious and improve
   the quality or soil. They are a) Compost
   Manure, b) Farmyard Manure c)
   Green Manure.

1. Compost Manure These type of
   manures are prepared from waste released from
   household activities, which are kept within a pit
   for about 8 9 months. After that period it acts
   as a fertilizer.
2. Farmyard Manure These type of
   manures are prepared from solid or liquid excreta
   released from animals husbandry as well as from
   agricultural waste. These substances were
   deposited at same places about 5 -6 months. After
   that period it acts as a fertilizer.

Plants that are used in Green Manures are as
follows
c) Green Manure These are the green plants
which are grown in the agricultural field and
plough under the field. After one to two months,
it acts as a fertilizer. It is practically
verified that by the uses of green manures, the
productivity of field increases by 40.

• Alexandrium trifoliumAlexandrium repens
• Serbania rortzataSerbania aculata
• (Dhahincha)

Significance of Manure (Green Manure)

• It helps to increase the productivity of soil by
  40.

• It helps to make the soil fertile.

• It helps the percolation capacity of soil.

• It helps to prevent from involution.

• It helps to increase water holding capacity of
  soil.

• It helps to prevent from soil erosion.

1. Biological Fertilizer They are originated
   from alive living organisms. They are
   cyanobacteria and Fungi.

WORKING OF BIO - FERTILIZER

• Bio fertilizers fix atmospheric nitrogen in the
  soil and root nodules of legume crops and makes
  it available to the plant.

• They solublises the insoluble forms of phosphates
  like tri-calcium, iron and aluminum phosphates
  into available forms.

• They decompose organic matter and help in
  mineralization in soil.

• They scavenge phosphate from soil layers..

• They produce hormones and anti metabolites which
  promote root growth..

• They produce hormones and anti metabolites which
  promote root growth.

• When applied to seed or soil. Bio fertilizers
  increase the availability of nutrients and
  improve the yield by 10 to 25 without adversely
  affecting the soil and environment.

BENIFITS FROM USING BIO - FERTILIZER

• Increase crop yield by 20-30.

• Replace chemical nitrogen and phosphorus by 25.

• Stimulate plant growth.

• Activate the soil biologically.

• Restore natural soil fertility.

• Provide protection against drought and some soil
  borne diseases.

Plant Growth
Photosynthesis Co2 H2O
Carbohydrates(CHO) O2
Innumerable experiments prove there is
significant increase in Yields by application of
secondary and micronutrients along NPK nutrients.

• Nutrients are taken up primarily by the roots of
  an aqueous solution in the soil.

12
CAUTIONS AND LIMITATIONS OF BIOFERTILIZER

• Never mix with chemical nitrogen fertilizers.
• Never apply with fungicides, plant ash etc. at
  the same time.
• Never directly expose to sunlight.
• Do not keep used solution overnight.
• Store at room temperature, not below Oº C and
  over 35º C.
