Action: Injudicious use of fertilizers

Impact: Deteriorate soil properties.

Therefore, decrease in soil fertility and

productivity

Overcome: INM / organic farming

Component: Fertilizer, Manure,

Biofertilizer

• Indian soils being very poor in organic matter and major

plant nutrients,

• Addition of regular doses of organic manures in requisite

quantities can help restoration of soil health and also

compensate the loss of basic nutrients of every year from

soil due to uptake of plants.

• Use of organic manure is extremely essential for better

plant productivity and maintaining the fertility of soil to

ensure sustainable production.

Classification of organic manures

Page 6: Potentiality  of  deoiled seed cakes as organic manure on tree growth

6

• Deoiled cakes are the by-products of oil

seed crops or trees.

• After oil is extracted from oil seeds, the

remaining solid portion is called deoiled

cakes.

• It is widely used as animal feed or

organic manure.

• Oil cakes are the important and quick

acting organic nitrogenous manure.

Deoiled cakes

Page 7: Potentiality  of  deoiled seed cakes as organic manure on tree growth

A. Edible Oil Cakes

Are those cakes which are edible in nature

Such oil cakes are used for feeding to animals

Such as:

Mustard oil cakes,

Groundnut cake,

Sesame or Til cake,

Coconut cake etc.

7

Types of Deoiled Cakes

Page 8: Potentiality  of  deoiled seed cakes as organic manure on tree growth

These oil cakes are not suitable for feeding to animals

Therefore, they are mainly used as manures

These are a good source of nutrients.

Such as : Castor cake

Neem cake

Mahua cake

Karanj cake

Sal meal cake etc.

8

B. Non-edible oil cakes

Page 9: Potentiality  of  deoiled seed cakes as organic manure on tree growth

Mahua (Madhuca indica) Jatropha (Jatropha curcas)

Karanj (Pongamia pinnata) Neem (Azadiractha indica)

Sal (Shorea robusta)

The non-edible oil cakes contain a harmful toxic substance,

which make them unsuitable for feeding to cattle.

Manufacture of organic fertilizer because they are

concentrated organic manure.

Improves the soil properties i.e. Physical, chemical and

biological

Deoiled seed cakes are rich in NPK content than bulky

organic manures (Table: Yawalkar and Agrawal (1962)

They also have micro nutrients, which are very important

for plant growth.

Quick acting organic manures as C:N ratio is usually

narrow (5-15)

Improve the soil reaction

12

Page 13: Potentiality  of  deoiled seed cakes as organic manure on tree growth

It increases the microbial population and

activity

Biological nitrogen fixation

Solubilization of insoluble phosphates and

other nutrients

There is improvement in soil structure, water

holding capacity, exchange capacity, seed

germination and reduction of soil erosion.

13

Page 14: Potentiality  of  deoiled seed cakes as organic manure on tree growth

Oil prevents rapid conversion of N

Some oil cakes contains alkaloids which are responsible for slow nitrification of their N due to effects of on soil microorganisms

Castor cake has also good vermicidal effect against white ants

Groundnut cake has the highest nitrification rate.

Mahua cake is very poor in N and takes a long time to nitrify. When used as manure it has got to be applied to the soil two to three months before sowing/planting of crop.

Seed cakes of Jatropha, Karanj, Castor and Neem have pesticide materials, which save the plants from pests.

Agricultural products: Used in manufacturing organic

pesticides, insecticides.

Cosmetics: Used in various skin and body lotions, skin

creams and moisturizers. It is also used to make face

packs etc.

Pharmaceuticals: It is used to manufacture medicated

creams curing pimples, blemishes and other skin

infections. It is also used to manufacture birth control

products.

• Before their organic nitrogen is used

by the plants, it is converted through

bacterial action into readily usable

form of ammonical nitrogen and

nitrate nitrogen.

• These organic manures are relatively

slow acting, but they supply

variables nitrogen for a longer

period. 19

From the foregoing discussion it can be concluded that the

application of deoiled cakes as organic manures enhances the

growth and biomass production of tree seedlings.

Also low C: N ratio its decomposition rate is faster than easily

available for plant nutrients and reduces population of plant-

parasitic nematodes.

Among various deoiled seed cakes mahua, neem, castor, sal,

karanj, mustard etc. proved that the good potentiality of deoiled

seed cakes as an effective and much cheaper source of plant

nutrients.
