TOPIC :- Demonstrate a method to increase fertility of land to increase crop production

What is soil fertility ??????

• It is the simple method of making the soil fit for use and also for the better use of the earth’s resources.

• It refers to the use of different methods to increase the soil fertility by the use of many type of external and internal sources available :-

Ploughing – The turning up of soil. Tilling – The manual improvement in soil physically Liming – Obtaining higher yield from same type of crop Use of earthworms – Collection of earthworms in a place Vermi composting – Collection of reed worms in a place Use of Manures(recommended) Use of Fertilizers( upto a limited use)

PROCEDURE IN CURRENT USE TO INCREASE FERTILITY OF SOIL AND ITS SIDE EFFECT• EXCESSIVE USE OF FERTILIZERS

1) Ground water contamination.

2) Acid rain

3) Ozone depletion

4) Killing of bacteria present in soil.

5) Can cause cancer also.

6) Marine dead zones

7) Change the chemical nature of soil

8) Depletion of water table

PROCEDURE IN CURRENT USE TO INCREASE FERTILITY OF SOIL AND ITS SIDE EFFECT

• EXCESSIVE USE OF PESTICIDES AND INSECTISIDES.

1) Abdominal pain

2) Lung disease

3) Serious arthritis problem

4) Even can cause death

5) Pollutes the environment

6) Increases the level of CFC’s

7) Hence increases Global Warming

THE CONDITION OF INDIAWORLDWIDE

India also called as the land of gold, is now being exploited due to the narrow mindness of people. They because of

their small productive skill, are still using traditional methods and so are not getting success. Here is a table which shows the

placement of India worldwide

WHAT SHOULD BE DONEIN ORDER TO PROTECTCROPS(MY METHOD) 1) GROWING MORE PER ACRE

LEAVES MORE LAND FOR NATURE.- Now, without the use of modern facilitiesThe farmers are growing crops in a big pieceOf land. Without doing so, if they will use lessLand but modern methods, then more crops

Can be grown

WHAT SHOULD BE DONEIN ORDER TO PROTECTCROPS(MY METHOD)

2) DOING MULTISTOREY AGRICULTURE- In this method, we will be taking a small piece

of land and then supply it with soil, with the provisions like drip irrigation, provision of

sunlight, and by use of sprinklers. So doing so, a small piece of land can be

used to obtain more profit by growing a no. of crops at the same time.

ALTERNATIVE METHODS THAT I SUGGEST.

1) Use of neem dust - This method can help us in maintaining the

fertility of soil and can also keep the plant free from pests

2) Biological pest control – This is the method of releasing the special animals or planting seeds that do

not harm the crop but kill the pests

ALTERNATIVE METHODS THAT I SUGGEST.

3) Use of vermicompost and earthworm – In this, we will allow reed worms and earthworms to settle in field and in this way, fertility of soil can be increased.

4) Biological weed control – In this, we will be releasing the insects who will be eating the weeds, but will not destroy

crop. Hence, the use of weedicides will be prevented.

ALTERNATIVE METHODS THAT I SUGGEST.

5) Planting of zaid crops – We will be planting leguminous plants in between of two season crops so that the fertility

of the soil can be maintained

6) Rhizobium– This is the chemical necessary for nitrogen capacity of soil and can either be provided by the planting of legumes or by the

use of manures.

ADVANTAGES OF MY METHOD

It saves time and additional work of labour, too.It is cheaper and can be practiced easily.With the help of government schemes, the farmers can get good seeds and facilities at a low rate.This leaves more land for the social use of human beings.This is profitable for developing county, especially for our country, INDIA.

THUS, BY DOING SO WE CAN ACHIEVE OUR GOAL

Hence we should take a pledge of increasing % of

agricultural output from 7 to 25 % if we

want our country INDIA to succeed in

the field of AGRICULTURE.THANK YOU
