Question

Give 3 advantages of each of the following system of irrigation:
A. Well Irrigation
B. Tank Irrigation.
C. Canal Irrigation
D. Sprinkler Irrigation

Answer 1

Answer:

Irrigation makes it possible to grow cash crops. It gives good returns to the farmer. ...

It improves the groundwater storage as water lost due to seepage adds to groundwater storage.

It improves the yields of crops. ...

We use it to help the growth of crops during the period of not enough rainfall.

Explanation:

D. Sprinkler type of irrigation does not involve any loss of water by seepage or evaporation, as water is supplied through pipes, and it is not exposed to the Sun.

C.Canal irrigation is more suitable in the Northern Plains because here the rivers flow through flat terrain and are perennial.

A.Wells can be dug at a very low cost within the means of poor farmers.

ii) Oxen can be utilised for drawing water from the wells at no extra cost.

Disadvantages:

i) Wells depend on underground water resources whose distribution varies from region to region.

ii) Availability of electricity and diesel to operate tubewells causes many problems and is costly for the farmers.

B.Tank irrigation is defined as an artificial means applied for improving the cultivation in India. Tank irrigation is in practice in Peninsula India including Maharashtra and Gujarat.Tank irrigation has reached its highest perfection in the south, especially in Andhra Pradesh, Telangana and Tamil Nadu.

Answer 2

Answer:

Three advantages of well irrigation are :

(ii) Well is an independent source of irrigation and can be used as and when the necessity arises. It is not controlled by other agencies. (iii) Several chemicals such as Nitrates, Chlorides, Sulphates are mixed in well water naturally which add to the fertility of the soil.

Advantages of Irrigation by Tanks:

2. It maintains level of groundwater. 3. Where construction of wells is very costly due to hard rock surface, irrigation by tank is cheaper.

Advantages of Canal Irrigation:

Un-irrigated wastelands can be developed by canal irrigation, which would increase the quantity of biomass in the area. 2. Economic development can be expedited by avoiding dangerous droughts. Dependence on rainfall can be minimized through canal development.

Advantages Of Sprinkler Irrigation:

Suitable for all types of field condition (except heavy clay soil).

Uniform distribution of water with high efficiency.

Less land loss provides more land area for cultivation.
