The three main objectives of drainage in agricultural land are: –
Drainage to prevent or reduce waterlogging
; – Drainage to control salinity; – Drainage to make new land available for agriculture.
What are the functions of drainage?
One of the drainage system’s functions is
to collect surface water and/or ground water and direct it away
, thereby keeping the ballast bed drained. The drainage system must also protect the substructure from erosion, from becoming sodden, and from losing its load-bearing capacity and stability.
Why is land drainage important?
Drainage
ensures that your soil is properly aerated
. If there is too much standing excess water, it can congest your crops. If you have a slope, installing drainage on the slope can reduce the risk of soil slippage. Drainage ensures good soil structure which is good for root development.

promotes beneficial soil bacteria activity and improves soil tilth
. ii. There is less surface runoff and soil erosion on drained land.
What are the objectives of drainage system?
The three main objectives of drainage in agricultural land are: –
Drainage to prevent or reduce waterlogging
; – Drainage to control salinity; – Drainage to make new land available for agriculture.

- 6.2. 2 Subsurface drainage. Subsurface drainage is the removal of water from the rootzone.
What are the requirements of drainage system?
A good drainage system should satisfy the following requirements.
Surface water should not percolate to track
One of the basic requirements of a good track drainage system is that surface water from rains and adjacent areas should not percolate and seep into the formation of the track.
What are the effects of poor drainage system?
Poor drainage can
lead to flooding, resulting in property loss
, and people may even be forced to move to escape floodwaters. Flooding may also damage water supply infrastructure and con- taminate domestic water sources.
What is the meaning of drainage system?
In geomorphology, a drainage system is
the pattern formed by the streams, rivers, and lakes in a particular drainage basin

Which of the following are benefits of artificial drainage?
- Prevents Standing Water. The benefits of proper drainage include no standing or pooling water in low-lying areas. …
- No Mosquitoes! …
- Conserves Water. …
- Complex System Means Smooth Flow.
What is agricultural drainage and their importance?
Drainage systems
save energy used in irrigation by controlling soil moisture
. They prevent crop loss from flooding and maintain agricultural soil conditions so as to maximize yields.
