 Question:-

difference between irrigation and ddrainage

 Answer:-

DRAINAGE

When precipitation occurs, the water falling on the ground will infiltrate into the soil after meeting the initial abstractions like interception and depression storage. When the conditions are so created that the crop root-zone gets deprived of proper aeration due to the presence of excessive moisture or water content, the tract is said to be waterlogged.

The water logging affects the land in various ways. The various after effects are the following:

1. Creation of Anaerobic Condition in the Crop Root-Zone

2. Growth of Water Loving Wild Plants

3. Impossibility of Tillage Operations

4. Accumulation of Harmful Salts

5. Lowering of Soil Temperature

6. Reduction in Time of Maturity

So, the excess water content on the surface and in the crop root zone should be removed properly for the healthy growing of plants and to maintain the soil fertility.

Drainage refers to the removal of excess water from the ground surface as well as from the subsurface soil to facilitate the proper growth of plants and to avoid the hazards due to water logging.

It can be done by using tile drains or mole drains (in clay soil).

-----------------------------------------

IRRIGATION

In the absence of sufficient rain, water should be supplemented for the plants to meet their daily consumptive use.

Irrigation refers to the application of controlled amounts of water to plants at needed intervals.

There are different methods of irrigation including surface irrigation, subsurface irrigation, drip and sprinkler irrigation.

Drip irrigation is proved to be the most efficient among all the methods of irrigation, as it allows water to drip slowly to the root zone of the crop.

DRAINAGE

  • When rain falls on the ground, the water will penetrate into the soil after passing through the early abstractions of interception and depression storage.
  • The tract is considered to be waterlogged when the conditions are such that the crop root-zone is deprived of sufficient aeration due to the presence of excessive moisture or water content.

  • Water logging has a variety of effects on the soil. The following are some of the different after effects:
  • 1. Establishing anaerobic conditions in the root zone of the crop
  • 2. The Development of Water-loving Wild Plants
  • 3. Tillage Operations Are Impossible
  • 4. The Build-Up of Harmful Salts
  • 5. Soil Temperature Reduction

IRRIGATION

  • Water should be provided for the plants to satisfy their daily consumptive use if there isn't enough rain.
  • Irrigation is the process of applying a regulated amount of water to plants at regular intervals.
  • Irrigation may be done in a variety of ways, including surface irrigation, subsurface irrigation, drip irrigation, and spray irrigation.
  • Trickle irrigation has shown to be the most efficient of all irrigation systems because it allows water to drip gently to the crop's root zone.
