Question

What is irrigation? What are the sources of irrigation? Name three traditional methods of irrigation. Explain two modern methods of irrigation.

Answer 1

Answer:

IRRIGATION : Irrigation is the artificial process of applying controlled amounts of water to land to assist in production of crops. Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall.

SOURCES OF IRRIGATION : The main sources for irrigation water are groundwater from wells, surface water, drainage ponds, rain and municipal water. Drilled wells are a clean source of water for many greenhouse operations however, the water yield from drilled wells is usually limited.

TRADITIONAL SOURCES OF IRRIGATION :

1. Moat

2. Chain pump

3. Dhekli

MODERN METHODS OF IRRIGATION :

Drip irrigation is the most used irrigation system these days. In the drip irrigation, we lay plastic pipes in rows near the crops or plants. These pipes have holes in them. The water seeps from these holes drop by drop, hence the name drip irrigation. Drip irrigation is one of the most efficient irrigation methods as it reduces water wastage in agriculture.

Sprinkler systems mimic the phenomenon of rain. In sprinkler systems, the pipes carry water to central locations on the farm. The sprinklers placed there, distribute the water across the fields. The sprinkler method is one of the most efficient irrigation methods to irrigate the uneven land for agriculture. In addition, sprinkler systems provide the best coverage regardless of the size of the farm.

What is Irrigation?

Ans:-Irrigation means the watering of land to make it ready for agriculture. It is the process of application of water to crops through artificial channels to grow them.

What are the sources of irrigation?

Ans:-The main sources for irrigation water are groundwater from wells, surface water, drainage ponds, rain and municipal water.

Importance of irrigation :-

Ans:- It enables growth and photosynthesis in Plants. Plants absorb minerals and nutrients from the soil via their roots. These minerals dissolve in the water present in the soil. Then the water transports these nutrients to all parts of the plant. In this way, it enables growth and photosynthesis.

Traditional irrigation methods:-

Ans:-These irrigation systems were used in earlier years. However, even today some small farms in rural areas adopt these. Although they are cheaper than modern methods, they are not as efficient. Because they need human or animal labour to function.

Modern irrigation methods :-

Ans:-Drip irrigation, sprinkle irrigation are modern types of irrigation.
