Question

Describe two methods of irrigation which conserve water.​

Answer 1

Explanation:

• The process of watering the crops is called irrigation. Two methods of irrigation are:
• (i) Sprinkler system : This system is used on the uneven land where less water is available.
• (ii) Drip irrigation: This system is used to save water as it allows the water to flow drop by drop at the roots of the plants.

Answer 2

Answer:

Rain water harvesting

Drip irrigation

Explanation:

RAIN WATER HARVESTING:

Rainwater harvesting (RWH) is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer, or a reservoir with percolation, so that it seeps down and restores the ground water.

DRIP IRRIGATION:

Drip irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface. The goal is to place water directly into the root zone and minimize evaporation.
