There are some plants that need to be watered regularly if they are to survive and grow. If you go on a vacation for even a few days and do not make arrangements to water them, they will wither away and dry. There are other plants whose roots get damaged if you water them too often. These plants usually grow well in dry climates .
Irrigation systems today consist of :
The PVC pipe and electric valves are usually buried under the surface. The timer controls the on / off period.
Drainage in gardens and agricultural lands is important, especially in areas with a high rainfall. Some soils are more prone to waterlogging and retain the rainwater, so providing proper drainage is important.
It can damage the roots of the plants and destroy the plants and / or crops.
Vermicompost is produced by the breakdown of organic matter- usually dead leaves , flowers and fruits by earthworms.
Water is needed by all living things - both plants and animals. In many areas, when natural resources for supply of water are inadequate, irrigation is needed. Irrigation helps in large areas from limited water sources to attain maximum benefits especially in dry areas and where the rainfall is very less.
It also saves time.
There are different forms of irrigation used like drip irrigation, sprinkler irrigation, surface irrigation, depending on the crop and the amount of water available.
a. In drip irrigation water is allowed to pass to the roots of the plants drop by drop
b. in sprinkler irrigation water is allowed to pass to one or more locations and the water is sprinkled to the plants all round it.
c. In surface irrigation the water is allowed to pass through channels where there is slope gradient.
