INDIAN GEOGRAPHY

Detailed explanation-1: -Sub Irrigation, also known as Seepage Irrigation, is a method of irrigation in which water is delivered to the plant root zone from below the soil surface and absorbed upwards. Sub-irrigation is used to grow field crops such as tomatoes, peppers, and sugar cane in areas with high water tables. More items

Detailed explanation-2: -Subirrigation applies water below the soil surface to raise the watertable into or near the plant root zone. Subirrigation is not often used in arid or semi-arid irrigated areas where irrigation is often needed to germinate crops. It is typically used in conjunction with subsurface drainage, or controlled drainage.

Detailed explanation-3: -Subsurface drip irrigation is a low-pressure, high efficiency irrigation system that uses buried drip tubes or drip tape to meet crop water needs. Subsurface irrigation saves water and improves yields by eliminating surface water evaporation and reducing the incidence of weeds and disease.

Detailed explanation-4: -Subirrigation. Subirrigation has been used for many years in field crops in areas with high water tables. It is a method of artificially raising the water table to allow the soil to be moistened from below the plants’ root zone.

Detailed explanation-5: -In agricultural production fields, subirrigation is an irrigation practice to control the water table at certain levels by elevating or lowering it. This is accomplished by artificial-ly adding water to the soil profile underground to moisten the crop root-zone for a determined period.
