What irrigation systems would you use for dry areas?

April 28, 2019

You can get irrigation water from groundwater, rivers, lakes, springs or wells and boreholes. When irrigation water supply is limited, it is still recommended to meet, as far as possible, the basic water requirement for crops.

There are different types of irrigation systems for dry areas;

  • Drip irrigation

Drip irrigation usually delivers water directly to the root zones of plants; hence water is not wasted. It works for carrots, tomatoes, Peppers, watermelons, apples, onions, cucumbers, corn, melons radishes, spinach, soybeans, pears, squash and cabbages. Drip irrigation involves dripping water onto the soil from small plastic pipes which are fitted with drippers as outlets set at a low rate. Water is delivered close to the plant’s root zones. This is unlike surface and sprinkler irrigation Tulsa in which the whole soil profile is irrigated. When you use drip irrigation, water application is more frequent and this provides a favourable high moisture level in the soil, allowing plants to flourish.

  • Furrow irrigation

This is probably one of the oldest methods of irrigating fields. Here, you lead water down small trenches running through the crops.  Furrow irrigation attracts a low initial investment of equipment. Water pumping costs are also low. 

  • Alternate wetting and drying irrigation

This is a water management technique practised in dry areas. It’s used to cultivate irrigated lowland rice using less water than the usual system where you maintain continuous standing water in the crop field. This is a system of controlled and intermittent irrigation. Here, periodic drying and re-flooding scheduling approaches are followed. You allow the fields to dry for a few days before re-irrigation and without stressing the plants. This system reduces water demand for irrigation without reducing crop yields. It has also become a recommended practice in the water-scarce irrigated areas. This method can save water up to 38% without adversely affecting your yields.

  • Supplemental irrigation 

 This is the addition of limited amounts of water to rainfed crops inorder to improve and stabilize the yields. This is especially so when rainfall fails to provide enough moisture for normal plant growth. It is a practice adopted for rainfed crops and is practised during long dry spells of rain when crop show those wilting symptoms.

Buried diffuser irrigation

This is a new technique for underground irrigation which you can use for fruit trees, ornamental trees, shrubs, vegetables and forest trees in fields and greenhouses. Injected water is used by arboriculture taproot cultures during summer and drought periods. This leads to the exploitation of the water, which is conserved in deep soil layers can cover the needs of the trees for several years. During the long drought period, the trees can produce normally using the ‘injected water.
