Best Applications for Sub-Surface Drip Irrigation

Sub-surface drip irrigation is an irrigation technique that varies from the conventional practices which most individuals are used to. Unlike surface irrigation or traditional drip irrigation, this method uses drip tubes buried under the soil surface to supply water to plant roots. The depths at which the drip tubes are buried depend on the crop being watered and the farming practices employed. It is a costly watering system because it requires expert design and maintenance, but the fact that it delivers water directly to plants roots makes it very effective.

Sub-surface irrigation eliminates many of the effects of conventional irrigation methods such as ponding, surface infiltration, surface water runoff (leading to erosion), and excessive water losses through evaporation. Water moves out of the drip tubes in all directions and wets the soil around roots. With a well-managed sub-surface irrigation system, it possible to maintain a high degree of uniform water application throughout your fields. Plus, water is only applied underground instead of to the soil surface where weeds could easily germinate. This reduces weed growth and makes it possible for crops to enjoy more nutrients from the soil.

Best Applications

In arid, semi-arid, hot and windy areas – The system is best for such areas with low rainfall and limited water supply because of its low evaporation rates compared to conventional irrigation methods. Countries such as Israel heavily rely on this technique in their farming.

For weed control – The system can help reduce weed growth substantially.

Growing crops that require dry surface conditions – Some crops benefit from a drier soil surface and foliage because of reduced potential for fungal diseases.

Medium and large-scale production – The system is relatively complex and in most cases automated, so it’s not best for small-scale farming.
