by Drip irrigation, also known as trickle irrigation, is an irrigation method that saves water and fertilizer by allowing water to drip slowly to the roots of plants. In drip irrigation, water is distributed through a network of valves, pipes, tubing, and emitters. Drip irrigation systems deliver water using low pressure directly to the base of the plants in either a solid stream or micro-spray. Compared to surface irrigation methods like flooding, drip irrigation is more efficient because it applies water directly to the root zone and minimizes evaporation.
Key Benefits of Drip Irrigation
Water Savings
MENA Drip Irrigation System uses 30-60% less water than surface irrigation methods like flooding or spray irrigation. Since water is applied at a slow, steady rate, drip irrigation prevents excess water loss due to deep percolation, runoff, or surface evaporation. Only the root zone of the plants is watered.
Fertilizer Savings
Drip irrigation improves fertilizer use efficiency compared to surface irrigation. Fertilizers can be applied through the irrigation system directly to the root zone. Less fertilizer is wasted since it is not washed away by excess water.
Increased Crop Yields
Applying water directly to the root zone of plants improves plant health and growth. Crops have consistent access to water and nutrients, which leads to higher crop yields. Yields can increase by 20-90% depending on the crop and other conditions.
Labor Savings
Drip irrigation systems require less labor than surface irrigation methods. The systems operate automatically through a network of valves, pipes, and tubing. Labor needs are limited to system installation, maintenance, and fertilizer applications.
Uniform Water Application
Water is applied at low pressure and low volume through individual emitters spaced along drip lines. This ensures a uniform water application over the irrigation zone. The system can irrigate uneven land terrain easily without ponding or runoff.
Weed Control
Weeds often cannot compete with crop plants for water and nutrients applied through drip irrigation. Less weeds need to be controlled since the surface between rows stays relatively dry with drip irrigation.
Suitability for MENA Drip Irrigation System Market
The MENA (Middle East and North Africa) region is characterized by arid climates with limited freshwater resources. Surface irrigation methods are commonly used but involve significant water losses. Adopting drip irrigation provides an ideal solution for agricultural water management in the MENA region. Since drip irrigation can achieve high efficiency levels even with saline water, it opens up the potential for using marginal quality water sources to grow crops. Higher and more consistent crop yields can be achieved with drip irrigation compared to traditional surface methods. This helps address national food security concerns in many MENA countries. Minimizing water use in agriculture is also critical given growing water scarcity issues in the region.
Components of a Typical Drip Irrigation System
Below are the typical components included in a drip irrigation system:
Water Source – The system is connected to a pressurized water source like municipal or well water. Surface water sources like rivers or lakes require a pump to pressurize the water for the irrigation system.
Filtration – A filter, usually a screen or sand media filter, is installed to remove suspended particles that could clog emitters. The filter needs to be backwashed periodically.
Control Valves – Aqua-traxx or gear drive control valves automatically regulate water flow according to the irrigation schedule program. This controls water distribution to different zones.
Mainline and Submain Lines – Polyethylene pipes carry water under pressure from the water source to control valves and then to laterals spaced throughout the field.
Laterals – Flexible polyethylene tubing or rigid PVC pipe branches connect to submains and run parallel to crop rows. Emitters attach directly to laterals.
Emitters – Small emitters punctured into laterals precisely control water discharge rates, usually 1-4 L/h. Common emitter types include inline, on-line, and pressure compensating point source emitters.
Flush Valves – Isolated flush valves installed at the ends of laterals are used to flush out sediment before and after an irrigation cycle.
Filtration units scrub water to remove particles that could clog emitters before it enters the irrigation system. An appropriately sized pump pressurizes the filtered water and delivers it through polyethylene mainlines to control valves. Control valves regulate water flow to sub-mainlines that branch out through the field. Laterals consisting of polyethylene tubing or PVC piping connect to sub-mains and run parallel to crop rows. Individual point-source emitters spaced along laterals precisely meter water discharge rates directly to the crop root zone. The entire system operates automatically according to a programmed irrigation schedule. Isolated flush valves located at lateral ends flush sediment from the system periodically. Proper installation, maintenance, and emitter selection are critical for optimum drip irrigation system performance over many years of operation.
New Technologies Advance in MENA Drip Irrigation System Market
Drip irrigation technology continues advancing to achieve higher water and fertilizer use efficiencies. Some new technologies include:
Variable Rate Irrigation (VRI) – VRI systems utilize soil moisture sensors and GPS technology to dynamically vary water application based on precise location needs within a field in real-time.
Smart Controllers – Internet and cloud-connected controllers allow remote monitoring and control of irrigation systems from any location using smartphones and computers.
