DRIP IRRIGATION IN NIGERIA

DRIP IRRIGATION IN NIGERIA

Drip irrigation in Nigeria and world in general is sometimes called trickle irrigation and involves dripping water onto the soil at very low rates (2-20 litres/hour) from a system of small diameter plastic pipes fitted with outlets called emitters or drippers. Water is applied close to plants in drip irrigation so that only part of the soil in which the roots grow is wetted, unlike surface and sprinkler irrigation, which involves wetting the whole soil profile. With drip irrigation water, applications are more frequent (usually every 1-3 days) than with other methods and this provides a very favourable high moisture level in the soil in which plants can flourish. Drip Irrigation in Nigeria remains one of the most effective and innovative forms of irrigation in the world today.

BENEFITS OF DRIP IRRIGATION

Drip irrigation is adaptable to any farmable slope. Normally the crop would be planted along contour lines and the water supply pipes (laterals) would be laid along the contour also. This is done to minimize changes in emitter discharge as a result of land elevation changes in drip irrigation.

Drip irrigation is most suitable for row crops (vegetables, soft fruit), tree and vine crops where one or more emitters can be provided for each plant. Generally only high value crops are considered because of the high capital costs of installing a drip irrigation system.

Drip irrigation is suitable for most soils. On clay soils water must be applied slowly to avoid surface water ponding and runoff. On sandy soils higher emitter discharge rates will be needed to ensure adequate lateral wetting of the soil in drip irrigation.

Fertigating with drip irrigation can also increase the optimum yield of 50-200% while reducing the cost of labour to be used on the farm

Our goal at Deejoft is to make farming easier and farmers less dependent on rain whereby they can farm throughout the year using drip irrigation system in Nigeria. Farmers will have the opportunity to use our consultancy service, buy drip irrigation kits from us and install the drip irrigation for them at an affordable price.

WATER SUITABILITY FOR DRIP IRRIGATION

One of the main problems with drip irrigation system in Nigeria is blockage of the emitters. All emitters have very small waterways ranging from 0.2-2.0 mm in diameter and these can become blocked if the water is not clean. Thus it is essential for drip irrigation water to be free of sediments. If this is not so then filtration of the irrigation water will be needed.

Blockage may also occur if the water contains algae, fertilizer deposits and dissolved chemicals which precipitate such as calcium and iron in drip irrigation. Filtration may remove some of the materials but the problem may be complex to solve and requires an experienced engineer or consultation with the equipment dealer to solve the drip irrigation system in Nigeria problem.

Drip irrigation In Nigeria is particularly suitable for water of poor quality (saline water). Dripping water to individual plants also means that the method can be very efficient in water use. For this reason drip irrigation is most suitable when water is scarce.

WHAT DRIP IRRIGATION SYSTEM CAN DO?

FERTIGATION: Apart from the fact that a drip irrigation can be used to supply water to your crops. Drip irrigation system can also be used to pass soluble fertilizers like NPK, Mono Potassium Phoshate, Calcium Nitrate, Potassium Nitrate, Humates like humic acid and fluvic acid and other fertilizers can be mixed in water and sent to your crops through drip irrigation system.

CHEMIGATION: Chemigation in  is an inclusive term in drip irrigation referring to the application of a chemical into or through an irrigation system. It includes the application of fertilizers, acids, chlorine and pesticides.

UNIFORM APPLICATION

Chemigation in drip irrigation facilitates the uniform distribution and precision placement of fertilizers and other chemicals.

TIMELY APPLICATION

In most cases, materials can be applied regardless of weather or field conditions in drip irrigation system.

REDUCED APPLICATION COSTS

In general, cost of application by chemigation is about one-third the cost of conventional application methods in drip irrigation.

IMPROVED MANAGEMENT

Timely applications of small but precise amounts of fertilizer directly to the root zone allow growers to effectively manage fertilizer programs in drip irrigation. This conserves fertilizer, saves money and optimizes yield and quality for good drip irrigation system..

REDUCED SOIL COMPACTION

Chemigation reduces tractor and equipment traffic in fields. This reduces soil compaction in drip irrigation.

REDUCED EXPOSURE TO CHEMICALS

Chemigation in drip irrigation minimizes operator handling, mixing and dispensing of potentially hazardous materials. Also, people and non-target crops are not exposed to inadvertent chemical drifts in drip irrigation system.

REDUCED ENVIRONMENTAL CONTAMINATION

When used with the recommended safety devices, properly-designed and accurately-calibrated chemigation systems help preserve quality of the environment in drip irrigation

Chemigation in drip irrigation can save time, reduce labor requirements, and conserve energy and materials. However, chemigation in drip irrigation is beneficial only to the extent that the drip irrigation system is adequately designed, fully functional and properly managed.

In many situations, chemigation in drip irrigation is as good or better than conventional application methods. However, conventional application is still preferred or required for some materials. Never inject any material that is not labeled and recommended for the crop and for injection through the system in drip irrigation. Always follow label directives.
