Drip tape is the emitters used to efficiently and accurately deliver water droplets onto the plant roots. The emitters are pinhole sized to minimize the loss of water and channel water directly to the required plant.
Drip tape types
Drip tapes vary in sizes depending with wall thickness, material type and the drip length. The tape come with different intervals of 10 centimeters, 15 centimeters, 20 centimeter, 30 centimeter and 40 centimeters.
The intervals are the spaces between the emitters. The emitters are usually single or double emitters. Double emitters are the best considered because of large water volume discharged from the main tubing.
Drip tape is made of plastic, polyethylene, and is sold flat on reels. The wall thickness typically ranges from 0.1–0.6 mm. Thicker walled tapes are commonly used for permanent subsurface drip irrigation and thinner walled tapes for temporary type systems in high-value crops
The drip tape is well designed to discharge one litter of water per hour. This discharge ensures water is efficiently and economically used
The economical water budget is the major determinant of the production cost. This dictates the type of plant to be grown. However, Broad leaved plants require much water as compared to small leaved plants. This will affect the drip tape emitters to be used.
Drip lines are stock in form of rolls. The rolls contain different lengths of 1000 meters, 1200 meters and 1300 meters. The choice of the drip depends on farmer’s garden length, types of the plant to be grown and the economical budget.
Advantages of drip
- Extensive land leveling is not required, drip irrigation can be employed in all landscapes;
- Irrigation water can be used at a maximum efficiency level and water losses can be reduced to a minimum;
- Soil conditions can be taken into account to a maximum extent and soil erosion risk due to irrigation water impact can be reduced to a minimum;
- Fertilizer and nutrients can be used with high efficiency; as water is applied locally and leaching is reduced, fertilizer/nutrient loss is minimized (reduced risk of groundwater contamination);
- Weed growth is reduced as water and nutrients are supplied only to the cultivated plant;
- Positive impact on seed germination and yield development;
- Low operational costs due to reduced labor requirement, in particular energy cost can be reduced as drip irrigation is operated with lower pressure than other irrigation methods.
Other irrigation equipment related to drip
For the drip tape to be much effective, it must be used together with other equipment. The commonly used equipment may include starter connectors, drip takeoffs, drip end caps and Fertigation machine.
