Guide on how to start drip irrigation system. There are different types of irrigation systems such as sprinkler irrigation, surface irrigation or drip irrigation. Drip irrigation basic function is application of drip water to plants and roots. The method involves surface or below surface watering of plants. Direct maximization of water directly to root system is the main function of drip irrigation. It distribute the water evenly and efficiently through a network of tubes, emitters, valves and pipes. It requires proper analysis of climate, soil type, topography and type of crop farmed.
Uses of Drip Irrigation
Drip irrigation has many practical uses in farm applications. We use the system in home gardens, greenhouses or large commercial farms. The systems main purpose is to supplement water supply to the farm and best suited for areas with acute water shortage.
You can find the system in banana plantations, cotton fields, tomato farms and sugarcane plantations. Perfect for crop farming, maize production, citrus, eggplants and strawberry fields.
• Home gardens
• Large commercial farms
• Supplement water supply to the farm
• Used in areas with acute water shortage
Advantages of Drip Irrigation
Drip irrigation is operated at lower pressure than other pressurized systems it defectively reduces energy costs. Other advantages are dry foliage, reduced disease in plants, easy fertilization and reduced fertilizer waste.
There is less weeds, soil erosion and applicable to different soil types. It is possible to maintain moisture with root zone. Field leveling not necessary and low nutrient loss in soil.
The farmer does not have to level the field because the system accommodates any field type. The farmer can easily recycle non-potable water with easy water management and better efficiency.
A major advantage is reduced labor costs and practicable in all soil types.
• The system provides high water application and efficiency
• There is huge reduction in labor costs
• There is reduction in soil erosion and weed growth
• Operated at lower pressure than other pressurized systems
• Effectively reduces energy costs
• Dry foliage, reduced disease in plants
• Easy fertilization and reduced fertilizer waste
• Applicable to different soil types
• Easy to maintain moisture IN root zone
• Field leveling not applicable
• Low nutrient loss in soil
Disadvantages of Drip Irrigation
Drip systems are designed for high efficiency causes no leaching fraction. Salt in irrigation water accumulates in root zone. This is prevalent at the edge of wetting pattern.
The initial cost of installation is high as opposed to overhead system. It provide unsatisfactory results when top soil fertilizers require sprinkler activation.
Other disadvantages include clogging of system because of poor maintenance or water filtration. They system causes huge cleanup costs after harvesting, disposal, tape winding or reuse.
Installing the system requires proper mapping of climate, soil type, water levels and type of crop. The PVC pipes are prone to damage while tubes are susceptible to sun damage.
This adds to the high cost of replacement of component parts in the system. Subsurface drip provides additional challenges like excess or low water application. The control of night frost is a serious challenge same as lighter soil subsurface for germination purposes.

Components of Drip Irrigation System
Components include pressure control valve, distribution lines and pumps. Others are dripper, micro spray head, inline drip tube and emitter.
You have the small diameter polyethylene tube, backwater controller, pressurized water source, water filter and hydraulic control valve. To make connections you need accessories and poly fittings.
