Drip irrigation is a form of irrigation that saves water and fertilizer, by allowing water to drip slowly to the roots of many different plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing and irrigation for various reasons, often including concern about minimizing evaporation.
Modern drip irrigation and drainage systems research, was expanded in the 1920s to include the application of perforated pipe systems. The usage of plastic to hold and distribute water in drip irrigation was later developed in Australia by Hannis Thill.
Usage of plastic emitter in drip irrigation was developed in Israel by Simcha Blass and his son Yeshayahu.Instead of releasing water through tiny holes easily blocked by tiny particles, water was released through larger and longer passageways by using velocity to slow water inside a plastic emitter.
The first experimental system of this type was established in 1959 by Blass who partnered later with Kibutz Hatzerim to create an irrigation company called Netafim.Together they developed and patented the first practical surface drip irrigation emitter.
The review of past studies show, that the solution to the problem of growing groundwater scarcity and persistent groundwater resource degradation across regions is two-fold. The first is the supply side management practices like watershed development, water resources development, through major, medium and minor irrigation projects. The second is through the demand management by efficient use of the available water both in the short-run and long-run perspectives. This includes drip irrigation and other improved water management practices.
Recognizing the importance of sustainable water-use efficiency inagriculture, has necessitated a number of demand management strategies,like water pricing, water user association and turnover system. Have been introduced since the late-1970s to increase the water-use efficiency, especially in the use of surface irrigation water.
One of the demand management mechanisms is the adoption of micro irrigation such as drip methods of irrigation. Evidences show that the water-use efficiency increases up to 100 per cent in a properly designed and managed drip irrigation system.
Drip method of irrigation helps to reduce the over-exploitation of groundwater that partly occurs because of inefficient use of water, under surface method of irrigation. Environmental problems associated with the surface method of irrigation like waterlogging and salinity are also completely absent under drip method of irrigation.
Amiran Kenya Drip irrigation method helps in saving of irrigation water, increases water-use efficiency and brings about high quality products. It also brings about increased crop yields and enhances efficiency in higher fertilizer-use.
Though the potential benefits generated by the drip irrigation methods are apparent, the adoption of drip irrigation is yet to be widely promoted across regions. It is found that the most ideal policy environment for promotion of micro irrigation technologies in the well-irrigated areas would be prorate pricing of electricity, which would create direct incentive for efficient water use.
Adoption of micro irrigation systems is likely to pick up fast in the arid and semi-arid, well-irrigated areas, where farmers have independent irrigation sources, and where groundwater is scarce. Further, large size of farm and individual plots, and a cropping system dominated by widely-spaced row crops, which are also high-valued, would provide the ideal environment for the same.
Evidences show that many researchers have attempted to study the impact of drip irrigation and have found that drip irrigation produces the desired positive impacts.
It is evidenced that the drip irrigation technology is technically feasible, particularly when the farmers depend on groundwater sources. Still, the studies on impacts of drip irrigation on the farming system as a whole are scanty and yet to be explored much.
In this context, drip irrigation has received much attention from policy makers and experts like Amiran Kenya, for its perceived ability to contribute significantly to groundwater resources development, agricultural productivity, economic growth, environmental sustainability and improving food security in a country.
Amiran drips are sourced from Netafim the world leader in offering efficient solutions for irrigation. This technology from Israel has managed surplus production for export to Africa and the rest of the world. At the moment Kenya is faced with serious challenges of food security and the economy of the country. Twelve out of forty seven counties are facing starvation. This is why there is need to ensure increased production and at the same time efficient use of water.
Benefits of Amiran’s Drip Irrigation.
- Maximum efficiency on water use during irrigation .Up to 75% reduction in the amount of water application per acre compared to furrow/flood irrigation.
- It is simple to install, operate and manage. It also saves on labor and time.
- Amiran supplies high quality drippers from the leader in drip technology Netafim ensures long term service of guaranteed minimum 10-20 years under good management.
- Affordability, the size depends on the farmer’s farm acreage. Recorded production increase has been realized as compared to other forms of irrigation.
- Specific placement of water drops right to the plant, reduces on water losses, high evaporation, weeds growth, leaching of nutrients, soil erosion, diseases and pest development and crop losses.
