Israeli miracle in the Colombian desert
They said it couldn't be done, but a group of Israeli agricultural
experts have succeeded in helping local Colombian farmers grow potatoes
in a harsh desert environment.
"From this desert you might receive stones, but not potatoes," that's
what local farmers in Colombia's northern La Guajira desert said when
presented with an Israeli proposal to grow potatoes in the region.
A year later, Israeli know-how and technology has won the day, and
produced nothing short of a miracle as local farmers have harvested 11
tons of potatoes from the desert.
La Guajira is a coal-producing region, and the company that processes
most of that coal financed the potato project as a world-first
experiment to get the tubers to grow in a desert climate. Typically,
potatoes only grow in cooler climates where the soil has sufficient
moisture. The success in La Guajira is considered a world-first for
potato farming in dry, hot climates.
The project was the brain-child of Isaac Gilinski, a Colombian Jewish
businessman who is currently serving as Colombia's ambassador to
Israel.
The son of Israeli immigrants, Gilinski knew well of Israel's
agricultural prowess and, with the help of Israeli agricultural expert
Avi Nachmias, determined to bring that expertise to his country.
Nachmias and others trained local Colombian farmers and helped install
an Israeli irrigation system.
Officials from the Israeli Embassy in Bogota who visited the new La
Guajira potato farms said, "The locals were in shock over this miracle.
The farmers here are very conservative by nature, so it was not easy for
them to break old habits and try something new. But from their point of
view, this was a tremendous success, since a local potato harvest will
create a lot of new income."
Colombian officials are reportedly eager to repeat what they call the successful Israeli project in other parts of the country.

About drip Irrigation and installing drip irrigation system
What is drip irrigation
A Brief History of micro irrigation
Drip irrigation, sometimes referred to as micro irrigation or trickle irrigation, has its roots in agriculture. In many parts of the world with limited water supplies drip irrigation was one of the few options available for irrigation. Its development depended on advancements in polyethylene tubing, and its growth was most rapid in arid and drought-plagued regions. Beginning in the late 1960's farmers discovered that by using drip irrigation they could increase yields while lowering water use. The 80's saw drip irrigation making the transition into commercial landscape, with mixed success; in today's market, however, drip irrigation is well trusted and used extensively in agriculture, and is actively utilized in commercial landscape and residential garden sites, providing a possible solution to some of our water management problems.
What is Drip Irrigation?
Drip irrigation is the slow, precise application of water and nutrients directly to the plants' root zones in a predetermined pattern using a point source. A drip irrigation, micro irrigation or trickle irrigation design can be customized to meet specific needs while maintaining an optimum moisture level within the root zones, efficiently conserving water that might otherwise be lost to non-growth areas, runoff, sun or wind, and providing the proper balance of water and air needed for successful plant growth. These benefits can be useful for any residential, commercial or agricultural installation, and may be critical for cities and municipalities that face water restrictions while aspiring to maintain or expand their green areas.
At the present time and as long as water is inexpensive, irrigation inefficiency and over-watering may be overlooked. Once water supply is low due to a drought and water restrictions are applied, the inefficiencies of a poorly designed and installed irrigation system quickly become apparent. For an irrigation system to be successful, it must include proper design, correct installation, the right component selection, the proper layout, and equally important, appropriate maintenance. One of the main advantages of drip irrigation systems over conventional irrigation systems is the flexibility to adapt to any layout above or below grade, in any location. This feature allows users and installers to customize an irrigation system to meet a specific need for a wide range of irrigation requirements.
Unlike drippers or drip emitters, "micro sprinklers" throw the water over a wide area, and are designed to be used in areas where drip emitters are not practical, such as large areas of groundcover and flowerbeds. Micro sprinklers offer many of the same benefits as drip emitters. Using low volume irrigation offers key advantages and benefits to both contractors and homeowners.
Conventional irrigation systems using sprinklers or bubblers are rated in gallons per minute (GPM). Drip irrigation, micro irrigation or trickle irrigationflow rates are in gallons per hour (GPH), such as 1 GPH or 2 GPH drip emitters. For example a popup sprinkler used on a lawn may be rated at 1 to 3 GPM (gallons per minute), or 60 to 180 GPH (gallons per hour) while drip emitters are rated at 1-4 GPH (gallon per hour) and micro sprinklers may be rated from 5 to 45 GPH (gallons per hour).
With conventional watering systems, water may be lost through runoff, low system uniformity and high rate of evaporation, blown away by wind or wasted on non-growth areas. Using drip irrigation water is absorbed slowly into the soil and directly into the root zone. No water is wasted on non-growth areas. By placing the drip emitters just at the plant root zone you can water using much less water and with better efficiency. This irrigation method allows the water to move deeper into the soil, encouraging deeper root growth. In addition, the low flow of drip system enables watering of large areas using a single water source.
Another advantage of using a low flow drip irrigation system is that high pressure is not required to supply water to the drippers and micro sprinklers. Most drip systems operate at about 15 to 30 PSI (pounds per square inch), while the average home has water pressures of anywhere from 40 PSI to 80 PSI. Consequently, with a drip system, you will not notice a drop in pressure when the system is operating.
Also, operating under low pressure allows drip irrigation systems to use drip tubing, drip emitters, drip fittings and other components that do not require glue, clamps or hard-to-connect components. In fact, most components of a drip system can be moved or reused. This is explained in more depth in other sections.
Advantages and Benefits of Drip Irrigation System
-
Water Efficiency:
By applying water only where and when it is needed, with less runoff and less evaporation from leaves and soil, the uniform application of water from drip irrigation systems can achieve high water savings. -
Ease of Installation:
The system can be installed without special tools or glue, and with limited knowledge, making the installation a very simple process. -
Reduced Pest Problems and Weed Growth:
Watering only the roots of your plants with drip irrigation cuts down on water-borne pests and fungal diseases that spread by water movement, as well as the germination of weeds in the area between your plants. -
Versatility:
Low volume irrigation systems are designed for placement in both new and existing landscape areas, and are ideal for installation on difficult terrain such as on slopes, in oddly shaped areas, and on windy sites. -
Root Zone:
One benefit of a drip irrigation system is the creation of a totally new and more favorable root zone environment because of the maintenance of a relatively constant soil moisture level. This has important implications for plant water requirements, tolerance and control of disease. -
Economy:
Investing in a low volume irrigation system can save you money and significantly lower your water use.
Disadvantages of Drip Irrigation
No serious introduction to drip irrigation would be complete without a look at the disadvantages associated with its use:
- The drip tubing can be susceptible to damage from rodents, and household pets.
- A filter is required to guard against potential clogging of the small water passages of the drip emitters and micro sprinklers.
- You cannot see a drip system working as you can see a conventional sprinkler system.
- Each drip emitter creates a wetted area around each plant, so watering is more critical in replacing the water used by the plant to avoid stress.
There are other details about drip irrigation that make it the sensible way to water your landscape area. Here we have provided only a broad overview. To see all the details scroll back up to our main help menu and check out the other sections.

Strawberry fields and onions
Sunday, March 11, 2012
UP IN Barangay Baganihan in Marilog District in the uplands of Davao City, a group of farmers are being introduced to new varieties of strawberries as the City Agriculturist’s Office (CAO) envisions the development of high-value crops producing area in the city’s biggest administrative district that can equal if not be better than the farmlands of Benguet.
For so long, the cool farmlands of Marilog have been producing strawberries, but the planting materials were of varieties that produce very sour fruits. Thus, the strawberries of Marilog never made it into the mainstream market.
The Baganihan Agri-Ventures Cooperative Inc. made up of farmers in the area have agreed to try out the project with the help of CAO and the high-value crops division of the Department of Agriculture (DA).
“We are targeting that around October of this year, Marilog will already be producing strawberries that can satisfy the local demand so that supermarkets here need no longer get their supplies from Benguet,” CAO officer-in-charge Leonardo R. Avila III said in a media tour of the experimental farm.
The varieties – Festival and Sweet Charlie – that BAVC is planting these days are those from Benguet, the red luscious strawberries that are sold in supermarkets here.
The farm is being manned by Criselda Iroy, who said, no one among the members have taken up interest on the experiment and that she has been farming anyway and so she took on the task.
Farther up the mountain highway in barangay Buda, another group of farmers are venturing into onion bulbs.
“We can produce these onions here, but we are importing most of these from China,” Avila said.
Jimmy Bangonan, 42, is the first to test the Rushmore and Red Pinoy varieties in a ¼ hectare farm lot.
With an initial capital of P9,000 covering seeds and land preparation, he said, he was able to net P42,000 in his first harvest of Rushmore onions. Seeds, he said, cost P320 per 100 grams and one needs around 1.4 kilos of seeds for ¼ hectare, Bangonan said.
“There are many buyers, they are the ones who come over and bought my harvest,” he said.
“Demand for onion bulbs will always be there,” Bangonan said in the vernacular. “Even the poor come over here in Buda to buy onions.”
His first harvest, he said, was that of Rushmore, and he finds this very profitable. From the seedbed, which has to be tended for one month, these are planted in the regular plots and made to grow for 75 days. After that, he said, he just keeps on harvesting every week.
He already planted a small plot with the Red Pinoy variety and found potential in this too, although the Red Pinoy takes longer to grow to harvestable age – three months or 90 days.
“But the bulbs are firmer and can be stored longer. You can also harvest more per plot,” he added. Four hundred grams of Red Pinoy seeds cost P1,400.
He appreciates the help CAO has extended in terms of access to seeds and technical support saying that before CAO came in, he was farming on his own without much access to better varieties that he could have earned more from.
To further help the farmers establish a market hold, the CAO is building a display center along the highway in Baganihan. The center will not only be a place where buyers can congregate but will also display the crafts of lumads in the area – mostly Matigsalugs.
Avila said the main problem of the farmers in the uplands is really access to planting materials and the market, this is what the CAO is opening to them. With such support, he foresees a huge potential for the city’s farm sector.
“The land is rich, the climate is suited for agriculture, there is vast potential in this area,” Avila said.
