People of all ages enjoy the benefits of gardening, ranging from producing high quality produce to working with the soil. Due to water costs, and increasing water demands, gardeners need to be concerned about conservation. One effective way to conserve water is by utilizing drip irrigation.
Drip irrigation is a method which reduces the use of water by allowing water to drip slowly to the roots of plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters. There are many advantages of using drip irrigation. These include:
– Water savings, since only those areas directly around plant root zones are irrigated.
-Plants undergo less stress from variations in soil moisture.
– Slow application rate prevents excess surface water build-up and reduces evaporation.
-Weed growth is reduced because areas between plants are not irrigated.
-System can be designed for use in all types of terrain and soil conditions.
-Low flow rate allows irrigation of larger areas and more plants can be watered at once.
These and other benefits are only possible to the user when a drip irrigation system is properly designed, managed, and maintained.
Gardeners in Juab County designed a drip irrigation system that is simple, user friendly, easy to manage, and effective. The system can be designed to accommodate nearly every type of garden situation. People should design a system that works best for them. The Juab County Drip Irrigation System can be modified for different types of applications including raised beds, greenhouses, fruit trees, and traditional gardens.
The system uses ½, ¾, or 1 inch PVC pipe, fittings, and manual valves. Depending on care, life expectancy of the materials is 10 to 12 years. All lines and fittings, before the manual valves, are glued to handle high water pressure. Lateral lines are not glued to make the system flexible in row placement. Lateral lines can be changed and moved quite easily depending on the type of plants grown.
VALVES, WATER OUTPUT, PLUGS, AND END CAPS
One problem gardeners experience with their irrigation system is controlling flow rate and high water pressure. With this system, manual ball valves are used to control flow rate and assist in reducing pressure. The number of lateral lines that can be used with this system will vary a great deal. It will depend on several factors including the irrigation source flow rate and pressure, length of main and lateral lines, and the desired per hole water output. As gardeners use this system, they will learn how to manage their system to maximize water output.
Plugs are used to eliminate water flow in nonirrigated row areas. End caps are used on the end of each lateral line to force the water through irrigation holes. The caps are not glued for the ease of cleaning the system.
Hole size is one of the keys to the success of the system. A 1/16 inch hole is the desired size. It is large enough to let soil particles pass through, but small enough for correct flow rate. To drill the holes in the lateral lines, the following equipment is needed: drill, tape measure, marking pen, and 1/16 inch drill bit. For convenience when drilling holes, place the pipe on some type of stand, such as tables placed end to end.
Lateral irrigation lines and individual hole spacing will depend on the users garden plan for the current year. For plants such as corn, carrots, and peas, the holes are spaced every 6 inches. For plants such as watermelons, tomatoes, and pumpkins, the holes are spaced in groups of three, 2 to 3 inches apart. The spacing for each plant group can vary between 3 and 5 feet. This will depend on the suggested plant spacing requirements.
One of the essential elements of a successful garden is being able to meet the nutrient requirements of the plants during the season. The first step in creating fertile garden soil is to determine current nutrient needs. Soil testing information is available at your local Extension office. There are different types of fertilizers available to the home gardener. These include both chemical and organic fertilizers. There are also different methods of applying fertilizers including injectors, foliar feeding, side dressing, banding, and broadcasting. The Juab County Drip Irrigation System can be used with most application methods, but the best results will be achieved by using some type of injector. Injectors can use either dry or liquid water-soluble fertilizer. By using an injector with this drip system, a gardener can control the quantity of fertilizer applied to meet the nutrient requirements of the different plants.
Before planting, the entire system should be laid out and tested, which involves flushing out the main line and laterals with water, end caps removed. Next, install all end caps, and with the holes facing up, turn on the water and clean out any plugged hole with a piece of wire. After testing the system, the holes can be turned up or down. For lateral lines with holes facing up, drill a drainage hole on the bottom every 2 to 3 feet.
For the best results in using this system, the ground should be level. To compensate for non-level ground, using items like leveling stakes installed at different heights and intervals will help make the lateral lines as level as possible.
By using this system, users will enjoy several benefits. Water savings: in different studies, home owners noticed water savings of up to 75%. Time savings: in the same studies, the participants experienced up to 90% time savings in watering and weeding the gardens.
Throughout the growing season, the study participants observed that the plants were healthier and produced at a higher level.
Drip irrigation can help home gardeners enjoy the benefits of gardening. By using drip irrigation, gardeners will spend less time weeding and watering, will notice water savings, and enjoy higher production. The Juab County Drip Irrigation System is simple to design, user friendly, and highly effective. Using this system can add to the enjoyment and satisfaction of raising gardens.
