Drip Irrigation Systems
Using Eco Bag as Drip Irrigation
Drip irrigation exceeds 90 percent efficiency whereas sprinkler systems are 50 to 70 percent efficient. It is so efficient that many water utilities exempt landscapes irrigated with drip from restrictions during drought. Note that any irrigation system is only as efficient as the watering schedule used. If systems are set to water excessively, any system including drip can waste water.
Low volume application of water to plant roots maintains a desirable balance of air and water in the soil. Plants grow better with this favorable air-water balance and even soil moisture. Water is applied frequently at low flow rates with the goal of applying only the water plants need. Sprinkler irrigation results in a greater wet-to-dry fluctuation in the soil and may not produce optimal growth results.
Drip irrigation delivers water slowly immediately above, on or below the surface of the soil. This minimizes water loss due to runoff, wind and evaporation. Drip irrigation can be operated during the windy periods frequently seen in Colorado.
The mold spots on house siding and the staining and deterioration of wood privacy fences experienced with overspray from sprinkler irrigation is eliminated with the use of drip. Because water doesn’t leave the landscape with drip irrigation, pavement deterioration associated with sprinkler irrigation runoff is eliminated.
Properties with old, galvanized steel water service lines where corrosion has resulted in a narrowed diameter may benefit from a retrofit to drip irrigation. The low volume requirements of drip irrigation are a good match with restricted supply lines.
Drip systems can be managed with an AC or battery powered controller. Automated landscape irrigation is an advantage to many people with busy lifestyles.
Adaptable and changeable over time, drip systems can be easily expanded to irrigate additional plants if water is available. Emitters can be simply exchanged or removed and emitter lines eliminated or repositioned. When plants are removed or die, drip lines should be plugged..
If emitters are poorly placed, too far apart or too few in number, root development may be restricted by the limited soil area wetted. Water seeping at ground level is hard to see and makes it difficult to know if the system is working properly. An indicator device that raises and lowers a flag to show when water is flowing is available to overcome this issue.
Regular maintenance inspections are needed to maintain system effectiveness—the same as with high pressure sprinkler systems. Clogs are much less likely with filtered water and proper pressure regulation used in combination with self-cleaning emitters.
Drip tubing can be a trip hazard especially for dogs and children but is less problematic if covered with mulch and fastened with wire anchor pins every 2 to 3 feet. Drip lines can also be easily cut while undertaking other landscape maintenance activities.
Eco-bag is fillable bag that mount around the base of a rose or plant and slowly releases water as the plant requires it. No battery or electricity required for this tree watering bags
