Introduction to Drip Irrigation
Drip irrigation, also known as micro-irrigation or trickle irrigation, is an ingenious and efficient way to water plants. At some point, people in Pakistan refer to Drip Irrigation as Drop Irrigation. Unlike traditional sprinkler systems that spray water over a wide area, drip irrigation delivers water drop by drop directly to the plant’s root zone. This targeted approach ensures that each plant receives just the right amount of water, minimizing waste and maximizing plant health.
By using special tubes or pipes with tiny holes near each plant, Drip irrigation allows water to slowly and evenly drip into the soil, mimicking nature’s way of hydration. This not only saves water but also promotes optimal plant growth. Whether you have a garden, farm, or city landscape, drip irrigation can be customized to suit your needs, making it a versatile and environmentally friendly solution. Experience the magic of drip irrigation as we delve into its benefits and explore how it can revolutionize how we care for plants and protect our precious resources.
Types of Drop Irrigation
Drop-by-drop irrigation systems are available in two types: subsurface drip irrigation and surface drip irrigation. Let’s examine each type more closely.
Subsurface Drip Irrigation
Subsurface drip irrigation (SDI) involves burying narrow tubes at a 20-50 cm depth to prevent interference on the soil surface.
These tubes can be either porous or non-porous.
- Porous Tubes: These tubes continuously release water into the soil.
- Non-Porous Tubes: These tubes have emitters that release water at specific points. SDI is commonly used in fruit tree plantations and perennial crops.
Surface Drip Irrigation
Surface drip irrigation is a drip irrigation system that is installed above the soil surface. It utilizes emitters or drippers to regulate the flow rate and amount of water.
Drip Line Tubing and Drip Tape:
Emitters and drippers can be connected using drip line tubing or drip tape. Drip tape is a thinner tubing option that is quicker and easier to install but less permanent. On the other hand, drip line pipes are thicker and more durable, capable of withstanding higher water pressure.
Types of Surface Drip Irrigation Emitters:
- Point-Source Emitters (Drip Bubbler): These emitters are inserted into the tubes.
- In-Line Drip Emitters: These emitters are joined to the lateral supply tubes.
- Basin Bubblers: Basin bubblers utilize a round or square basin around the plant, concentrating and delivering water to that specific plant.
- Micro Spray Sprinkler: This type of emitter rotates to cover larger areas.
