4 Irrigation Systems in Horticulture: Choosing the Right Method

Sep 27, 2023 4:50:49 PM

The method of watering plays a crucial role in the quality of your crops. It affects logistics, labor, overall costs, and the constant high quality of your plants. Therefore, selecting the appropriate irrigation method(s) is essential. This article will discuss four ways to provide plants with water.

#1 Advantages and Disadvantages of Drip Irrigation for greenhouses

Drip irrigation ensures that each plant receives the precise amount of water through a small emitter, minimizing water wastage. Additionally, it keeps the plant foliage dry, reducing the risk of diseases.

However, there are drawbacks to this method. It is labor-intensive since each plant requires its own emitter, which must be removed from the pots at harvest. These small emitters can also become clogged easily. Moreover, it restricts you to a particular pot size as the drip irrigation system is designed accordingly.

Drip irrigation can also complicate the automation of internal logistics, and it encourages root growth primarily where water drips, potentially making the plant less resilient.

#2 Advantages and Disadvantages of Sprinkler Irrigation

Many greenhouses or outdoor fields use sprinklers, often a cost-effective method suitable for various crops.

The effectiveness of this method depends on whether excess water is collected. Without proper drainage, excess water can puddle, causing root damage, excess runoff, and the loss of valuable nutrients. Additional heating might be required during wet periods to prevent overly humid greenhouse conditions, resulting in increased energy costs.

Sprinkler irrigation can also increase the risk of diseases in flowering plants when the foliage becomes wet. Also, large leaves can redirect water away from the plant's roots, leading to uneven water distribution. Wind can also affect the sprinkler pattern, causing water to go in different directions, causing uneven coverage, and some plants may receive less water, leading to uneven water distribution.

#3 Advantages and Disadvantages of Water Boom Irrigation

Boom or spray booms provide precise watering, ensuring uniform hydration for all plants, with the flexibility to provide extra water to specific areas. Wind has minimal impact because boom irrigation systems get close to the plants. This method also lends itself well to production automation.
However, this method tends to be relatively expensive. Like sprinkler irrigation, it can wet flowering plants, increasing the risk of diseases. The importance of capturing water and valuable nutrients applies here as well.

#4 Advantages and Disadvantages of the Ebb and Flow System

Watering using an Ebb and Flow System can be achieved in various ways, such as flood-and-drain concrete floors, flood-and-drain tables, and the ErfGoedFloor (cultivation floor). In all cases, water rises from below and drains away after watering.

A significant distinction between the ErfGoedFloor and other Ebb and Flow systems lies in how the water rises. With the ErfGoedFloor, the floor fills evenly with water in the stone layer before rising above the ground cover. This results in uniform water distribution, promoting consistent plant growth. Further details about the pros and cons of various Ebb and Flow systems can be found in this whitepaper.

Combining Irrigation Systems

You can choose to combine multiple irrigation systems. We recommend starting with overhead irrigation for plugs, seedlings, and cuttings. Subsequently, transitioning to an ebb-and-flow floor is advisable, as the plant's roots will have developed sufficiently to absorb water from below. Under these circumstances, bottom-up watering becomes preferable.

Far-Reaching Consequences

As mentioned earlier, choosing an irrigation system has far-reaching consequences for your labor, logistics, potting soil, pots, and more. Sometimes, combining methods can lead to optimal results.
