Irrigation systems such as flood irrigation apply water at a faster rate in different soils which results in wastage of water through run-off and evaporation. The plants cannot fully utilize all the water since it saturates into the soil quickly. The application of large amounts of water can also result in leaching and water-logging. The rate at which water soaks into the soil depends is determined by the type of the soil. It is therefore important to identify the soil type and how it reacts with water before setting up a drip irrigation system. Since water is a scarce but valuable resource, it should be preserved. Water should be applied at different rates depending on the soil type.
In sandy soils, water moves quickly and goes deep into the soil. The wetting pattern is mainly vertical than horizontal in this soil type. When doing irrigation on sandy soils, higher flow drippers which are spaced closely should be used to ensure that plants receive sufficient water.
Since the soil is dense, the rate of water absorption in clay soil is quite slow. To prevent water from pooling on the surface, drippers should be set to apply water at a slow rate. This ensures that water gets to the roots and minimizes water loss. Water should be applied for longer periods to ensure that the plants receive enough water.
In loamy soils, water gets infiltrated into the soil at a slower rate compared to sandy soils but it gets evenly distributed, horizontally and vertically. Mid-ranger drippers and sprinklers can be a good choice for this type of soil.
Why Soil Testing is Important
Soil testing is important when determining the soil type. Regardless of whether you want to irrigate your nurseries, garden, orchard or your lawn, professional soil testing services will be essential to help you know the rate of irrigation and the drip irrigation kit to use.
