Agriculture sprinkler irrigation systems

Water is the lifeline of agriculture, and efficient irrigation is essential for maximizing crop yields while conserving resources. One of the most effective and widely used methods is Sprinkler Irrigation, which distributes water evenly across fields, mimicking natural rainfall. There are several types of agricultural sprinkler systems, each designed to meet specific needs based on crop type, field size, and water availability. Whether for large-scale farms, orchards, or delicate crops, choosing the right sprinkler system ensures optimal water distribution and improved efficiency. In this article, we will explore the main types of sprinkler irrigation systems and their best use cases.

Types of Agriculture Sprinkler Irrigation Systems

1. Open field sprinkler irrigation

Open-field sprinkler irrigation is commonly used for vegetables and annual crops, providing full coverage across large, flat fields. This system ensures even water distribution, promoting uniform crop growth and maximizing yield. Water is delivered in droplets that mimic rainfall, with adjustable settings to suit different crop types and growth stages. Key to its efficiency is uniform water distribution (measured by Christiansen’s Uniformity Coefficient, CU), a low precipitation rate (3-5 mm/h) to minimize runoff, and precise overlap patterns to maintain a uniform wetted profile.

4. Full Coverage Under-Canopy Irrigation

Full coverage under-canopy irrigation uses low-angle sprinklers or drip systems placed beneath the canopy to deliver uniform water distribution directly to the root zone and soil. This method avoids foliage wetting, maintaining healthy crop growth while promoting consistent soil moisture. It reduces plant stress and allows efficient application of fertilizers and chemicals. With a low precipitation rate of 3-5 mm/h, evaporation loss is minimized, ensuring better water retention and overall plant health, leading to improved crop development and yield. This method promotes larger root exploration and ensures water is delivered precisely where it’s needed—at the roots. This system can also provide an indirect frost mitigation effect thank to the latent heat due to frozen water in the soil
