1. Choose according to soil characteristics:
• Soil texture:
- Sandy soil: Sandy soil has strong water permeability and poor water retention. It is necessary to choose a sprinkler with low sprinkler intensity and small water droplets to avoid excessive water infiltration and loss. For example, you can choose Nielsen's R3000 rotary sprinkler, which has low rainfall intensity, can reduce water loss, and has a large spray range, which is conducive to uniform irrigation.
- Loam: Loam has a moderate texture, with certain water retention and air permeability. You can choose a sprinkler with moderate sprinkler intensity and a more appropriate spray range. Like Nielsen's A3000 rotary sprinkler, it has a better low-pressure effect, high uniformity, and low rainfall intensity, which is suitable for loam irrigation.
- Clay: Clay has poor water permeability and is prone to water accumulation. You should choose a sprinkler with low sprinkler intensity, small water droplets, and not easy to produce surface runoff. Nielsen's S3000 rotary sprinkler is a good choice. Its water droplets are small and have little impact on the soil, which is conducive to the infiltration of water into clay soil, and will not wash the seeds and affect germination.
- Soil infiltration rate: For soils with high infiltration rate, you can choose sprinklers with large flow and long range to ensure that water can fully penetrate into the soil; for soils with low infiltration rate, you should choose sprinklers with small flow and low sprinkler intensity to prevent surface runoff and water accumulation.
