Effect of soil type on irrigation efficiency of atomized micro-sprinkler irrigation

In recent years, with the development of agricultural science and technology, atomized micro-sprinkler irrigation, as a new irrigation technology, has been favored by more and more farmers. However, soil type is often overlooked as one of the important factors affecting irrigation efficiency. So, what impact does soil type have on the irrigation efficiency of atomized micro-sprinkler irrigation?
First, soil texture is a key factor affecting irrigation efficiency. Sandy soil has good water permeability but poor water retention capacity, so when using mist micro-sprinkler irrigation, higher irrigation frequency and smaller droplet size are required to avoid runoff loss of water and deep seepage. In contrast, clayey soils have poor water permeability but high water retention capacity and therefore require lower irrigation frequency and larger droplet sizes to avoid overwetting and anaerobic soil conditions. Loam soil is somewhere in between, and is suitable for medium irrigation frequency and water droplet size to achieve high irrigation efficiency.
Secondly, soil structure will also affect the efficiency of atomized micro-sprinkler irrigation. Soil with a granular structure has good porosity and air permeability, which is conducive to water penetration and root development. Therefore, the use of atomized micro-sprinkler irrigation in soil with a granular structure can improve irrigation efficiency and reduce runoff losses. On the contrary, soil with a compacted structure has poor porosity and poor air permeability, which will lead to reduced irrigation efficiency and prone to runoff losses.
Finally, the organic matter content of the soil also affects irrigation efficiency. Soils with high organic matter content have better water retention capacity and aggregate stability, so using atomized micro-sprinkler irrigation in such soils can reduce irrigation frequency and improve irrigation efficiency. On the contrary, soil with low organic matter content has poor water retention capacity and poor aggregate stability, requiring higher irrigation frequency to avoid soil drought.
