Abstract
This study was performed to investigate the uniformity of distribution of water and discharge variations in drip irrigation using magnetic water. Magnetic water was achieved by transition of water using a robust permanent magnet connected to a feed pipeline. Two main factors including magnetic and non-magnetic water and three sub-factor of salt concentration including well water, addition of 150 and 300 mg L−1 calcium carbonate to irrigation water with three replications were applied. The result of magnetic water on average dripper discharge was significant at (P ≤ 0.05). At the final irrigation, the average dripper discharge and distribution uniformity were higher for the magnetic water compared to the non-magnetic water. The magnetic water showed a significant effect (P ≤ 0.01) on distribution uniformity of drippers. At the first irrigation, the water distribution uniformity was almost the same for both the magnetic water and the non-magnetic water. The use of magnetic water for drip irrigation is recommended to achieve higher uniformity.
Highlights
Due to the shortage of water resources, the use of available water and use of unusual water is the main objective in agriculture
The highest electrical conductivity (EC) belonged to the water salinity of 300 mg L−1 calcium carbonate treatment (Table 3)
When the carbonate and calcium ions come into the area that is swayed by the magnets, they are pushed in opposed ways, due to their opposed charges
Summary
Due to the shortage of water resources, the use of available water and use of unusual water is the main objective in agriculture. Increasing population, higher profitable activity and upgraded standards have led to an increase in wars over the freshwater resources. It needs to provide additional land for farming to increase food production in order to support the acceleration of population growth to use all sources of low-quality water. Melo et al (2008) investigated the effects of magnesium and calcium carbonates on dripper clogging and water uniformity distribution in drip irrigation. They showed that the dripper clogging reduced the water uniformity distribution and increased the variation coefficient of drippers. They showed that the dripper clogging reduced the water uniformity distribution and increased the variation coefficient of drippers. Han et al (2017) investigated the lateral flushing on the dripper clogging and showed that the coefficient of uniformity of drippers was increased from 11.6 to 67.4% compared with non-flushed treatment
