Magnetized Water Irrigation Alleviates Emitter Clogging of a Drip Fertigation System

Drip fertigation systems are a new technology to alleviate water shortages and improve fertilizer use efficiency. Emitter clogging is the main obstacle their application. However, few efficient, safe, environmentally friendly methods available clogging. In this study, we explored effects of magnetized irrigation on emitter at different fertilization levels. Field experiments were conducted study patterns characteristics drip during two planting seasons. The results showed that with an increase in application, was aggravated. Magnetization treatment effectively relieved clogging, which increased average discharge variation rate (Dra) by 4.1–29.0% 2.6–64.4%, respectively, decreased dry weight (DW) substance 14.0–64.6% 15.0–75%, seasons, compared non-magnetization treatment. composition substances estimated using X-rays; quartz, silicate, carbonate dominant induced can reduce content thus possible mechanism Our demonstrated magnetization effective, chemical-free method great potential for control systems.
