Drip Irrigation

Drip irrigation is one of the smartest tools farmers have today—it saves water, reduces waste, and delivers moisture directly to plant roots. But there’s one stubborn problem that keeps holding it back: clogging.

The emitters in drip systems are tiny—only 0.5 to 1.2 mm wide—making them very easy to block. Sediment, salts, and microbial growth can quickly plug them up, lowering efficiency and forcing farmers to spend more time and money on maintenance.

A new review by Abdul Rahim Junejo, Jinrui Liu, and colleagues highlights a game-changing technology that could solve this problem with nanobubbles.
