Thank This Jew For Inventing Drip Irrigation



On these hottest days of summer – especially when parts of our country are rationing water – we should thank late Israeli engineer Simcha Blass for helping farmers figure out how to best harness the water they do have.

Blass revolutionized drip irrigation in the early 1930’s, pretty haphazardly. As the story goes, Blass saw a big tree growing seemingly without water. When he dug into the soil, he found an onion-shaped pocket of underground water feeding the tree’s roots. Each drop of water was being stored and sucked out as needed.

Blass made tubing that would release water slowly and steadily through larger and longer passageways, using friction to keep the flow. Blass refined this method and patented his surface drip irrigation emitter. In 1965, Kibbutz Hatzerim used Blass’s creation to create a new irrigation development industry, called Netafim, Hebrew for “droplets.”

Today, with Blass as inspiration, Israel continues to lead the way in drip and micro-irrigation inventions. These new products help farmers all over the world, no matter how arid the soil or how slow the water pressure.

It’s also a great lesson in human ingenuity and patience. Each water drop (and every kind action) makes a difference in the life and growth of our world.
