[Worldkings] Top 50 inventions and discoveries made by accident (P. 20) Simcha Blass found out the principle of drip irrigation thanks to a leaky water pipe


(Kyluc.vn - Worldkings.org) From an accidental discovery, Simcha Blass invented the drip irrigation system, revolutionizing agriculture in arid and semi-arid regions.

Simcha Blass (November 27, 1897 – July 18, 1982) is probably one of the most well-known names in the discovery of drip irrigation. Although the technique was being tested at primitive levels in Germany during the 1920’s, it is widely known that Blass, Jewish inventor and chief water engineer of Israel in the 1930’s, developed this method that saw great results.


Strangely enough, this discovery was made almost accidentally. While spending time in the desert regions of southern Israel, Blass noticed that one tree near his location seemed to be prospering better that all the other nearby foliage. Upon closer investigation, Simcha discovered that a water pipe near this tree had sprung a small leak—dripping regular water onto its root system, allowing it to flourish.

This sight of tiny drops penetrating the soil causing the growth of a giant tree provided the catalyst for Blass's invention. The drip irrigation concept was born and experiments that followed led Blass to create an irrigation device that used friction and water pressure loss to leak drops of water at regular intervals. Recognizing the high potential of his discovery, he began to look for ways to turn his idea into a product.


It wasn’t until the 1950’s, when the development of modern plastics was being discovered, that Simcha Blass was able to take his new product to the next level. However, the greater test to his scientific know how would be refining the friction and water pressure process that was needed to create a healthy flow of water that both nourished the plant and conserved water. In the early 1960s, Blass developed and patented this method and founded the Netafim company to manufacture and market the system.

Today, drip irrigation is used around the world and has helped to make agriculture more sustainable and efficient, particularly in dry regions where water is scarce. Blass's invention has been credited with increasing crop yields, reducing water waste, and improving the livelihoods of farmers.
