Step 1: Understanding the Concept:
Drip (or micro) irrigation is an efficient irrigation method that applies water directly to the plant's root zone through a network of valves, pipes, tubing, and emitters.
This method minimizes water loss from evaporation and deep percolation.
Step 2: Detailed Explanation:
Let us review the historical contributions of the scientists listed:
- Simcha Blass (A): He was an Israeli water engineer who developed the first practical, plastic-emitter-based drip irrigation system.
In the late 1950s and early 1960s, Blass noticed a large tree growing exceptionally well without visible irrigation, which was due to a slow leak from a nearby water pipe.
This observation inspired him to design a plastic emitter device that utilized friction and long, winding pathways to slow water flow, delivering water drop-by-drop to the roots.
He patented this invention, which laid the foundation for Netafim, the pioneer of modern drip irrigation.
- Justus von Liebig (often referred to as Van Liebing in options) (C): A German chemist regarded as the father of organic chemistry and fertilizer industry. He formulated the "Law of the Minimum."
- C.W. Thornthwaite (D): A climatologist known for developing climatic classification systems based on evapotranspiration.
Therefore, Simcha Blass is the inventor of drip irrigation.
Step 3: Final Answer:
The inventor of drip irrigation is Simcha Blass.
