In the early 1950s, on our family farms in New South Whales we developed a system of farm management we called “Keyline”. My father was the genius behind the whole concept. He was a geologist and mining engineer originally and turned this expertise onto the problems of water storage and handling for on-farm water storage and low cost irrigation. He understood insightfully the role for the enhancement of soil fertility in all forms of farm management. My role was in equipment design, and i did think up the name “Keyline” to describe it all.
