Understanding Keyline Design : Part 3
Darren suggested I include a couple of images of an olive grove that he designed for our farm. This provides a good example of the principles of keyline design. Pictured below is Darren’s original layout for the olive grove. In designing this grove, he performed a half meter contour survey represented by the solid black lines in the photo below.

As you can see in this example of keyline design, the tree lines don’t follow the contour lines precisely. Instead they cross the contour lines which reflects the principle of allowing water to fall from the gullies to the ridges. 
The olives has thus been able to establish themselves without irrigation, even during several years of extreme drought.
The trees have also demonstrated even and consistent growth which reinforces the benefits of keyine design.
Pictured here is a satellite photograph of the grove following ground preparation and below the olives as they appear today.




Nina and I are dedicated to achieving our personal self-sufficiency, and an important part of this is the milking of our jersey cow.
