Seems kind of weird that California, which is usually on the cutting edge, is adopting old techniques from the Midwest. First conservation tillage, now center-pivot sprinklers.

One other reason why center pivot may not have caught on in California is that land is more at a premium here than in the midwest or Nevada desert (another common place to see center pivots). It is just a mathematical fact that circles don't make the best use of land in terms of area planted on rectangular parcels. Center pivot will catch on only if water becomes scarce to the point that the reduction in planting due to poor land utilization from center pivot is less than the reduction in planting due to the decreased water supplies. And that's barring any future developments in irrigation that might allow the more efficient use of water on rectangular fields.

That's interesting that center picots helps with the conservation of tillage and keeps the residue soil more porous which allows for quicker water absorption. This would be beneficial for farmers in desert areas since it would help the plants absorb more water so they wouldn't have to use as much for the plants to work. It's interesting that putting crops in a circle with a pivot in the middle can change the way the soil absorbs water.
