Wild asparagus in olive orchards - Get more income from your orchard

Why plant asparagus?

High yielding olive trees need plenty of light and need to be spaced apart. Hence both traditional and super-high-density orchards intercept no more than 50-55% of the sunlight. The rest will fall on the ground and encourage weeds. Why, then, not plant another crop you can sell under the trees, to use that light?
