It’s strange that the article you linked doesn’t mention no-till farming. Farmers replace the plows on their tractors (which turn over the soil) with knives that have fertilizer injectors on the tips. Rather than plow, then spray fertilizer on to the surface, they inject fertilizer into the ground. After a few years, earthworms reestablish themselves and naturally aerate the soil.

This can be combined with other (well established, commercially available) precision agriculture techniques to minimize irrigation and fertilizer waste.

The big problem is the up front cost of replacing tractor implements, and training labor.

Anyway, this is much easier than agroforestry, building glass hydroponics towers, etc.
