Is Precision Conservation Practical?

I read an article in the Journal of Soil and Water Conservation today that proposed the premise that it is possible to grow and mange different crops in the same field for different purposes.The looked at Switchgrass and corn. Some of the corn was harvested for biomass as well as grain.  The switchgrass was harvested for biomass.  I see lots of barriers to implementation on a large scale, but it was interesting to see that it was even possible. Unfortunately, I can only share the abstract.
