I suggested concrete to save time collecting rocks.
But time does not seem to be an issue when I see plans for a tremmel to sift rocks and the abundance of them.
What will you cart the rocks with and would you hand load them or use a loader.
Would you be able to collect rainfall and use it, my signature has some details?
Rammed earth is easier with a bot cat style of loader to lift soil and shift the boxing required.
Also a large compressor and air rammer saves time over a simple tamper, would you be going all hand
operation or use some mechanical assistance.

Given that you are a design engineer and you have the freedom to examine ideas beyond Cochise County, I'm guessing that you might find New Mexico's Earthen Buildings Materials Code useful as a data point for your inquiry. Yes, the code does specify some concrete for the grade beam that is built atop the rubble trench:
"Concrete grade beam. Rubble filled foundation trench designs with a reinforced concrete grade beam above are allowed to support rammed earth wall construction. An architect or engineer registered in the state of New Mexico shall certify the grade beam/rubble-filled trench design portion.

You plan to build a house but cannot fund the foundations?
Something is all wrong about this plan?
Either;
- house too big
- importance of foundations not accepted
