Also look around for those ditch apples mentioned by Matt, they will give you a clue as to how well yours will work out.
Took a lot of observation to figure out apples don’t work well at our elevation. Too hot and too much disease. Cedar apple rust will completely defoliate them, not quite kill them, but just keep them weak enough to where they don’t grow or produce well without management. Just a little further up in elevation I start to see ditch apples that produce with no care at all. You are probably near that line.
Rocky soil also helps deter voles which love soft loam. You might mix in some gravel when you backfill your holes, a tip I got from a local grower. I also planted daffodils around them as some said that helps.

He wants $5 for a 14" x 18" X 36" bale. If I did my math right to covert the 14" x 36" or ~500/144 sq-in or 3.5 sq-ft. That's $5/3.5 or ~ $1.50 sq-ft. That's 3X fibergass ($.50 sq-ft) or mineral wool (roxul) $.70 sq-ft both @ R-15.
What is the r-value of this stuff for codes and certification (energystar, LEED, etc) ?
Gathering this info myself now. Per this, R-value for straw bales is 26-30 for an 18" thickness. So based on your comparison, it's about twice the R-value and twice the cost of Roxul (aside from 4x the wall thickness). So almost equivalent except that you have to factor in the lumber cost saved and also the actual lesser R-value in the Roxul scenario due to the wood framing. Still, personally I don't see a compelling reason to go with straw bale yet ... If anyone has info or links that would help me understand why straw bales might be more economical, I would appreciate it. (I understand it is more eco-friendly)
"Testing for R-value has been conducted several times. Only a few tests of full-scale walls (rather than bales) have been conducted (by Oak Ridge National Labs and the Technical University, TUNS, of Nova Scotia). The R-value for these walls were found to be between 26 and 30, about double that which can be expected from a wall built to most code requirements. (Note that a 2x6 wood frame wall with R-20 batts has an R-value of about R-13 when the thermal bridging through the studs is considered). Strawbales are comprised of over 90% air voids, easily connected to one another." https://buildingscience.com/documents/digests/bsd-112-building-science-for-strawbale-buildings
