You are correct, Potassium is what is missing from our soil here.
The other problem is the wind, you cannot get compost or mulch to stay around, it all blows away.
So we have to garden in an enclosed area, solar greenhouse being the best solution.
Thanks for the suggestion, I had forgotten the name.
I am glad you came to read the thread and offer a good suggestion to our readers, hope you will often.

All you can do right now is go out there with a shovel and turn dirt over and add everything in it and mix it up. Then add water to turn it into mud so everything mixes together.
Next spring, plant whatever you want there. Those cold desert winds are bone-chilling and relentless. Most people don't know that deserts get very cold, with freeways shut down with snow and ice and flash floods.
