How about this? Just get a pound of potassium nitrate and mix it with your soil. Anything you want will grow. Like tomatoes the size of softballs. Over in Ventura the managers of those farms use a whole lot of ammonium nitrate. Dont use that. Use potassium nitrate in the soil. You will have great big veggies. One tomato will fill you up with a little hot sauce and pepper.
potassium nitrate<<<
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.
