While I continue my ongoing research, reading journals here and elsewhere, I have found no one who has used just plain old soil from the ground. I live a little south of Fairbanks, and Alaska is known for its rich soil. I have decided to take a risk and use home grown soil, not only as an experiment, but funds do not allow me to buy and ship 1.5 cubic inches of soil up here. I did buy FF trio nutes. John, have you heard of any success or failure with just plain old soil from the ground?
