I found these instructions and they seem to make sense.
then I found other "how to make" fertilize websites. The only thing
that I find missing from these fertilizers is iron and sometimes
I remember the month after the huge fires in souther california ( we
had to evacuate). I had the greenest and most lush dark, green grass.
Later I found out that pine needles and ash makes great fertilizer.
That's what was in the air for about a month.
The grass loved it, our lungs didn't.
