Cheapest way to test soil pH using red cabbage
My B.S. is in computer science, minor in chemistry. I wrote this procedure for the English Roses Forum ... benefited mostly international folks. What Kimmsr wrote is right about pine needles are neutral, and the NET result of decomposing leaves is alkaline. Google "University of Illinois and Organic Mulch", and you'll see.
I still recommend getting your soil tested by University Extension, local county, or Earthco. first, but if you need many samples tested afterwards, my $1.50 cent procedure will save you money and time.
See the link below for the procedure I wrote to get fast soil pH using 50 cents red cabbage and $1 bottle of distilled water.
