Phosphorous in soil

  1. Dec 22, 2007 #1
    Hi, I was wanting to test garden soil for its phosphorous content. I've seen test kits and electric/chemical kits and the like, but is it possible to do this DIY? I'd need to create a solution and have a scale to determine results. Thanks for your help.
