| Thank you, Michael, for the link. It's very interesting. Personally I don't like horse manure since it's very alkaline due to the lime stables use to deodorize the stalls, plus the salt in the manure. However, for alkaline soil with pH over 7, neither rock phosphate nor bone meal work. University of Colorado recommends manure for alkaline soil. An acidic source of cow manure, pH of 4, is Green Thumb Organics Inc., LaPorte, IN. The other bagged cow manure I tested Moo-manure from HomeDepo, has pH over 8 for my Chicagoland area. |

| There's a lot of discussion on this in the organic section under the topic "Organic better?" Below is yet another link with quite a bit more on the relationship of phosphorous with plants soil and the environment. |

| I did a double take on the title of this thread. I said "What the heck is soil paper and how does P move through it?" LOL |

| Good links both, thanks for posting them all. Sorry about the title, that's what happens when I write for myself instead of the reader, oops. How about this, Paper on Organic Pee. Maybe, Research Paper on the movement on P in the Soil would have been clear. I'll try to do better, it has been about 25 years since that technical writing class :) |
