Hello Johnathan-

I'm sorry I don't know of any in Colorado, but perhaps some of the info below will be helpful. I'm a member of the BrixTalk yahoo group which is VERY soft rock phosphate oriented, and through them I've gotten some of this info. I've been trying to put together a comprehensive list of sellers of SRP for a while, but its been sort of difficult.

MINNESOTA
http://www.aglabs.com/
Jon, or whomever you speak with at International Ag Labs (IAL) should be helpful to speak with. IAL sells either Calphos or the Idaho SRP in 50 lb. bags for $15 per bag. They also sell Idaho SRP in large tote bags for $300 per ton and they quote semi-loads delivered for $200-325 per ton depending on the location and which source they pull from.

WASHINGTON
http://www.tandjenterprises.com/tandj_contact.htm
Thomas Giannou of T&J Enterprises out of Washington is on BrixTalk. He knows a lot about growing high-nutrient foods. Here is a quote from his comments when we were assembling the list of SRP carriers:

"The calphos I sell is pelletized. It is actually a powdered form that has been prilled with bentonite (a type of zeolite clay.)
As soon as it gets wet, it breaks down to the powder form. Prilled or pelletized products are sure a lot better than trying to
spread a fine powder through a spreader. The lime and SRP are prilled using bentonite and the Gypsum and Planters II
are prilled using molasses. I can furnish these products in truckload sizes, pallets, 50lb bags, and any size under 50lb bags."

CALIFORNIA
http://www.harmonyfarm.com/
California supplier that supposedly carries SRP, but doesn't list it on their site so I guess you'd have to call them. They do ship.


A source said Fertrell dealers did not have SRP. However, they carry something called 'Frostrell' ?? (not sure about the spelling, or name) and that it is as good as SRP. (That would be up to you to determine.)

Finally, if you can buy by the semi-load, you can try www.fertilizerbrokerage.com and find out if they can source it closer to you.

If you find a closer source for you, I'd appreciate hearing about it.

Jody

Would anyone have any leads to Colorado (Denver) local sources of
colloidal soft rock phosphate?

We are using it in a broad acre fertility program this year.
The only source I have been able to find is through Ohio Earth Foods at
