Stantec, can you provide any more specifics in your question—what kind of insight you're looking for, and what you see it applying to?

Hi Tristan, In CaGBC CIR #854, the Final Ruling states "provided that no surface-applied fertilizers (greater than 1% phosphorous) are used, fertilizers may be applied around the plant root zone in the soil at the time of planting and not be in violation of the phosphorous management plan for ongoing operational management of phosphorous to meet SSc6.2." My interpretation of this is that if slow-release fertilizer was used at the time of planting it would be exempt from the minimum 1% phosphorous requirement - would you agree with my assumption? Thank you.

Yes, I agree with your reading of this CIR on phosphorous.
