As stated in a previous posting, begining January 1, 2012, Michigan law restricts phosphorus fertilizer applications on lawns. Our friends at SOCWA, the Southeastern Oakland County Water Authority, has compiled a list of Earth-Friendly Fertilizers for Water Quality Protection.
Lillian Dean, SOCWA, has sent out an email to Composters and this information may be of interest also.
There are some are new fertilizer products for 2012. Ace Hardware and Aco Hardware stores are carrying the products. Please be aware that two of the most popular products, thought to be phosphorus safe are not, they are Milorganite and Ringer Lawn Restore.
As Dean states in the email, if you look carefully, Scott's does not seem to have ANY PRODUCTS FOR SALE that meets the fertilizer requirements, either. Some even have more than the required amounts of Nitrogen, another product under scrutiny. They may even have unwanted herbicides and pesticidies also. So please read labels, or if you have a company fertlilizing your lawns, request they inform you what is in their products that they are using.
Please read the previous blog and refer to the Fertilizer Act drafted by the Michigan Department of Agriculture and review the application rate. (0.25 pounds of phosphorus per 1000 square feet.)
