Ok I GOTTA BE HONEST. I am licensed have been for 3 years now and really dont do muvh fertilizing until this year I'm getting a bit more agressive with Fert apps. I also have to be honest my record keeping hasn't been the best and was wondering what all is required or if anybody has the direct web site with the Iowa Dept of ag and land stewardship templet or their templet for records???? any help or adice would be awesome. I pretty much have just been keeping track of temp wend time what applied at what rate and how much. I also leave the signs in the lawn that a pesticide has been applied and to stay off for 24 hrs.
