Well I mean we all have seen generic schedules for fertilizing - some people are even fine with just going by some basic rule of thumb like 50 pounds of 10-10-10 per 10,000 sq ft per 6 weeks. I have a lawn that is being taken over (intentionally) by Palisades Zoysia. I'm looking for a more effective program - cost isn't as much as an issue as is just wanting good healthy results. I don't insist on having a neon green lawn, either, at the expense of hurting my grass in the long run. As an added bonus I have the ability to apply small amounts of liquid fertilizer through fertigation, to my turf, or can apply dry fertlizer, or both. I've had every rec in the book thrown at me. The last one was something like a low nitrogen (8% or so), low phosphates (8% or so), high potasium (25% or so) with iron. I was told this would be kinda costly but product a very nice looking and very healthy lawn without giving the lawn too much nitrogen and causing it to grow too quickly in the summer heat and/or possibly burn it and that I could apply this 8 times a year during the growing season. But still... I'm at a loss. I get different advice everywhere I look. Short of constantly submitting soil samples for testing - how can I formulate an effective schedule for my turf?
