    Had a.phone.glitch....

    Seems like most.if.not.all.the.bigger fert application companies in my area want customers.lawns.to.grow a.foot.each.week in.the.spring.and.summer.

    I.have.been.using.slow.release.synthetic fert.and.organic.base.products and my.customers.are.happy.with.it. Milorganite has not proven to me to be a.cost.effective.product when.compared.to.dried.poultry waste based.fert.with some.synthetic Nitrogren.added.

    This area is also loaded with forget about the lawn.in.the.Fall....we will hit.it.in.the.Spring.

    So.in.light of.proper Fall.applications 60%+ of the entire.seasons fert goes down for cool season grass....what works best?

    An analysis with no phosphorus and about 30 percent slow-release nitrogen (and the rest fast-release nitrogen), and about one-fifth as much potash as nitrogen would suit me fine. However, since you prefer to include organic sources--you will end up with some phosphorus.
    Too much fast release may not be absorbed by the roots and will leach down into the ground water. A slower, more steady feeding, should be mostly absorbed during fall and early winter.

    I got some some urea that is only about 16% slow release while the rest is available more quickly... as long as most of it is used up before the grass stops using fertilizer, is the main thing...

    however the question is: "When", does the lawn stop using fertilizer???

    We know that very little N is being used when the ground is cold, but how cold is cold??? :)
