    I'm not sure your article is relevant to this discussion. No one here is talking about spring applications. We're all talking about fall applications. You said in your first post that fall applications should be timed such the N is used and depleted before winter. The article you linked suggests that fall applications should be made late enough that the N is NOT depleted before winter and carries over until spring, so that the nutrients are present without needing a spring application.

    You just linked to an article that said what I already said and what most of the posters here are already doing.

    I tried fertilizer treatments in my back yard, early October mid Oct, and mid-November of 2011. I saw no difference in spring of 2012.

    If we used your 'take' on the meaning of the article, then :

    What is the difference between,,, Fall/Winter application still on the soil,,, in it's prilled form, ready for release at the first warm rain,,, what is the difference between that and dumping early Spring NPK onto the turf as soon as the snow melts ready to release at the first warm rain...?

    Again,,,
    If that is the meaning of the article then there was no point for the researchers to even differentiate between Fall and Winter ...

    It is necessary to read and think about what the author is presenting... it is necessary to study and analyse the points and counterpoints brought up in the articles we read to see whether it is clearly understood...

    It is a mistake to look at this article as a support for the status quo...

    That is why I stated earlier that this could be a great discussion if thoughtfully engaged... Will misunderstandings, mis-interpretations and hyperbole prevail??? :)

    Perhaps this one statement,,, copied from the article,,, as the first sentence of a paragraph,,, should have a thread of its own...

    " The true advantage that late-season fertilization provides to turfgrass root growth is realized during the following spring. ...

    but for now,,, let's contrast with another statement from the same article:

    " The rapid decline occurs because carbohydrates are needed to support the increased shoot growth resulting from nitrogen applications made early in the season ..."

    I didn't read the article, so I'm left wondering what they are referring to in the second sentence you quoted. The rapid decline of what?

    The rapid decline of carbohydrates... the full paragraph is a few posts up... :)

    The article is essentially saying that the early app of NPK stimulates the shoot growth to an unhealthy extent that burns up energy reserves in the plant... also indicates that this occurs at the expense of the root development that is the normal healthy activity of the plant,,, at this time of the year...

    So in a nutshell,,, the Early Spring app of fert and pre-m results in a double-whammy,,, that only hurts the chances of a strong root system...
    Wait a couple of mowings and it works out fine... :)

    I'm planning to put some Milorganite on my yard this week.

    Here is a comment from the: http://www.coopext.colostate.edu/4dmg/Lawns/mythwint.htm , that disagrees with you on that...

    "... If you have very sandy soil (uncommon in the metro area except along South Platte and eastern areas) do not fertilize later than late September, as nitrogen leaches readily through sandy soil, especially during winter months, and will contaminate ground water. On sandy soils, it's best to use "slow-release" nitrogen fertilizers such as organics, IBDU, or sulfur-coated urea, to reduce potential for groundwater contamination..."(emphasis mine)

    Haven't heard back from any of my questions... you were telling me what was common sense practices and I was looking forward to a real discussion... is that off now???
