    That is a very good question. I'm hoping that you will answer that. From reading your posts and seeing your credentials, I am assuming you are one of the most qualified to explain.
    Here in Missouri we have a lot of clay. During most landscaping jobs I will add topsoil to the new beds. Some customers prefer the pulverized top soil which cost almost twice as much.

    in soil science and you're asking US ?:eek:

    The blackest dirt around here is muck with very little fertility. Sure looks nice though.
    I would say nice tilth and a decent amount of OM. Not the fluffy light stuff used in flower beds.

    (is this a test?)

    A good topsoil? for what? turf, shrubs, perrenials, I would say a sandy loam for all the above, but sometimes and often you must work with the existing soil and amend to improve fert. and drainage

    It's the "top" layer, if you will, of earth. Usually it consists of dead and decomposed plant and animal matter.

    How'd I do, Teach!?

    Top soil is as last stated the top layer. Also called loam. Screened is a better choice to get, as it creates less work because rocks, stones, and sticks are removed in the screening process. Normal application is 2"- 3". Another option is farm loam. This loam is usually very full of nutrients due to fertilizers and "natural" fertilizers from farm animals. Anything that grows from seed such as grass seed will due much better in loan/top soil than it will in natural soil like clay or sand. Hope this helps.
  10. Be careful applying soil over existing soil,if it is different! 2-3 inches creates a layer, then water doen't move thru easily!

    Incorporate the two soils! roto till
