    Finally saw good snow here the other day, about 6"-8" at the house. Unfortunately, our snow pack that leads to the run off areas and storage facilities are no where close to here. Another round expected to drop 4"-8" at my house tonight, but a lot less in the city. Doesn't help our overall water shortage much, but helps with covering lawns, and preventing winter kill. As well as helping keep the fire danger down. Living in the forest amongst lodgepole pines is pretty scary lately with how dry its been.

    There is no need to cycle and soak as long as your precipitation rate doesn't exceed the infiltration rate of the soil.

    How does elevation play into this?

    I don't think elevation does, but slope might :)

    It doesn't ..... nor does slope really. If all water applied infiltrates immediately then slope is not a factor. That said, as you approach steady state infiltration, your potential for runoff will increase, particularly with increasing slope, which is the reason you see a "slope" setting on smart controllers.

    Good information. I've got a customer who has some sorta PhD in soil hydrology or something or other that I've meant to discuss how water moves through soil...whic ing moisture for uniform du when using drip for grass...how much organic matter can change this etc....can water move upwards so the drip can be installed lower so aeration can be performed.slope can matter if du is poor,no?
    you lucky trip guys will get some slope and speed exercises

    It is not uncommon to need to use soak and cycle on our clay soils.

    The problem with that is first getting the water TO the soil. With thick thatch and layers of built of crap, sometimes the water will run off on slopes before it can even get to the soil. Yes, the customer should do proper aeration and other processes to prevent this, but it doesn't always happen.

    What is the 'crust' called which developers on top of the soil after it dries out? Until water saturate s this crust it runs off ...
