    We've always gone fert-only for silage cuts but with the derogation splash-plate ban coming in by mid-April we'll have to mix both next year.

    I've seen arguments for slurry the week before urea and vice versa.

    Min of a week apart if a little rain and I don’t think it matters.

    Does'nt matter as long as you leave at least a week between them, especially UREA based products.

    Is it too late for lime. If we got a dry spell?

    Lime is a 365 day of the year job only dependent on ground conditions.

    It's rock dust it ain't going to disappear.

    If frost was a problem with limestone, Kilkenny would be underwater by now.

    If frost did fracture it even more all well and good but it's ground up so fine anyways by machine that it'd be negligible benefit from frost. And any rainfall won't matter either as it'll wash it into the soil profile.

    The only thing frost matters with is nitrogen and that's basically because it'd be so cold that plant nor microbe wouldn't be active to take it up and it'd either leach or evaporate.

    3 months if using urea, can based products not an issue. Have heard differing opinions on protected urea, some say no issue others say 3 months. Also recommended to leave 3 months after for slurry
