    Just a bump for this. Would ye reckon it OK to spread compound fert so after lime.

    Slurry is not a runner I know and Urea because of the ammoincal nitrogen being lost but doesnt CAN and compound fert also contain some ammonical N.

    In cropping lime is regularly applied to the ploughing and compounds applied pre drilling

    Came across this last night. It says 3tonne/acre is ok on land requiring a lot, like ours.

    Interested in the previous attachment pat. Have very high PH around 7-7.3 and from that info it is unsuited to Urea. Always spread Urea for silage rather than CAN for cost effectiveness. Is idea unsuitable for high PH land or is that only with lime application?

    Don't see the mention of Urea. I think it's just lime you don't spread at that pH

    JDI,

    I'm referring to the attachment pat posted 7 months ago where is says not to spread urea for 3 - 6 months after lime. The rationale given is that Ammonia losses from urea are greater the higher the PH. Even though lime has never been spread on the land there's a high ph.

    I get you. I was thinking with such high pH you just wouldn't be spreading it in the first place. Only time I could see it being justified for that soil is gran lime at reseeding and that disappears quickly enough. It is mentioned on the second attachment that 7.2 is the upper limit for full utilisation of chemical fertiliser. Looks like you're blessed with your soil.
