I usually spread slurry after the silage is cut as to have good grass for grazing but this year im going to spread it shortly and spread 18 6 12 a few weeks later to improve silage amounts. A friend of mine told me that there is no need to spread 18 6 12 ,that all i need to spread is slurry and nitrogen. By doing this would reduse costs as nitrogen is cheaper but what are yer opinions on this ?

What about forgetting about the 18-6-12 and put out some potash instead, something like 0-7-30. I see alot of fellas putting out way too much nitrogen. It will work for a few years granted but land will be the worse for wear so best keep all nutrients up to date.

The slurry should supply enought P+K, he needs N to grow the grass, what is more p and K going to do?

There should be nearly enough N in the slurry. But I was told recently that it won't give enough potash. We have put alot of K in the last few years and can really see the effects in great silage yields. Please feel free to corrrect me if I'm wrong:)

even if you inject there is not enough n in slurry.take soil samples if your in doubt about fert requirements

I was speaking to my local co op this morning and was told that spreading slurry and nitrogen would do the trick. Just wondering should i put out slurry first or nitrogen first ?
