What fertiliser to spread

[Matty6270]

Hi. I just got my meadow field soil sampled and I know I need a lot off lime, and my P is very poor. I need to spread fertiliser this weekend and need help on what to sow. I know it’s not going to be great but I am not sure what to go with.
I’ve attached pc picture below
Thanks

What fert have you got available? Also how soon can you get the lime on?

The lime will have to wait till after silage is cut.
I was thinking of 3 bags of 10-10-20 and 1 bag of pasture swartper acre??

If it’s for silage, you want N on, your lacking in P and you need K for the silage off take so even a simple 17-17-17 would work well If you can get anything similar to 17-17-17 plus with sulphur would be ideal.

I would not be to concerned, I'm guessing that the grass thats growing is quite happy in that environment, not much Ryegrass ?

Putting anything with higher levels of K on will be a waste due to your low levels of P. With fert prices this now I would be concentrating on my N P and S

So what do you think I shud put on ?

When are you looking at silaging? Presumably reasonably soon?

I’d go with straight N if you need to push yield before cutting, then address the issues after. If you put lots of K on now you will get luxury uptake and it will get taken off in the silage (potentially causing issues there).

pH is clearly your biggest problem, and it won’t be particularly productive until you’ve addressed that. It will take a couple of years, and a couple of good lime applications, to catch up. Raising the pH will make the phosphate in the soil much more available too.

So what and how many bag to the acre would u apply

 

[Samcowman]

If there was everything available probably TRupke super phosphate and an NS compound.
Depending on when you want to cut will depend on how much to use. And at short notice just have to use the closest available product you can get.

I plan to cut in 7 weeks

What stage is it at now? Grazed down tight, or a fortnight off mowing?

 

[Matty6270]

It was topped off during the week

I’d get some lime on now then. It won’t be on the leaf to affect silage in 7 weeks time if you’ve just topped it.
Alongside that, I would just put N &S on to boost growth, and accept that the pH will mean half the N is wasted.
After silage is lifted, I’d be in with Fibrophos to replace the K and boost the P (I will be doing just that after silage is baled here, on ground that is low P&K).

Are u talking about 1 bag of granulated lime per acre

 

[Matty6270]

Are u talking about 1 bag of granulated lime per acre

And then maybe 3 bags of 27-2.5-5

No, proper (ground) limestone, at 2t/ac. If you’ve just topped it then it’s an ideal time to get it on the soil, without contaminating the leaf that you will want to cut later.
A bag of prills will do nowt when your pH is near 5. For pasture you ideally need to get it up to, and maintain it, near 6. The level you’re at is beyond tickling with prills.

 

[Cab-over Pete]

All good advice from @neilo

 

[sodbuster]

Fibro phos or p-grow after cutting
