P & K while grazing?

restive

Is there any harm in applying P & K to land that is currently been grazed by beef animals?

No work away, if cows with calves at foot keep a bucket with them tho neighbour lost a cow to tetany after they kicked the bucket out of reach. He has pigs tho so would be higher risk with their slurry I guess

Something like 18-6-12 or pasture sward would be ideal. As above keep mineral licks out with them at this time of year. Grass growth is good but the mineral content in the grass now would be low

I cannot see that it is right having animals eat fertiliser.

I know that plenty of people do graze land where fertiliser was recently sown but for me it is a no.no.

They don't eat fert. If I don't spread it every month I run out of grass simple as. From now on I try as much as possible to follow the cows alright but there may be cases where it's blanket spread.

What would you be spreading & how much /Ac

Have a bag of urea and either 2bags of 18.6.12 or 35units of can+s, depending on whether ground got slurry, out on the grazing block will follow a bag of can+s every round for the next 2 or 3 and then go with regular can or urea. Sulphur helps the plant convert the N to more usable protein in the grass advice is to get it out before may. Overall last year I spread 238kg/ha of N

That's a nice bit
Would it be dangerous to spread 18.6.12+S & CAN+S

No I'd say, Well the advice is to get 15 units of sulphur out on grazing ground and 20 on silage ground so if you spread it over a number of rounds on the grazing ground i.e. A bag of of one this week and spread again in 3 weeks or a months time depending on stocking rate.etc. Some say too much sulphur at the one time such as ASN, which is 20 units of sulphur in a bag I think,on grazing ground may effect fertility but some do it and have seen no effects but little and often is prob better for grazing ground from now on when you'd be moving around the farm faster. Silage ground makes no odds how it's spread once the N is gone out of it before cutting

Not recommended to use high levels of S where Mo is high and/or where Cu is low. S locks up Cu.

So is no S better than too much?

Depends if you have fertility problems in cows or not. 5 units would be better than none if the soil needs it. I've heard that land that has been in tillage for a long time needs it in low S areas. I think we used to get it free before ESB put scrubbers on the smokestacks in Moneypoint.:D

Thanks, fertility isn't really a problem now that We're using aids.
My understanding of Fertilizer application is poor (why I'm asking all the stupid questions).

No such thing as a stupid question as they say, plenty times I've felt a bigger fool for not asking. Have you soil tested recently?prob the best place to start. No point if slurry and fert already out,Jan before spreading is the best time. With regard to sulphur if you've had no issues def spread on the silage ground anyway, would help the final p content of your silage

Your thinking is wrong there unless you live well into mainland Europe. The smoke from the stacks in Moneypoint travel for several hundred miles before coming down.

What about rain?

Sorry that is with the rain otherwise it stays in the atmosphere indefinitely.

What about during inversion conditions?

Are you asking about inversion layers? The height of the stacks over comes this,
but I don't think you are asking this, your just trying to sound clever.:D

What goes up must come down.

(Unless we're talking Helium which goes up and out into space).
Even satellites orbiting the planet are slowly descending to earth.

We spread sulphur now as fertiliser because it's not being deposited like it used to be when factories and homes were burning smokey coal incessantly.
Remember our good friend "Acid Rain" from the 80's.
That was the result of burning smokey coal and lead and other emissions from combustion engines.



Acid rain still happens but not on as wide a scale in this part of the world as before.
You're right about it being blown into Europe (depends on wind direction) but it was also washed to the ground in this country here from factories and houses.

Sound clever or not Inversion layers can form at any height.
Keep an eye on the Valentia Observatory Tephigram if you don't believe me.:)
