Way too much value put on slurry anyway.
Cut Sward 3 to 3.5 bags per acre should meet minimum requirement for P&K.
Composition of cut sward please.....
It is getting 1.5 bags /acre of 18-6-12 when it dries up.
Hi,
For ground that's getting no slurry, what fertiliser should I be putting out? and how much of it for good first cut silage.
P&K are both at index 2, and 2t of lime has been spread per acre.
24-2.5-10composition of cut sward please.....
Remember though we express P and K differently over here.

A lot depends on your clover content too.
We have one field here that apart from some dung has not received any fertiliser for the past 2 years.
It is getting 1.5 bags /acre of 18-6-12 when it dries up.
why?how?

Would have little if any effect 18-6-12 will grow huge bulk in a crop expensive fertilizer though.how would the reduction in nitrogen versus the cut sward effect it I wonder.
Haven't priced or used 18-6-12 in years since the nitrates came into force all my soils above index 3 apparently.Tis no more expensive than the 4 bags of cut sward we have been using.
Digging this up again a year later......
So for the last 4 years we've taken two cuts of silage each year with a single grazing of the aftergrass.
The ground has gotten one spread of slurry in that time and 7 bags of cut sward each year.
I've been curious about our fertiliser strategy for a few years now, some lads would say the cut sward isnt enough, some would say that so much of it is too much.
So we took soil samples in autumn 2010 and again a few weeks ago, sampled four plots using the same map each time.
Average pH has increase from 5.6 to 6.2
Average phosphorous has increased from 4.9 to 9.7 mg/l (from 2 to 4)
Average potassium has decreased from 97.6 to 92.5 mg/l (from 2 to 2)
So we're flying on P but loosing out on K
how much N is in your fert?

Looking at various permutations to get a bit more K out for the second cut fertiliser and if I was to spread some nitrogen seperately to P&K I'm wondering about urea versus CAN. I have some notion in my head that urea can only be used in spring? or did I dream it?
No slurry or lime at play.
