Granulated lime versus ground limestone

[Ashtree]

No worries, it all probably sounds like I'm ranting, but it's just a case of repeating!

Your silage will be fine. Unless you had a particularly dusty load of granules delivered, like a new customer of mine who said when he was spreading it that " The aliens could of seen me from outer f***ing space!!"

Actually spread some last spring and tractor was covered in white dust afterwards. Spinner spreader also getting blocked at the outlets. A very frustrating experience.

This year much bigger and free flowing granules. No dust to speak of either.

NV tends to be 45-50% on chalk. Chalk is a soft material so tends to get to work quickly if fine enough and has a good reactivity.
Wouldn't last as long as what though @Henarar ?

Ground limestone

Ok, I defer to you undoubted knowledge.
In fact in my case I applied 75kg of calcifert to silage griound for first cut, on an old ley.
Applied two weeks ago, and probably harvesting last few days of May!

Wasn't sold by any salesman, just ph lowish at 5.7 and wanted to give it a boost thinking (incorrectly it seems) that I would get a quick change for the better in soil ph.

Bit worried now, about preservation

75 kg's a Ha ?? i would say next door to no lift ... doing some tests here on ground put on 250 and 400 kg's per Ha last year will report back once tests are back

I missed this first time round. Where did you get the rate of 75kg/ha? That must be a mistake, I'm afraid. 75 kg of lime dust per hectare won't budge things one tiny bit.

Not having a go, just wondering.

 

[Chae1]

Been told you need 125kg/ha of calciprill per year just for maintenance. We put on 250kg/ha. Every second year on short term cropping let's.

A useful fact sheet that I posted a while back, it doesn't get into an argument of which works most quickly but it does tell you how much lime you need

ps Pete is right.

Interesting document, all I would add is that this is from America and their ground limestone will have a different spec to what is available in the UK. Also, there is no mention of NV on that table which will have a significant bearing on application rates, i.e an NV of 25% will not be as effective as an NV of 50% with similar particle size.

 

[ford4000]

All very complicated. .so I've just put 150 tons of Mg lime down

 

[Yale]

97 tonnes here.

I indeed bow to your superior knowledge, this was only posted to be factual. NV and micron size change how it works and this is down to you lime experts.

Only to point out that if you need lime this is a guide to quantity, how and when is over to the experts.

Did you find it hard to get a few days without too much wind too

Did you find it hard to get a few days without too much wind too

Did it on Monday so it was quite calm luckily.

intresting for me to go from 5.5-6.5 it would take 10 ton's per Ha or 4 ton per acre .. rule of thumb being .1 of a Ph per ton applyed based on nz limes and soils

 

[Mounty]

@ford4000 We get quite a bit of down time with the wind. Can see you've had to pick your time for 1 job, you can imagine how much fun that is with multiple jobs on a daily basis.

I took this vid last week. Thought a few reading this topic may be interested to see one thing that can contribute to a reduction in pH levels. If you're colour blind, might not be so interesting.

Is burned lime worth the extra over normal calcium lime?

 

[Mounty]

Not sure who on here has access to it these days but we don't touch it. Not easy to spread on the stillest of days.

 

[Derrick Hughes]

Is burned lime worth the extra over normal calcium lime?

£100 ton down here so no , but its fantastic stuff, I spread tones and tons if it with no cab on

 

[Jgs]

£100 ton down here so no , but its fantastic stuff

£55 versus £21 spread and delivered not sure if it is worth the extra?

 

[Mounty]

Well theoretically you only need to apply half the tonnage with burnt lime vs standard calcium lime so won't be far out. We put it onto Pak Choi in glass houses where there is sometimes a pH of 4.5 and needs a very quick fix due to short growing time.

Just don't get it in your eyes, mouth, nose or on sweaty palms!!
