Which is best, lime dust or lime granules

unfortunately not delivered, all ex works, but that’s basically the choice, there’s over 100miles of haulage to add on that!
I'm hauling mine 150 miles . Its better lime and delivered price is less that that collected price . I'm sure you could haul lime out of Buxton and get it cheaper than that

Worth mentioning too that the ‘flour’ is a milled and dried product, so you wouldn’t be paying to haul water, it’s not normally sold for liming but rather goes off for further processing, some of it ends up in some of the Origin fertilisers I think I was told once.
 
I’m no expert at all, but if you’re going to lug anything that far you might as well bring the best quality you can. Haulage can often make it break the cost and, as I said earlier, if you’re right on the doorstep of a coarse but very cheap source of lime then it can make economic sense to use it.
With both at an NV of 52% it’s just a case of choosing the sample with the most fines in it, which is easy to see.
Maybe the granulated lime could work for you if it’s got to come so far. That will depend on your starting pH, what you want to get to and what you want to grow.

I have recently sampled ag lime at 32 locations around Ireland for the quality assurance trademark known as Grolime. There is a very high compliance rate with all sources generally achieving a TNV of above 95%. The grading can prove troublesome for some at times, particularly the 150 micron sieve limit but failures are generally marginal. The problem is usually the wear on hammer mills. One quarry operator was informing me that when a new set of hammers are inserted he can expect about 50% max passing the 150 micron sieve for about a weeks production. This then drops by about 5% every week of production so that gives him about a month of compliance operating flat out before hammers in the mill would have to be turned or changed. I think only for the assurance scheme which requires bi-annual independent sampling and testing, a lot of folk may neglect to keep on top of hammer mill maintenance and therefore lime grading would be questionable

It’s for permanent grassland, needing 2-3t/ac, would like to hit 6.3 one day, it’ll mostly be 5.4-5.8.

You’d think the cost of haulage would have come down a bit with the diesel price drop, maybe it’s worth looking further afield.

Maybe we could make a list of suppliers/prices/quality?

It's the tax that is the killer , ag limestone is worthless except to farmers .

5.4 up to 6.3 should be quite easily achievable with 2t/ac of good quality ground lime

We use Parkmore lime. It works. Must be one of the 2 that can be trusted!


I was speaking to one of my friends who drives a lorry hauling aggregate for breedon. He said parkmore were into lime with a higher NV and thought they could charge more. How many farmers would buy lower nv lime for a few £ less? Most I suspect. Another one is how many adjust the application rate, taking into account higher NV?

Yeah I had 100t Parkmore lime a couple of years ago and it went out at just under 1.5t/ac, it made a noticeable difference, the idea was to do the same again the year after but it hasn’t happened yet. Had a load of the coarse stuff out of torlundy, same colour but noticeably more grit in it as expected. Would really like to know if the flour would be worth the extra expense tho, I suppose you’d need to have them lab analysed to really know.

I’ve been told that the coarser stuff would ‘last longer’, but I’m not convinced, I’m assuming the limestone is quite hard, and anything over 1mm is basically inert, I’d love to take a couple of loads of the flour but I’d be looking at £50/t+, it’s a lot of money, but then maybe 1t/ac would do more good than 3t of the coarse stuff!?

I’ve been thinking, and it’s getting late so may be nonsense, but if you class sub 0.150mm as the active part:

Torlundy coarse is £13/213kg of fines, so £61/t of fines.

Parkmore is £19/360kg of fines, so £52.70/t of active stuff.

This makes it look likes no brainer. I wish the torlundy flour had a 0.150mm %, it would be interesting then.

My thinking is totally unscientific. But very fine lime works quick but you have to spread more often as it disappears quicker. Leeches out I expect . So if you dont want to spread to often a slightly course lime works better. This is where it gets interesting. As I think some limes work better that others of the same coursnes, having said that I would not buy screened lime
