Been recommended this today by someone who knows his stuff

Have always discounted granulated lime as it looks expensive but looking at the application charts it seems you need a lot less to get the same effect due to availability

I like the idea of being in control of lime applications ourselves, logistically lime on stubbles is a nightmare, trucks tipping in field gateways that then need cultivation to sort and getting contractors here in good time in small windows like between wheat and osr plus narrow spread widths meaning lots of wheelings - this year it was just not possible with the wet conditions and fast turn around of ground, osr drill following the combine out of fields etc !

This stuff can be done by us up the tramlines giving us a much bigger window to apply - much better if its is any good and cost effective

Anyone used it ? What on you reckon ? I know it's not popular on BFF when mentioned but let's face it lime contractors are never going to recommend a product you no longer need their services for are they.

Used some last year and works well. Used the various rate maps to spot apply, but we had a corner of a field that dropped to ph4.5 and hadn't grown anything for a couple of years. This year it has established and grown, so it has certainly worked for us and be in control of when it is applied.

Kinsey seminar will be very useful for this type of decision. He'll say that the decision to lime should not just be basd upon pH. pH is after all the concentration of H+ ions and not Ca2+ ions - for that you need pCa. If you're thinking of spending a good deal of money and can hold off on the order until after the seminar I would.

What type and depth of soil tests have you done on the fields you intend to fertilise? Why are you wanting to apply this product? If it is just to comabt soil acidity then I would definitely wait until after the seminar. Also if this is your goal then I'm curious to know why you concluded that MAP is right for you. If your soils are acidic the acidifying effect of MAP is not useful. On our farm we have water pHs of 8 and so MAP is useful.

All fun stuff.

Not considering it for ph reasons really more wanting to feed Ca to the plant

This is why I think it might be a better product than ground lime as its more available

Only soil testing top 3" - 4" as that's where we are growing the crops, the way I see it is soil below that depth is just the water store

Think I will hold off any spending however until I have heard what Kinsey has to say !

Have a feeling it might change my ideas and views on many of these things !

My land needs a bit of gypsum, half a ton an acre, just to free up the surface where the drill works. I spoke to the guy at Lamma about Calcifert S, twice as much Calcium and two and a half times as much SO3 compared to plasterboard waste. Also all available straight away, rather than over years, like gypsum.

Self spreading any time of year must be better.

But 180/ton. I'm waiting for quote for plasterboard delivered in, So will wait to see how they compare.

Kinsey will enlighten you all. Had a day with him15 years ago, Albrecht tests ever since, got the biology working, no P or K or lime. Before,we used to lime every few years, but it doesn't' acidify any more. pHs always 7.

Simon - where are you located ? It no use to me on our soils but I have an almost free source of plasterboard waste if your interested ? If your far away haulage kills it though
