What was on the ground before you reclaimed it?

The trace element analysis looks ok, but why no molybdenum analysis?

The results that are very high in manganese - why would this be?

When we were reclaiming, we found a place where the stones were as black as coal, and the earth all round the same... they almost had a burnt type appearance... I thought it odd at the time, but no one knew why they were like this..

I forgot til I just happened to spot the high manganese there now - but maybe the two have nothing to do with each other

What was growing there you mean?

A lovely crop of briars and ferns... one to be proud of plus some blackthorn mixed in to make it more hateful...

Why no molybdenum - I have no idea to be honest Ganmo.

Molybdenum locks up copper, so if mo is high you need copper to be way higher.

at similar price it wouldn't be value, just a thought.
P is supposed to be running out, getting scarce, probably why the 6 units of P is as dear as the N and K in 10 10 20

No, all thoughts gratefully received...

Yeah, P seems to be the dear one all right - acourse like

I just need to by ground lime and a shovel don't I

Green farmer

Unfortunitily yep, Looking at the chart it might suggest how your manganese is still remains high at the low ph level. I'm guessing all you need is lime ok, but I'm only getting it spread for the first time ever here, so I'll let you know what difference it makes.

I am fairly sure we are very low in cobalt, buts it's never been proven as such.

High soil manganese prevents uptake of cobalt by herbage and can thereby cause cobalt deficiency.

Would that mean ewes would be less likely to take grass tetany because of high manganese

grass tetany is lack of magnesium

manganese is a different element

Hope you don't mind me sidetracking thread John, but got the 2T /acre lime spread here. Anyone know how long before I'd see an improvement in grass from a low starting point ? Will it kill of moss in field ?

it'll help but the best thing for the moss is ferrous sulphate. it works in a few days

IME you will see a initial boost from the nitrogen in it and then you'll see a noticeable difference after 6 months and it will max out at 12 months

I started from a very low base here and it took the second spread two years after first to see a real change

Ah gamno, just goggled it. Said was used to lower ph, want to go the other way . 😊

The fields I did here were 5.5 and 5.8 and haven't been done in living memory, so hoping to get a good boost. Going to put in as much p&k's as I can afford to keep it going. Cannt be any worse then pre liming anyway .

just sprinkle it on the moss patches, one bag goes a long way

Threw out some gran lime on that field that was pH 5.2 when tested last year...

It'll get ground lime in a few months - when the evenings are brighter and I have more time to be at it...

But thought the gran lime might help get a bit more grass growing in the short term... we'll see I guess

Grass isn't too bad on it, the little bit of urea earlier helped I think - even if it wasn't utilised efficiently due to low pH and P...
Edit : you can see in the pic, where I didn't go close enough to the headland, and it doesn't have the same growth...

Looking well but not a fan of urea gives u great green grass early but at what cost till the ground?? Always find land that had had urea early never grew like it should rest off year just my opinion.

I'll get back to you

Although that field now is low on everything so will be getting a good dose of fertiliser this year...

Green farmer

I see what you mean by gradient now John, but still a nice clean looking field.

See pic of an organic fertiliser I found - I don't have a price yet, so it could be mad expensive...

But before I ring, I wanted to check something...

Edit : Based on that analysis, the NPK per ton is 40-80-180, or 1-2-4.5 per 50kg (if I am comparing cost to lets say bags of 0-16-0)

Edit :
Given it has apparently 87kg Calcium / ton - any idea how this would improve the pH of soil? Am trying to work out how much lime would be needed along with this to raise pH. How much Calcium is in a ton of ground lime?

http://www.gouldings.ie/our-products/fertiliser/gran-lime/
That page lists granlime is 38% Calcium...

ganmo

It's not the calcium that raises the ph.
It's the carbonate part of the limestone(calcium carbonate) that raises the ph.
