Liming grassland

Agrian Brian

Hi all,

I have 8 acres of grassland to lime, the soil test says it requires 5 tonne per acre.
Is there a danger in spreading that much in one spreading? Heard something about not going above 2.5 tonne lime per acre in one spreading????

Cheers.

Two tonne max. For the next three years. You'll be close to having it sorted at that stage. You will have a good response fairly quickly.

As in 2 ton per year?
Would that not leave the ground very tender?

What sort of ground is it OP? If it's cutaway bog and too much lime goes out in one go it will turn to jelly.

Teagasc say it is ok to put out a max of 3 tonne/ acre.

I really don't know. Not an issue for us.

Unless you are in a high molydium area you can fire ahead with 2.5/3 ton

We are in a high molybdenum area. What is the problem with higher applications and molybdenum? We'd usually apply 2tonnes/acre.

Excess molybdenum can induce a copper deficiency in cattle...

Signs and symptoms of copper deficiency include: change in hair coat color, diarrhea, decreased weight gain, unthrifty appearance, anemia, fractures, lameness, and decreased disease resistance...

Can be offset by including copper in the diet.....

I think I remember something about the Mo binding with the Cu and making it unavailable, that it can't be absorbed.
But it's a long time since I left school :-)

I know that bit. What's the problems with lime and high molybdenum?

Mo becomes more available at high ph's

ph affects the reaction between copper and mo.

6.2 of a pH seems to be the cut off point for pH in a high Mo area. Above 6.2, Mo is increasingly more available and causing increasing problems with Copper availability.

all depends on land type imo

if you have soft enough land then i'd cut it back to 1.5 tn per acre

good free draining land will take the 2.5-3 tn ok

Just saw on FJ app, that now is the ideal time to spread lime.
We've sheep on the meadows & they could do with lime, if we were to spread now, would the sheep still be able to graze & would it affect sowing for the first cut in spring?

Spread a few weeks ago and had sheep on it a few days later? No issues.
ThrE longer u leave them on it the longer it will take to come back but you need it cleaned off if it's to grow clean grass next year

Going to give them another 2 weeks then whatever is left they can graze with their lambs in spring.
Main concern I have is there sufficient time if spread now, that there won't be an effect with 18.6.12 & urea in the spring & the Silage in June
