Rock dust saves the planet

[mo!]

Spreading rock dust on fields could remove vast amounts of CO2 from air

It may be best near-term way to remove CO2, say scientists, but cutting fossil fuel use remains critical

i will let them come spread it for free if they like, put my name down,doing my bit for the planet and all

Wow, so adding ground limestone to fields could reduce the acidity of soils improving crop production, no doubt farmers will be well excited about this fantastic discovery.
And this dust from the steelworks sounds exciting stuff too, wonder what they’ve been doing with it up to now.

Need any grass seed with that?

Finally,some news which could genuinely help farmers and also help Lock up emissions.

This does not mean that the problem of energy consumption and emissions should not be tackled at source.

Processing and getting ‘rock’ on farm is also destructive and creates emissions so it should be treated as a sticking plaster.

As is the case with all these stories, there was precious little in the article to actually go on. No mention of what types of rock for a start, just rock ffs. And presumably the pixies are grinding the rock down in the first place?

A member on here sells volcanic rock dust. Was at groundswell. Think @martian tried a load.

How much to send a wagon to Mars for some Martian rock dust ?
Sharp intake of breath.......can't do it till next Tuesday, and even then it'll have to be a backload.....

its basalt,

Crush the right rock and spread it on farms to help soil and the climate

Researchers run the numbers on what could be a win-win.

im not sure what if any the neutralizing value of it is. limestone releases co2 when it reacts with acid in the soil, so that isnt helpful on the climate change front.

Thanks for the link. Much more informative than anything that's ever been published in the Gruniad.

I think you need to read it again.

What we really need are books like Slags of the World so we can choose the best slag for the matter at hand .

I think @Kevtherev had a few copies, but maybe that's untrue

that book sounds more like @Bald Rick territory to me.

All out of slag catalogues but hoping to print a slag calendar for next year.

Ah. The page wouldn't load for me so I had to do to reader view which obv didn't show much of the article at all. I've tried it on a different device now with more success

I’m sure @Kevtherev has mentioned finding such catalogues in lay-bys whilst trimming hedges allthough iirc he has said they’re not as common as they used to be.

This is Kev and Petes new venture, they have been working on it for months. Kev writes stories for the papers under an assumed name and Pete is busily gearing up for a whole new tranche of spreading.
In a couple of weeks there will be another article on how these new miracle holes can accomodate all the surplus CO2 and just geuss who, has a load at the back of his shed he never sold

I wondered who was behind the "Clean Coal" and "Carbon Capture and Storage" initiatives - I should have twigged!

I've just googled slags of the world and it didn't come up with what I was expecting at all.

Glad to hear you’re taking this important discovery seriously and reading up on the subject, I’m sure you will find lots of interesting information that you didn’t expect to.
