Dead earthworms on surface

Did you spread slurry there recently?

Ya, slurry seems to kill them. A few people have posted about this in the past. Not good for the soil in the long run.

Apparently not true.

have seen it in past. heavy rain plus slurry seems to kill them. Could it be a lack of oxygen?

Ivomectin in the slurry also kills the bugs and insects in the soil

It's oxygen and probably some burn or poison element.

I've only seen the worms come to the surface lately with slurry spreading. I never had it before. It was dairy washings. But there's teat spray residue which is new in the mix, and I'm mixing in humic,fulvic acid too. They do not seem to like this. It's probably a bit strong mixed in. But..

What I'm doing is seemingly breaking the ground up and allowing more soakage. So I'll keep at it. I spread it on the beetle ground and they are still burying away anyway.

Humic acid is more for soil.

Fulvic acid is a finer more processed version of humic acid used really through the leaf.

If you leave dung or compost or anything to rot it'll ooze humic acid. How it works in soil is it breaks down stone, clay, grit into humus soil. It'll release the minerals and make them biologically available that's to life and plants.

There's a carbon element in it too so it'll bind up any free nitrates in the slurry and hold them that bit longer in soil. It should buffer any chemicals that may happen to be there too and break them down faster.

It's made from brown coal. Bit of an issue there being a fossil fuel but it's very small quantities used and it's covering a very large area and being applied is aiding more carbon being sequestered from it being applied as well as the N retention and chem buffering.

The product just happened to be humic and fulvic together and it's really made for foliar but I'm just using what I have with the washings too.

Imported from China direct from the manufacturer.

I'm not sure if this particular product is available in Ireland?

There are other sources of product in Ireland though and then there's the option of seaweed,molasses maybe through slurry if you wanted.

A bag of seaweed meal will do very little in the tank plus you have to buy it.

You'd be better if you wanted to buy to buy cold pressed liquid seaweed. But if it's for the slurry tank then collect it yourself. And either in the tank straight or if you want to drag out and extend the benefit over a longer period. Put the seaweed into an ibc with molasses and let the liquid into the tank every so often or whenever and top up again with water and molasses and repeat and repeat.

Any amount of molasses in an ibc. But 20 litres in a 1000 litre ibc of seaweed would draw out the minerals and make it more chelated bio available.
