Slurry tanker dribble bar

Quantify works better?

So 1000 gallons of dilute dishwasher gives more growth than 1000 gallons of thick nutrient rich slurry?

if your trying to suck thick slurry from a ten foot deep tank, at best your tanker will be 75% full. So put in a few loads of water and it will be 90% full. So no extra loads. And there is no thick crust on the field in a dry time.

Better to travel 75% full then add 15% water and pay to haul that!

I give up. So are you better to pay someone to suck an extra 10 mins everytime to try and fill the tanker then, rather than throw water in?

Depends on how far you are hauling it and how long tanker takes to fill.

Can see no benefit it just filling a tanker with water just so it's full!

This 75% full thing and at most 90%, there must be a problem in your system. Air leaks at unused doors or holes in pipes will cause foaming which will make your tanker 'trip' too early. Or if you are shutting the door too quick after the fill note your tanker wont be full as it is actually still sucking. When you shut the handle on the door that the pipe is connected to if it gives a little bounce you've shut too soon as slurry is still going up the pipe. When lifting out of the bottom of a tank with a single 7 inch hose, a tanker will keep filling for 15 seconds after the full tone.

100% filled if you topfill. And the lagoon is constantly being mixed to

The slurry has to be right to do the job , the way you guy go about thing blocking up is because the slurry is to thick, & yes to do the job right you need a D/M sensor & this will keep you right & a flow meter , but by the sounds of some post's in this thread all you want do is get rid of it,

Is there a figure for an optimum DM for slurry for nutrient uptake?

No. Vacuum tankers WILL NOT fill to the top. Especially in a deep tank. Ask @Cowabunga. I think I have worked with enough slurry to know that a vacuum tanker wont fill to the top

Calm down , it's only slurry. I didn't realise cowabunga has an opinion on it, then it must be true. So if you and cowabunga can't manage it, then it's an impossibility, OK, I see. One question though, if it's an impossibility, how come tankers all have a double trap and how come the second one always has a little slurry in it?

Ever notice that the sight glass is a foot front the top, so thay you dont realise that the slurry drops down when you release the vacuum and no I dont care either way, I just haul away at it

Yes the slurry does accumulate at the front when filling and normally drops when the vacuum is normalised. However I can fill quite full, not sure quite how much space is left though, when the tractor and tanker are filled on a significant slope with the tractor parked facing uphill. I think like that it must fill to plus 95%.
I know that when the top sight glass blew out a couple or three months back, after filling on the flat, a couple of wheelbarrow-loads of slurry blew over my tractor before the slurry levelled out to the bottom of the sight glass. I guess the glass is about 3" and situated down about a foot from the top of the tank. This was with undiluted dairy cow slurry, not not thin frothy stuff and not too thick either.

In my slurry, as described, I have never failed to fill a tanker well above 75% and I'm raising it about 12 to 15 feet to the tanker full height and reception pit half full mark. A bit less from my other lagoon by about 3ft.

There is.

Are you telling ? Is it a secret ?

It depends who is asking, also who is telling. It depends who is buying and who is selling and just what hat they are wearing - that day.

Some posts on here contain more opacity than others.

Thanks for clarifying that,your secret is safe,I'll keep it under my hat.

The secret is out. Here is a report by Teagasc (pronounced chuggus). Shows that there is indeed a sweet spot for slurry consistency and available nutrients is directly linked to Dry Matter ie. halve the dry matter halve the nutrients.
In my humble opinion I agree with this, there is a balance to be struck between stuff that's so thick that when spread in the field it left it looking like a giant barcode and stuff that is that thin that you would be as well just watering it. Again it would appear that slurry consistency has been greatly influenced by the contractors like the db vs ts debate most of them don't give a toot what good the slurry does or how its utilised, they just want it as thin as possible to be easier on machinery and faster to pump to give them bragging rites on how many m3 per hour they can shift and earn more money, it wouldn't matter to them if it was pure water.

Cattle slurry is affected by DM, though saying that the best cattle slurry I’ve worked with is separated.

Pig slurry can be very deceiving, it can look like grey water coming from the dry sow house and it will burn the leaf in strong sun.

Any views on the Conor dribble bar?
There all over priced. I guess there having the 4k of grant money for themselves
