Digestate from human waste.

larthehar

I am just wondering if anybody has any experience with this. I have had an offer of some and I am not in bord BIA so I am considering it as the soils are low in p and k in some places. opinions/ thoughts?

What on earth? Where do they come from?

I presume he means treated sewage sludge. I really hope so.

If its from an AD make sure it has been pasteurised to minimise disease spread.

By product of a bio digester

Afaik once you’re not spreading it on ground that is going to going crops for direct human consumption(veg or milling wheat) you’re ok to go on.

Are we talking sh1te here? :rolleyes:

Would you not end up with fields full of daisys putting dead bodies all over the land.

One of the least horrendous things that come to mind tbh.

The bord bia regs for producing milk won't allow it either.

Op I presume it's the waste company doing the soil testing? Usually do from what I hear.
Tillage farmers down here are getting to be big users of it.

Edit: I think you'd nearly want to be ploughing it into land say if reseeding etc for grassland farmers.
Less of a risk in picking up something then in the crop.

I use lots of it on tillage ground. Heavy metals are the main bugbear, especially mercury.

Christ.. i just read the title again there.. poor choice of words!!! Mods might change it to waste? Mod. ( Your wish is my command! Done!)

Yes, treated human waste.. fed into the digester. The company soil tests the ground, draws up the nutrient management plan and delivers to the farm..
What about the effects on the organic matter?

The title is fair bad when your relieved that the op is talking about sh1t

There's a Donegal company running a natural burial ground here in Wexford.
The participants have the options of a cardboard box or a wicker basket. Then a tree planted on top.

Could apply to this thread.

Where does all the heavy metal, especially Mercury get into the system?,

Just be careful of the heavy metals as too high a level of certain elements isn't good for the soil.

If it's done correctly they will monitor heavy metals content and soil test for you so as to justify it for waste disposal paperwork.
Spread sludge cake/ sewage mixed with lime that's fairly inert and odourless after 24hrs before osr which ends up in mayonnaise, they love if you have facilities and to store it for a few months not sure of your regs as regards that though.

For your self I'd take nutrient contents they show you with a fair pinch of salt, could be 10/20% high imo.

Take a look at" Biofert" on the Quinn's of Baltinglass site for some information on this stuff, lots of it being delivered around here at the moment

Apparently they test each load of sludge before dispatch for the nutrient managment plan.. they claim that the NPK values are the amount that usable.. again i think that there will be losses at spreading so i would say a reduction of 20% would be a minimum..

Re storage, that was the first question they asked me!!

My gut feeling is that if monitored correctly it should be ok to run with.. have ran a few numbers and with the price of fert it looks attractive..

Is there not issues with micro plastics that is being investigated in the UK because of similar practices?

I reckon you could end up with a **** load of issues...

OP where or what type of plant is it coming from? Heavy metals would be the biggest issue, followed by trace element problems down the road for you. Does your land actually need lime for example?

Never wrestle with pigs

Getting it here this year for the first time. Left bord bia as it's no use to me. 2500g to the acre is equivalent to two bags of cut sward.

Not of the exact plant location, through SEDE.. i am waiting on more information on the actual nutrient make up.. land was soil tested.. pH was a little low and got lime to correct. Land was allowed to grow stemmy silage over the years so sucked all the p and k out of the ground. I guess i will have to wait on more info.. very little online!

I presume that us humans eat a fairly weird diet. The digestate tests high on hormones also.

I take a fair bit of it. Each batch is independently tested and follow up soil tests. It’s from an anaerobic digester and then gets heat treated. Lime is added to 30% and then they spread it for me. Doesn’t really smell but we have to work it into the soil within 24hrs. It’s the only fert that OSR gets before planting. I also use it for maize and other than a pinch of starter that all the maize gets.
