Chicken muck

[quattro]

@EagleEye Was the Broiler muck ploughed in direct behind spreader? First year using layers muck here, have got sample tested and and back at 3.9% N. Unsure about how much to bank on with losses and unavailable N etc, don’t want hungry crops but definitely don’t want flat crop either!!

If it’s dry, I spread it on top of ploughing/press in front of one pass

was planning of applying 5 tonne/ha ahead of spring barley, either ploughed in or disced in directly behind the spreader. With the value of experience (which is usually learned the hard way and is always expensive ) how much N should I be allowing for in that application? This will be layers manure so no bedding material in dung. Im presuming the bedding material in broiler litter means some N is slower to become available? Thank you in advance

Have a friend whos had layers manure with no straw and had blackgrass in it. Presumed to have been in the chicken feed i wouldnt be worried about volunteer barley/wheat etc in it.

Proper broiler litter is rocket fuel. 1t/ac a lot spread, vs maybe 10t/ac of straw based poultry muck

@Sean Foley, just checked our broiler analysis and it was 3.5% total N which equates to 35kg per tonne we put on 10t/ha so that was 350 kg ha. unsure how much was available but from how the crop grew (spring barley) I would guess it was about 120-130units per acre or 160kg/ha
so looks like 50% available. 5t/ha looks modest but you have more N so a good start.
Dont panic at tillering and lash on more N it can really take off in may/june as muck kicks in

understand the zero risk to the crop, but have had cases of foxes or dogs carrying chicken carcases onto adjacent grass fields with stock in them

You would hope neighbours would be neighbourly when deciding when and how to apply the product and mitigate this in some way.

Broiler and layer litter is very potent stuff. I cannot overemphasise the need to apply it sparingly and accurately. As others have said, 10t/ha (4 tonne/acre) would be reasonable. You may find in subsequent years you can dial this back a bit. Some will be surprisingly available, the remainder will kick in over the coming months. As the soil warms and the bugs get to work, they will convert the remaining nitrogen into more available forms. You may see further benefit in subsequent years.

Dosnt seem to be 2 sample sheets the same for comparison , i dont think they got this right as 40t/ha would be off the scale!!!!
12t/ha would be max from what im told , this is layer muck .
As weather was so good we ploughed after beet and drilled skyfall in cracking conditions with DAP rather than spread muck on it , will probably leave chicken muck to go on before osr in summer.
Spreading man reakons too wet to put on growing wheat unless we can mix it really well with compost.

I'm confused by that table of yours but my brain is on strike today. I'll have a fight with it later when I've a calculator to hand.


EDIT: coffee/brain stimulant on board now. Their excel sheet is clearly borked.

If they are reporting 6.06 kg N, 6.10 kg P and 3.55kg of K in a tonne then they can't possibly reach those figures in the second column.


Applying your manure at 10 tonnes/hectare would give you:


60.6kg/ha of nitrogen.

61kg/ha of phosphate

35.5kg/ha of potash



The results are interesting because this layer muck, in contrast to most other manures (at least if memory serves me correctly) contains twice the N and P as it does K which is almost 'backwards' compared to other manures where you'd expect to get a bit of N, a bit of P but a lot of K.

The sheet is correct, but a very arse about face way of showing it. The 2nd column is the result of applying 250 kg N, an unusual way to portray it. I think it would take a brave man and perfect spreading to dollop that amount of N on in a single hit from a single organic source.

That seems a lot. 350kg of organic nitrogen based on manures would be over the field limits here I think.

Okay so it turns out the sample result is quoted on a dry matter basis. So not as potent as first seems. Pity they didn’t make it clear on the sample result! Dry matter came back at 31%

I think thats why my analysis looks different to other samples , according to that its 19% dm , leaking wet but will be ok mixed with compost

Ah ok. So reduce the figures in your fresh material by 69%?
