Pig muck value

Cobblers · Nov 27, 2020

Appreciate this question has probably been asked before but here goes .
My neighbour is setting up a pig B and B business next to a block of arable land that I rent .Will be around a 1000 pigs on a straw system .
I am going to sell the straw into him by the bale
what value do you put on the muck ,sat in a pile on his pad ?

Who knows , why not just swap straw for muck ?

Any blackgrass in it?

Cobblers · Nov 27, 2020

It will be all my straw going back in and the land is clean of BG , you need some idea of values so the swap is fair ,hence the question .Straw making big money this year .

I was told by a boy doing pigs that he got the local Ag college to price his cow , and pig muck for the same reason. £50-55 for cow muck, 60-65 for pig muck.
That was 3 yrs ago!

I think it’s a case of looking at it long term - if you are bemoaning that straw is worth a lot this year then I reckon it’s going to be a short term arrangement. Accept that over the years the straw price will average out but the benefit you get from the muck on your ground will be worth far more in my opinion.
I’d say go for a straight muck for straw deal - one of you lugs the straw, the other lugs the muck.
Iv you insist on valuing it- I think they reckon on 750t of muck per year on this system for 1000 pig shed - I’d say a value of £8/t in terms of N, P, K.

You put in all the straw required, you get back all the muck it turns in to, pig man sorts the baling and leading (or pays you to do it) and you do the muck hauling and spreading. Does it really need to be any more difficult? For a long term agreement it’ll level itself out

Many thanks ploughman and I am Taking the long term view ,just trying to get a fair deal for both parties ,straw will be back to normal come harvest .Currently buying in chicken litter @£14 ton but the pig muck would definitely give the ground more OM

Thanks Rob ,even simpler

We have just such a unit and are lucky that we have our own straw but I value it on a straw for muck deal as above with equal value on both sides. I do 'value' the benfit of getting that muck though.

I do a straight swap. He pays for baling and carts bales, I cart muck and spread it .
I know I’m only getting my own straw back regarding weed issues.
if it’s right next door it’s much more attractive . Ok, this year I could’ve made a fortune selling the straw, but it evens out over the years

It never fails to amaze me how people always want to complicate something so simple.

I don't see why it has to be anymore complicated than lend the pig man your straw, he bales and hauls it and when his pigs have finished with it he gives it back to you and you haul it out and spread it. Simples.

The amount of times I've heard of farmers arguing because they think that the other party might be tuppence better off out of a deal in a given year is ridiculous.

No I didn’t. I wasn’t looking for a cost. But @Cobblers was.
I have pigs, and do a straight straw/ muck arrangement.

Nutrients in pig FYM are basically a total amount for each nutrient and a 'crop available' amount:

Nitrogen:
Total N: 7 kg/tonne which can be between 5% and 15% available to the next crop (which actual % depends on soil type and timing of spread).

eg. By applying 25t/ha you'll spread 175 kg of total N/ha, of which between 9 and 26 kg N/ha will be available.

Phosphate:
Total P: 6 kg phosphate/tonne and if P soil index is 0 or 1 then take the availability as 60% of the total and if index is 2 then take 100% as available.

eg. A 25t/tonne application supplies you 150 kg Phosphate/ha of which you should use either 90 kg/ha or 150 kg/ha as being available (depending on the soil P index).

Potash:
Total K: 8 kg potash/ha and if K index is 0 or 1 then take 90% as being available and if index is 2 then use 100% availablity.

eg. 25t/ha application supplies 200 kg total potash/ha of which 180 kg/ha is available at K index 0/1 or 200 kg/ha at index 2 and above.

I've not bothered with sulphur or magnesium....... there is a small value there too.

For P and K the amount that you don't count in the fertiliser value calculation ie. difference between available and total will be there in the soil and you'll pick that up in future years soil sampling. So really you're best valuiung the total P and K value of the FYM.

Value per tonne???

Available N = around £9/t
Total P = around £3/t
Total K = around £3/t

NPK value = £15/t

Farms that used to keep pigs used to get massive yields, they don't anymore, same if not higher intensity of management.

HarryB97 · Nov 27, 2020

Charging him is ridiculous unless you don’t like him. Do a straw for muck agreement then you both get what you need, good neighbours are worth more than a bit of money. If you need the straw money to help cover the rent then you’re paying to much and should give up that block.

How would that compare with chopping and leaving the straw there as postash price wise?
