Draining Boggy Land

farmer2018 · 13-05-2018 8:59pm #1

I have to drain about 10 acres of boggy ground with springs in the fields. What is the best/cheapest option? Is that connaught agri pipe a good option?

Open drains and then level the field like the top of a load of bread. Have a fall to each drain from the centre of the field.. pipes in bog arent too succesful and the return isnt in it

What's the soil like?
Was it drained before?
What's growing in it now?
Is there somewhere to drain it to?

It is peaty soil with clay a few feet down in parts.
Was drained last about 20 years ago. All drains that were opened and closed in are all blocked up. Grass and rushes now! There is a open drain in the bottom/sides of the fields.

Having plenty of this land myself I know it's difficult to manage but can throw up serious grass when drained can be great veggie ground too.clean out open drains first.cheapest way is to try get fall to these drains by sloping the ground,heard bad reports of how brittle c agri pipes are,others have suggested make your own with roll of terram and normal pipes,cud be a goer.stones are a wast of money as will eventually block up but on the plus bogland is easy to drain and will improve tenfold

Yes the parts that are dry grows great grass. So the terram and normal pipes without gravel is the way to go you reckon?

The good thing is the all fields can be drained into open drains, the question is the best way of doing it.

connacht agri themselves have stopped doing the pipes but will supply you with the membrane to cover the usual pipes you can buy in any agri stores afaik

Dig a test hole see what the soil profile is like.
If you put any kind of pipe into the peat layer you are burning money as it will have no effect I have learnt from painful experience
Drainage pipes should only go into the soil layer that the water is moving in.
If that layer is below your out let you will have to look at mole drainage but that is seriously expensive.
Every drainage job is different I have found what works in one field might not work in the field next to it.

I'd say it's the best way to go as long as it's black ground gravel is a waist of money others may disagree

Spend the same money reseeding an already dry field will prob yield a better return.

Where can a roll of this Terram be got? Would you use it with 4 inch JFC pipe?

Connacht Agri do not sell that pipe anymore, they are just selling the sleeve which is 12 euro for 6 meters.

Your local farm/building supply shop should be able to get a roll for you

In bog , we dig down till you meet the mud layer .
Pop in a 80 mm pipe , roll out a bale of 4x4 straw .pike it in on top of the pipe . Back fill .use a sewer pipe at the open end .work perfect .has been here for 25 yrs .and watch the water flow when it rains .
Place 3 m apart

got me thinking there, instead of straw would rushes do the same job ? Im guessing they'd be down too deep for any spores to germinate and if would be a good way of getting rid of the ba***rds....

Hard to know who is right, heard people say straw never worked

Does the sleeve only come in 6 meter lengths? I'd love to try it on an acre to see if it works.

farmer2018 · 08-04-2020 10:06pm

Any other thoughts on this? Some drains that were filled with 4 inch pipe and shale are blocked up that were done 10 years ago. Any one with experience on draining this type of ground and have been successful?

Gudstock · 08-04-2020 11:26pm

From what I have seen, for bog or peat ground that was originally raised bog cutaway, if you do a trial hole when the ground is wet you will see how the water collects from the clay layer up into the peat - it can't get though the clay hence why the bog formed in the first place.

You need your perimeter open drains to be deeper than the clay below the bog.
Then your piped drains across the field should have the pipe laid in the clay layer with stone backfill up just above the clay layer just into the peat.
Ensure that the clay dug out is well mixed up with the peat when backfilling so that it doesn't clog the stone you've put in.

When reseeding and after use gran lime only instead of ground, gran won't soften the peat surface like ground does and avoid poaching at all costs.

This type of ground well drained and cared for can surprisingly grow huge volumes of grass.

That seems to me to be the way to go. Just I'd add terram on top of the stones.
Can buy a terram type product called Weed Out (or something like that) comes in 15 m rolls 1metre wide. Cut in half with a hacksaw gives just the right width and easy to handle if there's wind.

Has anybody cleaned out ,or jetted drainage pipe ?
Or is it pointless ?

Not us, but some neighbours do it on large flat fields with I'm guessing flat or poor fall in the drains.
I think the dutch are fans. There are some tractor powered jetters out there.

I discovered old drains in a boggy field. Basically they were all dug by hand, two flat stones either side and a larger flag on top. Water travels along the clay on the bottom. Drains worked perfectly for years, I'd say they might have been there for over 100 years.
Enter the 2000s and the modern farmer in me had the contractors in making round bale silage with those big tractors and made **** of all the drains. field went back to bog and rushes again within 2 years.
I spent a long Summer with a small mini digger reopening and replacing those same drains. Lesson learnt the hard way.

Great insights but how do you drain bog

farmer2018 · 10-04-2020 9:39am

Lads, I am finding it hard to see the whole purpose of a pipe in peaty soil. Will clean stone not just work better?

Clean stone may or may not work. Biggest issue is stone or pipe getting clogged . In the overall budget for a drainage job pipe adds about 15-20% to the cost.

I see you have clay below the big/soil. Open drains will only drain soon much and have to be cleaned every 10-20years. If you are land draining dig drain put in pipe, fill drain to top of clay level and use straw or membrane from allowing peat/disturbed clay blocking drains.

Stone only drains may also work but again using membrane/straw to form barriers to stone is advisable. On stone round sandstone is better than crushed limestone

farmer2018 · 10-04-2020 10:38am

Should you have to be cleaning out open drains every few years realistically? What depth are your open drains in general? I notice any drains that are deep enough that have met stone do not need to be cleaned but other open drains fill with mud/weeds again in no length.

Theres some here with 40 years and never been touched,while others are silted up after 5

Hoping to get em cleared this year,and tap few more springs aswell

Any other thoughts on draining peaty soil? Other opinions welcome on what has worked for people.

farmer2018 · 22-04-2020 7:48pm

I found some old flagstone drains from doing a bit of investigating the last few days. The area over the flag is wet and they are about a half of a foot down from top of the soil. What would be the best thing to do with these try find the mouth and clean it out?

Can anyone help with this?

farmer2018 · 15-04-2021 9:25am

Have opened some drains since last year. I am told to put clean stone and a 4 inch JFC pipe. Is that the way to go?

So you are saying just to use a pipe and no gravel? What has worked for you?
