dock control in grassland

[Derrick Hughes]

Would like to see a link to that trial work as find it very interesting.

I never get to see the results , confidential I expect , they have around a thousand small potato plots as well testing for Blight , you can see a massive variation in those but no idea what they use
Ibers used to test phosphates here , or Ibers that was then 40 years ago then Adas took over the plots

 

[Derrick Hughes]

One thing I remember that came out of the studies was that a lot of West Wales soils have a high Iron Ochre Content , the brown stuff that blocks drains , especially the plastic type ,not so much the clays , anyway this can have the effect of locking up nutritients especially Phosphate, they achieved a lot better response with quick acting phosphates rather than slow release ,

Hate it when the dog Jumps in stuff like that!

Ploughing the spud plots today , I'm away on holiday but will get some when I'm back
It was Trawscoed EHF who used to run the old trails independent , Adas trails are now company funded , which we all know

Mine waste from a good old Devon farm.

Any photos ?

Google image of some of last year's , each of this striped is devided into 10 ft plots
The green ones on left are phosphates and potash plots

Gives the sheep dogs a good colour as you can imagine!

Plenty of springs round here like that , but no mine workings - Iron oxidising bacteria.

Tin & arsenic mining gives us a few dodgy patches.

Plenty of lime and organic matter like compost muck will combat it

Why don’t you direct drill the spuds Derek ?

Utter rubbish ochre affects clay and plastic and don’t even argue with me about land drainage.

2 Foot deep orche

That's a aller pole used for drainage pre even stone drains.

Will block pipes here for a pastime!

I'm not arguing just having a polite conversation, a very experienced land drainer told me that the ribs in plastic pipe Couse ochre to stick more also gets though the slits easier , clays filter it out a bit , but leave it at that I ain't out to Couse any offence at Easter ,

 

[Derrick Hughes]

rubbish

You confusing two points , drain blocking and locking up phosphates , it was the Adas field officer that told me it was locking up phosphates and to keep the pH well up and put plenty of muck on , no help with the drains though , guy is dead now so I can't really go back and argue with him

 

[Derrick Hughes]

But to risk being shouted at again , there is plenty of published info to state that ochre sticks 20% more effectively to a plastic pipe than a clay , we have many clay drains still running put in before we could get plastic , most of the plastic have shut down completely

You might be right, we have 4 inch clay pipes we put in 48 years ago that are now virtually blocked with ochre
