Roots look like they're burning off/ leaves going yellow/red

[Binc]

Roots got drilled about a month ago and came up really well, in the last week they have started to turn colour are they short of something?

Picture to follow

Thanks

Either too dry or too wet, they don't like either, assume you got soil tested and fertilised accordingly ?
Mildew and root damage are the other possibilities maybe

 

[Binc]

Good start, will test soil tomorrow to check, also it has rained for the last 10 days [emoji22]

Sorry for the delay

I would guess they were planted by scratching the surface and spreading or drilling . the soil below is waterlogged and the roots cannot penetrate to reach nutrients

I would spin some fertiliser in effort to perk them up, they look hungry.

 

[Binc]

They were direct drilled, lime, p and k before hand

Wet and maybe short of nutrients

Or a foliar application, would it be boron deficiency?

 

[Kevtherev]

Have they had any N @Binc ??

 

[Binc]

No N and we were thinking boron...

Got a similar field here though not quite as bad. The wet patches are worst but none of it is flying. I put it down to being too wet and cold. It was ploughed, limed and had three cwts an acre of 16-16-16 so it shouldn't be lacking in anything. The IR is coming on well though.

There a patch that a bit of a lump that's flying about 30m2 so I suspect the rest is a bit damp! We've had rain every day for the last fortnight so I wouldn't be suprised

I'd say the recent heavy rain, possibly unable to get away from the surface? Roots will definitely need N to come to anything at all, but probably a waste of time if you've left the grass there (as it looks?) as it will swamp the roots out. Presumably that's the old grass, not seeds?

Boron deficiency will affect the bulbs, but it would have to be pretty bad to affect turnips imo. It won't stop the plants growing in the first place.

You need to have killed the grass off before drilling, to apply some N, and apply some dry...... imho.

Could be boron if freshly limed

 

[landslave the 2nd]

I would say looks like waterlogged/Wet feet ...........as others have said they would need some N

 

[Cows 'n grass]

With that purple tinge of put my money on it being phosphate deficiency.

How much fert did it have?

I'd order some DAP while you wait for your soil analysis to come back.

Some N would help, we had a direct drilled field like that into grass a few years ago which looked similar I've got a feeling the agronomist said they were deficient in manganese we ended up spraying them with upstart or something like that
It seemed to cure them though
