Does the field usually receive a manganese spray, could you put up some pictures? What is the soil type? Lots of wheats on heavy soils look awful.

Try and get a photo of a good section of the field, particularly of any darker green parts plus a few photos of individual plants showing the young and old leaves.

Are you sure it’s mn ? Leaf tests taken ? What has been applied product wise / forms ?

A soil sample would be irrelevant for manganese.

Crap roots?

 

[T Hectares]

Has it been rolled in the spring ??

No

 

[nelly55]

Not been flooded ,light sandy/ loam soil.

Previous crop?

Maybe sulphur

 

[clemmo]

My bet is sulphur / magnesium

 

[Luke Cropwalker]

Hard to tell from the photos but I suspect Magnesium deficiency. Have you experienced Magnesium deficiency previously in the field? Has the crop recently had a big dose of Potassium? If the crop were mine I would probably get a decent dose of bittersalts on ASAP, but perhaps leave a small untreated area as a control. Some sunshine might be all it requires.

Looks more magnesium to me. Quite stripy between the veins.

 

[Bigjon44]

Sandy soil could be problem. Mine always look paler on the sands after chucking everything at it

Magnesium

Water, shadow rooted

Magnesium def. Light/sandy soils notorious for this. May be more pronounced in areas where seed/soil contact or rooting is poor or a pan is present.

Yara MagPhosK for you in future. The phosphate will also be useful in a cold spring as it gives the roots a kick in the arsh.

The stripes on the leaves show mag deficiency
