This picture was taken last February. A leaf tissue test was sent off and then the area immediately sprayed with manganese. The spray made no difference and the leaf tissue test came back low in manganese and magnesium. After advice from Plumbo, I gave it a dose of phosphite, manganese & magnesium. There was an almost immediate response, but a second dose was needed later on. What ever the problem, I think a bit of phosphite in the mix can give the plant a useful kick.

The field was wheat, direct drilled into OSR stubble, on light land. If you look carefully, the drill tractor wheelings can be seen, and also the combine wheelings running at a diagonal to the drilling. The black lump in the picture is top dressed compost!
