Possibly a nitrogen deficiency. A little Miracle Grow around the tree
wouldn't hurt. It is generally not a good idea to have grass, or
anything else growing within the drip line of the tree. It takes
energy away from the tree.
Yellow leaves could be indicative of a more serious problem. If the
leaves turn this color in the fall, this could be a sign that the tree
is going dormant or dying. Check the base for entry holes of borers.
You did not give your location and type of soil, which could give
more clues to the problem. Did you get a lot of rain this year,
and does your soil drain well?

Hmmm ...
Not having any plum trees, so I am not expert.
I lean toward iron deficiency.
The yellowing of leaves is called Chlorosis in normal green plants.
http://en.wikipedia.org/wiki/Chlorosis
As for using "liquid nitrogen" requires careful use!
In a science class "liquid nitrogen" was used to dip a rose in it and
then smashed on the table. The rose shattered like glass :)
Very Cool Huh :)

This year has produced chlorosis in a number of sun-loving plants and
those that don't like wet feet.
It has been overcast wet and cool (for here) all spring.
So far "summer" has been a little better. At least we're getting some
sun, a bit less rain, some higher daytime temperatures and the long days
are helping a little.

The article you referenced says that iron chlorosis usually shows up
on the younger leaves first, then the older leaves. This might
indicate their other suggestion of manganese or zinc deficiences.
I would still not rule out other possiblities, like over watered roots
or the tree going prematurely into dormancy because of some disease
or insect damage. The original poster has left out many details, like
is this yellowing on all branches, or just certain ones, etc.

Thanks for all the replies, I've been away the last few days. I'm based
in the UK, Midlands. So we've had some heavy rain recently, but also
allot of sunshine, for the UK at least. The soils is a little sandy, so
drains quite well. The yellowing of the leaves is not on this years new
growth at all & mainly on the older leaves. I've also noticed this
morning that a few plums have dropped also.
My idea of lack of nitrogen was based on a quick search on goggle, as I
didn't think it was water logged & got plenty of water.
I did mean a liquid fertilizer that also contains nitrogen. I don't
plan to have my plum tree cryogenically frozen.
Thanks

If you have other similar plants nearby with or without the same
problem, it could be a soil deficiency of minerals. Here in the
USA, we have a product called Miracle Grow, a liquid fertilizer,
but you must have something like it in Britain.
The tree may be in trouble for other reasons. Check for insect
attacks (borers at the soil line). Again, is this on all branches
or just particular ones? This could be a climatic thing, and if
so, the tree should come back ok next year. Are there any
damages to the leaves besides yellowing, and does the fruit
look normal? The web site posted indicated that older leaves
turning yellow was a possible sign of zinc or magnesium deficiency.

Why don't you take a sample to your nearest nursery and ask them what
they thing. Maybe the local secondary school has a biologist. Maybe
there is a college or university near you that is familiar with your
regions flora and fauna, huh?

Gee, he could have saved a lot of time by just bypassing this forum
and going directly to his nearest 'experts' location. This to me is
just a cop out when you have no knowledge of the subject matter.

Yes. He could have saved time. That said, having some knowledge makes
for better questions.
Halo's follow up contained, "The yellowing of the leaves is not on this
year's new growth at all & mainly on the older leaves."
Let's assume that he means the older leaves are on previous years' wood
and not, last year's leaves carried through the winter and still on the
tree.
That suggests, as you suspect, some kind of trouble on, in, or inside
the tree and not an environmental, nitrogen uptake issue or soil
problem, though it may be that the soil is also in trouble.
Given we can't go have a look at it, consulting with a reputable local
expert or two to get a diagnosis seems reasonable to me.
I don't know about anyone else, but I would be loathe to feed anything
but compost to a distressed tree until I know what's going on with it.
Even then, compost and other organic amendments.
