Well you still haven't asked correctly I do not understand post the picture someone here will have an idea for you

[burden]

i need the trees, the horse and the farmer to appear to have the same lighting

I am on itouch but I think the filter levels can help you

While they are all separate image you can try Image|Adjustments|Match Colors, it "Can" (may) get the colors closer to the background image.
Some times it works well some times not so much.

After that you need lots of tools to match.
Hue/Saturation, Selective Color, Clone, dodge and burn, and don't forget you need to add shadows to the added images.

You can also try using FILTERS>RENDER>LIGHTING to simulate ambient light bouncing off the landscape on the object/image.

cheers that seems quite helpful

any shadow tutorials you would recommend

For this image there aren't any long shadows so the burn tool on the ground may be good enough.
Be careful with dodge and burn, set exposure low and take some time to build it up.

There are lots of other ways but this should get you started.
