Good lenses for my camera?

I have a Nikon D3000 and really into landscape photography. I just finished a project on black and white flowers. I also do a lot of pictures for my brothers' sports (football lacrosse hockey and baseball).So I was wondering if there were any good lenses that are a reasonable price for me to buy?

Look at the new Nikon 55-300mm VR lens, as it will give you a nice reach for outdoor sports in daylight.

There's loads but if you don't say what you want it to do you are going to end up with people just shouting lens types to do.

The ultimate landscape photography lens is Nikkor 14-24, but since many users can't afford such an expensive lens, Tokina 11-16 is a good alternative.
