For a basic textured terrain I would start off unwraping your UVW shells then render out that texture map and add some texture in your favorite program like photoshop or something.

A description of your terrain would be helpful, or even better, a rendered image.  Knowing how close to the terrain you plan to be will affect how you create the material as well.  I do a lot of terrains that are primarily grassy lawns, and have a few techniques that I like to use.  But a terrain seen from only a high aerial view will be textured a lot differently than one that is viewed from the height of a person standing on it.

Here are a few tips to start you off.  Your bitmaps (images of grass, or whatever) should tile seamlessly.  If you can't find some, or buy some, there are tutorials out there on how to create your own.

In the Diffuse slot of your material, use Mix maps to blend two texture maps together.  I like to use a Noise map to mix them.  In some cases, I will nest a Mix map within a Mix map to get more variation.  Using the Mix technique can break up the obvious tiling in many cases even by using the same texture map in each slot but one being a different size than the other.  

If you want to get a little more advanced, check out the Composite map.  You can create multiple layers, assign each a different mask, blending mode, and opacity to help vary the rendered appearance.
