Need sidebar text widget to contain (static) content for each page.

This is my second attempt at creating a WP site. I am using WP 3.2.1 and ATA 3.6.7 as a CMS The content will be changed 3 - 4 times a year by a non-technical office worker. (the site consists of only pages). The site is lombardofarms.com I want the sidebar to contain unique content for each page. For example, the "fresh produce" page would list the current, in-season produce. The firewood page would list the price of a cord, 1/2 cord, etc. of firewood.

I expected to be able to load content to each sidebar on each page in a fashion similar to how I load content to the main section.....but I can't seem to do that. The sidebar content seems to be associated with the entire site instead of a single page in the site. Help! What did I do wrong? Or what am I missing?
