I guess you’ll need to take the <a> element out of this code:
<h3 class="entry-title">
<a rel="bookmark" href="http://freeindependentsun.com/permaculture/stop-tilling-sheet-mulching-and-no-dig-gardening-howto/">Stop Tilling! Sheet Mulching and No Dig Gardening (how:to)</a>
</h3>
Obviously the code will not appear like that in the template file. The title of the post, for example will be represented by a call to the_title() or, perhaps, get_the_title(). Similarly, the URL will be represented by the_permalink() or, possibly, get_permalink().
Exactly which file the code appears in will depend on your theme. It could be in multiple places (see the WordPress Template Hierarchy).
