Displaying Product Description In A Product Scroller

I've got a product scroller showcase block on the homepage, currently listing the featured products (Responsive theme). I've been adding extra fields to the product card such as the sku, quantity, amount, etc. I want to do the same witht the product description, however I couldn't find a way to do so. I've tried everything. In the inspected HTML it shows the product description div, but it is empty.

I've got


and also tried to pull it in with

{assign var="prod_descr" value="prod_descr_`$obj_id`"}{$smarty.capture.$prod_descr nofilter}

including other solutions I've found on the forum, but no luck.

Has anybody got an idea of what could be/could I be doing wrong?

Thank you so much!
