Yes, that sounds like a good product. I have used packaged soil (the Miracle Grow brand) for raised beds with great success because the ingredients you list will create what you think of as "soil" once they are watered and the manures and other animal and plant products begin to grow and feed on the inert ingredients. Worm casings, bat guano and the other things you mentioned in the ingredients contain millions of soil making life forms and these all work together with organic matter to support plant life. You can also use the bagged soil half and half with your own native soil to fill your raised beds. Just know that you can still improve the soil mix with fertilizers, a mulch, and amend the soil each year with organic matter such as manures and compost.  Enjoy your raised beds and spring planting and I expect you will have a bountiful harvest this summer. Keep growing, Marianne Binetti
