This provides two bags. You sinply mix one of these bags with your 25 lbs of fertilizer bought from Lowes, Walmart, Home Depot, etc. They recommend 13-13-13, up to 19-19-19. Most people buy fertilizer anyway for the garden, so this really isnt an extra expense. Also add 4 lbs of Epsom Salts which can be purchased at Walmart for a little under $3. This will make up your "Weekly Feed" which will be applied weekly at a rate of 1/2 oz per linear foot in an 18" wide bed. So not a lot required.
Then for your "Pre-Plant" mix, you will use 40 lbs of lime or gypsum, depending how much your average rainfall is. If you get more than 20 " rain per year, then you apply Lime, If less, then apply gypsum from the concrete department of your home improvement store. add this to 2 lb of Epsom salts, again under $3 for 4 lb bag. also add 1/2 lb of 20 Mule Team Borax for the boron , which can be found at walmart or other stores in their laundry supply area. for about $4 for a large box.
Now for the "Recommended". Most will recommend you purchase the "Mittleider Gardening Course" book. For a full understanding of the program. It ranges from $14.95 for a downloadable E-book, to the $19.95 paperback book. some people like that they can take this in hand right to the garden with them.It can be found HERE.
Others like the wonderful SEARCHABLE pdf version which is $59.95. It can be found HERE.
So for a re-cap you need:
20 Mule Team Borax.....about $4
Epsom salts...................about $3
Fertilizer...for 40 lb bag..........$16.99
Micro Nutrients..... ...............$13.95 plus shipping
Lime ( or gypsum) for 50 lb.......$3
So for around $40 you can fertilize your entire garden (depending on size) for the entire growing season. Plus reap the benefits of healthy, strong plants, and dramatically INCREASE your production from the vegetables and fruits you plant. Making the little expense more than worthwhile.
As for raised beds, you dont HAVE to make raised beds or use the soilless mixes, just plant directly into your current garden soil. You also dont have to have the irrigation, you can just water by hand. So why not test this method out for yourself?
