HOW TO PREPARE A GARDEN BED USING THE MITTLEIDER METHOD
Before putting any soil in your 36"x8' beds, sprinkle 1 1/2 cups gypsum on the ground. The 36"x8' beds are what I have in the greenhouse and you can plant 4 rows in it. Outside I have 18"x30' beds. Those would get 4 cups of the pre-plant mixture tilled in and 2 cups of weekly feed when the plants are up.
After putting in 1 part sand and 3 parts (or 1 part sand, 2 parts sawdust and 2 parts pearlite) sawdust into your beds until the beds are level with the tops of the boxes, sprinkle 1 1/2 cups of the following pre-plant mixture. 20 cups gypsum(hardware store); 1 cup epsom salts(pharmacy); 1/4 cup Borax(laundry isle). Till or shovel it into the top 6 -8 inches of soil.
When the plants are up, start fertilizing once week with 3/4 c. of the weekly feed mixture. You can buy the micronutrients that will come with the recipe at growfood.com for about $14.
When you know your plants only have a couple more weeks until they are through producing, you can stop the weekly feed. If you plant something else in their place, start with the pre-plant mixture again. Do not put the pre-plant mixture in with seeds. They will not germinate correctly.
