I have not used specific biodynamic preps, I try to read signs in the soil and plants and supply what seems neccesary. If you are composting in place or sheet mulching (sort of the same) you need sugars, that is a definite. I like using mollasses, you can dillute it with water or tea, somewhere around 10:1 to 15:1 depending on what your soil life looks like, active or inactive. Just small amounts of sugars at a time are needed when your soil is looking fairly active. I use yarrow, comfrey, stinging nettle and chamomile as my main herbs for teas.
If you have any specific questions, just ask away. There is an awful lot of info on the subject, and many people do things differently. I am a commercial grower implementing permaculture techniques and what is called biological techniques. Growing at this scale, feeding lots of people, it is difficult to use permaculture in every area. Permaculture is patience and trust in nature's way, commercial growing gets closer to humans pushing a little harder and maybe even rushing things a bit. Composting in place, this is one of the things I'm talking about: if you start throwing lots of compost out on your beds, this isn't nature's way. It probably won't work out without the right variety. Nature grows then withers in place and it happens slowly. This is what you are mimicking when composting in place. Now, you can push it a bit, but it takes patience still. I hope I've been helpful.
