Others ...Dennis Klocek has made some investigations into drought protection as have BDMax and Steve Storch. (See also preparation 500 for drought tolerance.)
Maria Thun has developed Barrel Preparation/CPP/Fladen, a 'manure concentrate', as an intensification of the compost and 500 preparations to assist the the conversion of organic matter. Thus it is used when manures are spread or green manures are worked into the soil. It introduces basalt and eggshells alongside the compost preparations in the manure. This has been thoroughly tested when made at different aspects of the sidereal Moon.
Max-Karl Schwarz developed the 'birch pit preparation' for biodynamic agriculture to activate humus building in compost heaps and slurry pits. It has also been used directly on plants with 'increasingly good results'.
Nicolaus Remer's 'Sammel preparat' is a dried product from cow manure with the BD preparations. It is used at 30g per cubic metre on raw manures and beddings. it helps the 'soil to cleanse itself and any pathogens present are killed, digested and processed.'
In the 1930s, Ehrenfried Pfeiffer made his 'starter' from 56 strains of microbe cultured with the BD preparations as a compost and soil inoculant.
Mäusdorfer preparation is a dried mixture of the birch and barrel systems mentioned above. It is used to improve the fermentation process in all organic residues.
Donna LaPre has made flower essences fro the Earth which she calls 'Earth Essences'. Elizabeth Backhouse has made a series of preparations culminating in VitaFons II - a 'numinous essence' with formulations for the land. Barbara Scott has made a series of 5 essences for the Earth. Bach Flower remedies can be accessed here.
There is a huge amount work being done in South America. Radko Tichavsky is working in broad-scale agricultural settings with his holo-homeopathy. There are professors of agrohomeopathy in at least two universities with laboratories, greenhouses and students.
Considera would love to be informed of other preparations.
