Compost Preps BD502 - BD508

The Compost Preps - 502-508  are all made from medicinal herbs. BD502-506 are humus-like, rich in beneficial bacterial life and minerals. BD507 and BD 508 are in liquid form. They radiate cosmic influences and forces throughout the compost heap aiding the transformation of compost material into humus.

Just 1 gram of each prep in a compost heap is enough, in much the same way as a small spoon of curd  in a large bowl of milk is enough to transform the entire bowl of milk into curd.

The biodynamic compost preparations 502-508 are applied to the compost heap when it is first made, and to any compost that is brought onto the farm property to aid and regulate the fermentation process. Experience in India and in many countries of using these preparations in composts and liquid manures, has shown that they accelerate the processes of humus formation, and as such avoid losses of valuable plant nutrients.
