This question stems from the response to the preceding question. Conventional agronomy does not understand the subtle laws that govern Life, or Nature, and is only interested in that which concerns the most material of physical aspects: mechanics, chemistry, and so on. The word agronomy stems from agros (field) and nomos (law). Does it mean that the agronomist wants to understand the laws of the soil, or to impose his law on the soil?
It is for this reason that the chemical struggle is destined for failure. The solutions it proposes are often against nature. There is no other possible long-term outcome than a worsening of the situation. On the other hand, the etymology of biodynamics expresses interest in the subtle forces behind matter. In German, biodynamic was originally biological and dynamic agriculture. Biological: no need to explain. Dynamic: dynamis, force. Thus, in addition to biological agriculture which refuses products opposed to life, biodynamics studies and uses the forces and laws of the living. Unfortunately these forces are not measurable, but their effects can be observed. Optimising these forces is the aim of all biodynamic preparations as well as dynamised infusions.
