In a nutshell ...
... Considera collects and organises experiences from growers who have applied biodynamic or agrohomeopathic preparations. These experiences are then presented as a materia medica within which preparations are listed with the issues they address, and as a repertory within which issues are listed with the preparations that addresss them - so this is probably where to start if you have an agricultural problem.
Considera also curates the literature relevant to these efforts, and discusses the practice and implications of such approaches.
Considera previously collected and scrutinised experiences from planting by the stars and from peppering to reduce pest problems. Neither initiative caught on so have been mothballed and further data submission is not invited.
Here is a one minute video guiding you to the active parts of Considera.
