A core concept in biodynamics is the "farm individuality."
As Rudolf Steiner explained in 1924: “Now, a farm comes closest to its own essence when it can be conceived of as a kind of independent individuality, a self-contained entity. In reality, every farm ought to aspire to this state of being a self-contained individuality. This state cannot be achieved completely, but it needs to be approached. This means that within our farms, we should attempt to have everything we need for agricultural production, including, of course, the appropriate amount of livestock. From the perspective of an ideal farm, any fertilizers and so forth that are brought in from outside would indeed have to be regarded as remedies for a sickened farm. A healthy farm would be one that could produce everything it needs from within itself.”
