The application of nitrogen salts synthesized from the air has the power to negate living interconnections in favour of its own mechanism of action. They tend to bring the physical principle of the temporal succession of cause and effect into force within the life organisation of the plant. That this is so is spoken by the fact as well that, in order to maintain yields, roughly the same — or even increasing — quantities of nitrogen salts must be applied year after year anew. Through the external supply of nitrogen, yields become almost calculable.
