摘要:
A process for improvement of the soil by reducing microbially formed ethylene in the soil by bringing compounds which bind ethylene or of which it is known that they inhibit ethylene biosynthesis between S-adenosyl-L-methionine and 1-aminocyclopropane-carboxylic acid or 1-aminocyclopropane-1-carboxylic acid and ethylene respectively, into the soil zone relevant for the root growth of higher plants and allowing them to act there on the soil microorganisms.
