The simbiosis nitrogen-fixation as a factor of ecological safety and soil's fertility

Abstract

The possibility of simbiosis nitrogen-fixation's increasing by biopreparation treatment as a factor of ecological satety and soil's fertility has been studied. Endogenous hormones dynamics in beans treated with biopreparations albit and rhizotorphin has been traced back. The correlation between content of different phytohormones in vegetative organs of bean's plants and nitrogenasa activity has been revealed.
