Driven by an increasing demand for GMO-free soya as food or fodder, the production of organic Soybeans increases, also in high latitudes. As a legume crop, soya needs
specific rhizobia bacteria to be supplied by biological nitrogen fixation (BNF). Since most soils lack the soy-specific strains, bacteria material is usually added manually. We set up a field trial with 5 site-years to investigate the benefit of this inoculation procedure in two different environments (humid, Germany/semi-arid, Russia) under organic farming conditions. Overall 5 different varieties were used (at each site 2 individual and 1 joint) to compare inoculation against untreated control. Leaf
chlorophyll as indicator for BNF was determined by a SPAD-502. To make the SPADmeter readings of diff d). Inoculation was always significantly successful and led to higher leaf chlorophyll contents. This positive inoculation effect resulted only in 1 year in a higher bean yield.
Since soya will only benefit from BNF after manual inoculation, this additional effort seems to be necessary to substitute other pules in organic crop rotations.
