Summary

The influence of biochar with an amount of 0 to 20 t/ha on growth, yield and ingredients on soybeans of different variants was compared. Differences between the variants until blooming could be found. Plants from the HTC variant have shown significantly longer stems than others. These differences diminished until the harvest. Due to extrem low precipitation values in spring and early summer, no rhizobia could be developed and nitrogen fixation for the soybean was impossible. The plants could only use nitrogen from the soil. As a result, plots prepared with mineral fertilizer have shown the significantly longest plants, highest mass of dry matter and highest yields. Further, HTC variants have shown the lowest values in oil- and sugar contents. The
highest value in sugar content was measured in the variant with mineral fertilizer, but did not differ significantly. This results show, that due to the lower amount of available
nitrogen in the year of application there can be a negative influence of biochar on the yield.
