Abstract
The aim of this study was to assess the influence of selected biostimulants (Tytanit, Rooter) and foliar fertilisers (Optysil, Metalosate Potassium, Bolero Bo, ADOB 2.0 Zn IDHA, ADOB B, ADOB 2.0 Mo) on the activity of dehydrogenases, acid and alkaline phosphatases and catalase, and their influence on the level of biological nitrogen fixation based on the nitrogenase activity in soybean cultivation. Between 2016 and 2018 a field experiment was conducted at the Gorzy Experimental and Educational Station, Pozna University of Life Sciences in Poland. During the three years of the experiment the foliar fertilisers and biostimulants significantly stimulated the catalytic dehydrogenase activity (DHA) and alkaline phosphatase activity (PAL) in all the experimental variants, as compared to the control variant. The analysis of the results of acid phosphatase activity (PAC) during the entire soybean growing period showed that it decreased significantly compared to the control variant when Tytanit, Rooter and Bolero Mo preparations were applied. Additionally, the analysis of catalase activity (CAT) revealed that apart from Tytanit, all the preparations significantly stimulated this enzyme, as compared with the control variant. The field analyses of biological nitrogen fixation showed that the fertilisers and biostimulants significantly stimulated nitrogenase activity under the soybean plantation.
