Effect of Different Tillage Systems and Soil Biostimulants on Agrochemical Properties and Intensity of Soil CO2 Emission in Wheat Crop

In this study, a field experiment was performed at the Experimental Station of Vytautas Magnus University Agriculture Academy in Lithuania from 2018 to 2020. The researched soil comprised carbonate deeper gleyic leachate (IDg4-k) (Calc(ar)i Endohypogleyic Luvisol) (LVg-n-w-cc). A two-factor on spring and winter wheat. Factor tillage technology; factor B use biostimulants their mixtures (Ruinex, Penergetic, Azofix). experimental fields were arranged randomly four replicates. aim work assess CO2 emissions, carbon, nitrogen, humus, humic substances using two different management methods (no till—wheat straw left surface; reduced till—soil incorporation wheat straw) or nitrogen fertilization. humus content remained sufficiently stable slightly decreased when retained single-component biostimulators Azofix, Ruinex, Penergetic used. contrast, continuous application combined with two- three-component these biological preparations compensatory increased. Compared initial state, it increased by 1.4–12.8 % due improved complexity extra conditions for microbiological biodiversity. Meanwhile, after three years investigation, technology did not significantly impact content, total emissions. Tillage technologies had significant water-soluble carbon. Under no-till, carbon an average 9.0%, under tillage, only 2.3%. It is likely that combination no-till catch crops stocks soluble C soil. indicator all biostimulants, especially mixture effect two-preparation also more pronounced than single component. results over show promote release mobile acids better decomposition. same organic content.
