The aim of the study was to compare soil respiration depending on different agricultural practices before sowing maize (Zea mays L.). Results were derived from field experiment that carried out in 2013-2015; research indicates depends cultivation method. highest recorded monoculture using full tillage. simplifications caused a decrease respiration, especially direct sowing. lowest level this parameter Compared with other treatments, such as sowing, reduced tillage and crop rotation, higher by 65, 55 12%, respectively. statistically significant differences tested observed first date measurement all years study. values noted autumn. yield correlated but stronger relationship between grain than straw yield. simple regression analysis showed no linear evaporation, changes moisture biochemical parameters dehydrogenase activity, acid alkaline phosphatase.
