Abstract:

The main priority of agro industrial production has always been and remains to provide
the global population and its yearly increments with food food. The issue of soil fertility improvement is still the most important task of agricultural science. The assessment of the agroecological condition of Albic Stagnic Luvisol using carbon dioxide emission, redox potential, and biotic activity was carried out, based on modern methodological approaches, such as soil quality evaluation via ecologically-related biological parameters. Carbone dioxide emission, redox, and biological processes in long-term stationary experiment depend on the degree of soil acidity reduction. Soil acidification can be minimized through chemical melioration with the combined application of different doses of mineral fertilizers and manure. It was found that carbon dioxide emission is optimal in an organo-mineral fertilizing system with application of 10 t of manure per 1 ha and N65Р68K68 with lime dose (2.5 t ha-1) calculated according to pH buffering capacity. It is due to oxidative and moderately oxidative conditions created. This organo-mineral fertilizing system also increases the number of aerobic bacteria and overall biological activity. The mineral fertilization and the use of Albic Stagnic Luvisol without fertilizers are accompanied by increased mineralization, growth of reductive processes, and the number of moulds. Studies have shown that it is advisable to include CO2 emission, redox potential and biological activity along with physicochemical and agrochemical soil properties to assess the influence of different anthropogenic loads on soil formation.
