“…The goal is to neutralize the effects of adverse human impact on the ecosystems and to popularize the idea of "feeding the soil rather than plants." Innovations may concern, among others, biological treatment of wastewater, recycling of organic wastes, biological deodorization of gases, purification of contaminated soils (bioremediation of soils), silt, settled sludge, reservoirs, restoration of soil fertility, surface-active substances, and preventing corrosion, zero tillage, as well as biological nitrogen fixation and reduction in the need for chemical fertilizers that can be achieved by cultivating legumes (Materia et al 2015;Ociepa-Kubicka and Pachura 2017).…”
