Responsible use of groundwater resources should be the responsibility of every person, because our very existence on Earth depends on these invaluable resources. Due to the climate change we are currently going through, drinking water resources are becoming less and less qualitatively affected due to pollution and the infiltration of pollutants into groundwater. In agriculture, one of the major causes of groundwater pollution are chemical synthesis substances, which are used as an input for plant growth, for phytosanitary treatments against insects and phytopathogenic microorganisms and for weed removal. That is why the research direction that we approached was that of the responsible use of groundwater and the obtaining of ecological fertilizers based on plants from the wild flora of Romania. In order to obtain the ecological liquid fertilizer, we used plants from the wild flora of Romania, namely nettle (Urtica dioica), comfrey (Symphytum officinale) and horsetail (Equisetum arvense). We tested the organic fertilizers we obtained in the laboratory to see their ability to stimulate the germination and growth of bean seedlings (Phaseolus vulgaris L.). The organic liquid fertilizer we obtained had a very good effect on stimulating the germination and development of bean seedlings. The groundwater sample was taken from the family well. The drilling is at a depth of 40 m and is located in Crucea de Piatră, Călugăreni commune, Giurgiu county. The groundwater sample was transported in a refrigerated box to the laboratory of Ecology and Environmental Microbiology within the Faculty of Land Reclamation and Environmental Engineering within the U.S.A.M.V. Bucharest. In order to achieve the proposed goal, the groundwater sample taken from the family well was analyzed in the laboratory of Ecology and Environmental Microbiology from an ecological point of view. The experiments performed and presented in this paper represent a part of the studies performed for the bachelor's thesis.
