This paper aims at collecting, processing and interpreting the scientific information necessary for assessment of areas vulnerable to nitrates pollution in the lower course of Bârzava River and originates in the current scientific and practical concerns to identify and develop an integrated management of agro-ecosystems, agronomically effective and with low energy and financial resources and, at the same time, ecological and conservative for soil and environment. Data in this paper are the result of studies and researches carried out between 2014-2015, in the lower course of Bârzava River and are part of the doctoral studies and research program PSDRU/159/1.5/S/137070 (2014) of the Ministry of National Education, Romania, co-financed by the European Social Fund-Investing in People, within the Sectoral Operational Programme Human Resources Development 2007-2013 with the topic “Studies and Researches on Assessment of Pollutants’ Impact on the Biodiversity in the Lower Course of Bârzava River”, researches being conducted simultaneously in the field and in the laboratory. The researches of this Project consisted in collection of scientific data regarding evolution of certain components in the productivity of agricultural ecosystems so as to ensure specialized technical support to government authorities, in the areas considered, for development of the “Local Action Plan regarding nitrates pollution from agricultural sources”, this being a focal point of action in implementing the Nitrates Directive for soil and crops and in implementing advanced systems for the use of ecopedological and anthropogenically induced systems. Research of ecopedological conditions and ordering and processing of data are based on the “Development Methodology of Pedological Studies” (volumes I, II, III), prepared by I.C.P.A Bucharest (Bucharest Institute of Research in Pedology and Agrochemistry) in 1987 and the Romanian System of Soil Taxonomy (SRTS - 2003, 2012 respectively), while the maximum limit of nitrates in water is based on STAS No. 1342/77. The objectives and activities posed by this paper fall within the current concerns of international and domestic agricultural research and practice, intended for the study of relations between ecopedological conditions and agricultural land productivity. The novelty and importance of the topic addressed come from the need to set up a database regarding the risk of environmental pollution through various socio-economic activities, the risk management that contributes to the development of the national monitoring network and the identification of vulnerable areas, with rational use of natural renewable resources (soil, water, biodiversity).
