The purpose of this work is the ecopedoclimatic assessment of the Sânpetru Mare area (NV Timiș) in order to develop improvement measures (agrotechnical, agrochemical, hydrotechnical) and improve soil productivity. The sustainable development of agriculture is a strategic priority, being directly conditioned by the quality and health of soil resources. In this context, the efficient management of agricultural land requires a deep understanding of the factors that influence soil productivity. The northwestern area of Timiș County, including the Sânpetru Mare locality, is part of an area with high agricultural potential, but which, in places, faces pedological and climatic limitations. The main limiting factors of the productions obtained on these soils are soil acidity and generally poor supply of humus and mineral nutritional elements. The practice of sustainable agriculture here requires a balance between soil degradation and regeneration processes, of great importance for these pedo-agrochemical conditions, and solutions for protecting and restoring fertility must lead to efficiency, quality and conservation of soil resources. The practice of restoring the fertility of acidic soils has proven that the two specific measures – amendment and rational fertilization – are effective actions for the reconstruction of acidic soils and these two measures mutually enhance their effects. Obviously, amendment by correcting the reaction creates a physico-chemical environment favorable to plant growth, but fertilization uses the newly created favorable environment for restoring fertility, increasing productivity and protecting soils, so fertilization determines a harmonization of the requirements of plant crops with a newly created and improved environment, in terms of nutritional conditions.
