The role of pedological information in the definition of land productivity and potential pressures on soil quality from Timis county.

Soil properties can exert a decisive influence on the development of the root system, mineral nutrition, providing air, hydric and thermal regime needed to carry the main physiological processes in plants. In turn, it acts both directly and indirectly on fertility (quality) status of soil. Systematic mapping and agrochemical soil studies conducted by the Office of Pedological and Agrochemical Studies from Timis county provides valuable data on the state of soil quality, the establishment and implementation of differentiated crop technologies, and determining the suitability of land for various crops, substantiation of land improvement works and improvement technology, organization and systematization of land. This paper provides basic knowledge and methodological elements to assess and characterize the natural and anthropogenic resources, hoping that the information presented will interest the decision maker in the future, the agricultural research and practice with respect to environmental protection, to strive for development interdisciplinary studies, because we cannot speak about a healthy environment without an healthy soil. The issues addressed refer to an area of 869,665 ha of which 697,143 ha of agricultural land, included in the National Monitoring Program for Soil-Land for Agriculture in Timis county. The importance and originality come from the need to protect the edaphic cover and environment by: accumulation of scientific data necessary to support certain technologies of conservative work and sustainable management of soil and water resources by implementing conservative systems work and sustainable management of the physical-geographical and edaphic factors from Timis county.
