Qualitative assessment for orchards conversion of some land in Secaş area, Timis County.

This paper aims at obtaining background information on soils and their morphological, physical, chemical and agrochemical characteristics, so as to substantiate the defining scientific and technical quality of an area of 19.00 ha for their conversion to orchards. After a detailed presentation of the landscape (relief, lithology, hydrology, climate, vegetation, human influences) useful to explain the phenomena that occur in the soil and how these phenomena and processes can be influenced by farming, in his work were followed two distinct aspects: of production and the characterization of farmland and elements that help to define the productive capacity of land. From an economic point of view the assessment of land is made by determining evaluation notes according to soil properties (physical, physico-mechanical, hydrological, chemical, etc.) and natural characteristics (geomorphology, hydrology, climate), traits that eventually determine the fertility of the soil and are closely correlated with human activity. Given the complex of climatic (corrected temperature and average of annual rainfall values), technical and edaphic (relief, ground water, flooding, soil reaction in the first 20 cm, edaphic volume, the degree of base saturation, porosity, humus reserve, calcium carbonate) factors in the investigated specific perimeter, in the end was obtained a weighted average evaluation mark for the main categories of land use. ©2012 Author(s) CC Attribution 3.0 Unsuported License.
