The Influence of Slope Morphology upon the Thermic Regime of Soil andManagement Practices in the Transylvanian Plain.

The aim of this paper is to establish the influence of the relief elements of versants in the Transylvania Plain and of climatic factors on the thermal regime of these soils and on the agricultural management measures. Through its components - precipitation, wind, temperature - the climate represents the most active external dynamic agent, causing the emergence and development of the land degradation process in this area. In order to determine the influence of the climatic factor on the agro-technical characterization of land according to slope morphology, 11 HOBO Micro Stations have been implemented from April to October 2011 in the locality Căianu, with various altitude at exposure coverage. By analyzing the data recorded during April-October 2011, we obtain a similar situation of the southern slopes as compared with the south-eastern and eastern versants - 43.8 mm less rainfall, higher temperatures by 0.37°C in the air, by 1.91°C at 10 cm, by 2.22°C at 20 cm, and by 2.43°C at 30 cm soil depth compared to northern and north-western slopes. These issues, supplemented by those connected to slope, require special agro-technical measures generated by the Transylvani an Plain topography. [ABSTRACT FROM AUTHOR]
