INTERPRETATIONS OF SOIL PROPERTIES AND SOIL CLIMATE IN THE TRANSYLVANIAN PLAIN, ROMANIA

The Transylvanian Plain is an important region for agronomic productivity. However, limited soils data and adoption of best management practices hinder land productivity. Soil temperatures of the Transylvanian Plain (TP) were evaluated using a set of 20 datalogging stations positioned throughout the plain. Soil temperatures were monitored at the surface and at depths of 10, 30, and 50 cm. Soil moisture was monitored at 10 cm. During soil pedogenesis, soil properties and features developed in response to differential lithology and macro/microrelief. Evaluated soils were found to largely be a complex mix of Cernisols, Luvisols, and Antrisols. Soil temperatures of the TP are mesic, with small differences between the northern and southern extents. Differences in seasonal warming and cooling trends across the plain were noted. Influences of slope aspect and inclination are suspected as a cause for local temperature variation on TP soils. Temperature variation has important implications for planting recommendations (i.e. germination temperature, maximum growing season, etc.).
