Research areas

The scientific research of the didactical and scientific personal from Pedology and Ameliorative soil science discipline was conducted for studying the influence of the amelioration works on some physical, chemical and biological proprieties of the improved soils.

The main aspects the scientific research was conducted in the following directions:
- characterization and description of the morphological, chemical and physical proprieties of the soils affected by excess of humidity (pluvial and phreatic), excess of soluble salts (NaCl, Na₂SO₄);
- amelioration of soils affected by humidity excess (drainage and subsurface drainage works associated with mole drainage, deep loosening, modeling bands);
- amelioration of saline and alkaline soils by drainage works, deep loosening leveling works, leaching irrigation, etc;
- amelioration of acid and alkaline soils by applying of the amendaments with calcium carbonate and phosphogips;
- researches of the salinity tolerance of cultivated plants (maize, winter-wheat, alpha-alpha, sorghum, Sudan grass, etc.);
- the effect of the different soil management on the chemical and physical proprieties of soils cultivated with Vitis vinifera.
