Abstract


Soil (ground) is for people amid social and economic activities, natural resource invaluable, the most precious wealth of a nation. From this point of view, Romania has a great wealth, especially given balanced structure planning: third area of forests, meadows third of hills, orchards and vineyards and third lowland land where farming takes place. We live in an excessive continental climate area, prolonged droughts and growth in the last 10 years, annual average temperatures 0.2 to 0.6 ° C and decreasing precipitation with 10 to 15 mm, to multi-annual averages, due current decrease geosystem reveals a clear tendency to increasing and expanding desertification phenomena and land degradation especially in the south and east of the country, however the necessary impetuous clear evidence nationally, regionally for different areas (hilly area of lowland, mountain) land situation in Romania. Preventing soil erosion requires measures imposed by climatic characteristics of the area and socio-economic status, medium and long term actions to improve the situation of soil, which can then be combined nationwide to save and to ensure rational use and exploitation and sustainable land it holds Romania, regardless of land ownership.
