In order to solve and clarifying certain aspects of the clay content (particles [0.002 mm) sands and sandy soils, humus, respectively, the process of bioaccumulation and mineralization the organic matter of the land, in the Research and Development Centre for Plant Growing on Sand Dabuleni, have initiated research aimed at finding methods and means for accumulating and thus the increase in the content of clay in the soil, respectively humus.Therefore, to improve radical of sandy soils, we found it necessary to resort to what is called loess process. It consists in enriching the horizon the surface soil (20-25 cm) the fraction with 8-10% clay, to 1.5-5%, as currently it contains. It is primarily intended to influence various amounts loess material on physical, hydro- physical and chemical properties of soils, then the plant response to changes products in the soil, increasing the guaranteed potential fertility of these soils, which will result in production high and constant.Obtaining appropriate agricultural production on sandy soils (eutric psamosol) it is limited not only by the soil, but also other factors such as relief, drainage and even climate. Because coarse texture, water-holding capacity in the case of sandy soils it is very low in all soils, the clay content below 5% production capacity of soils it is particularly low in the absence of agropedoameliorative measures and especially irrigation. Wind erosion occurs in all perimeters sandy soils, with higher intensity is observed in Oltenia Plain (Dabuleni Field).

The territory to which we refer is located in the geographical area of the Romanian Plain, north-eastern sector, representing a subunit of Plain Covurlui. From the administrative point of view this territory belongs entirely Galaţi County. Since the first review of Cuca Plain territory fragmentation is found in the form of ridges interfluvial oriented northwest-southeast separated by a river system consistent. The provision gives relief peaks ordely character of monotony. Starting from the idea that the soil appears as a product of the interaction of many factors, we can say that the formation of soil cover of Cuca Plain took part relief, parent material, climate, groundwater, vegetation, human activity. Under the influence of environmental factors and pedogenetic processes in the Cuca Plain were differentiated two classes of soils, namely: protisols and cernisols.
