THE CROPPING CHARACTERIZATION OF SOILS FROM VLADAIA LOCALITY, DISTRICT MEHEDINTI
The cropping characterization of soils is an operation of research for evaluating the fertility and suitability of soils for different crops and establishing the measures for their improving. In this respect, after field research and laboratory analyses there was identified as soil type the reddish preluvisoil with the following divisions: typical, middle eroded, luvic and, on small scale, aluvisoils with colluvic and gleysated divisions.
The laboratory analyses have emphasized an average and reduced fertility of these soils which can be improved through rational fertilization measures including fertilizers and manure, by special soil management practices for slope terrains, by amendment application, deep tillages and removing stagnant water. The choosing of the most appropriate crops are a measure of improving these soils and that is why by bonitation there was established the suitability of several crops and ways of using of these soils. This way, on the typical preluvisoil the choose of crops include cereals and orchards due to their good results, while on eroded preluvisoil the most appropriate crop is vine, orchards (apricot tree) and pastures; these crops have obtained the highest bonitation marks (72, 65 and 46). The reddish luvic preluvisoil offers good conditions for pastures (64 points), wheat and barley (58 points) while on alluvisoil and colluvic glaysated alluvisoil the highest bonitation marks and growing conditions have been given by sugarbeet (63 points), hayfields (63 points) and pastures (64 points).
