Studies upon the quality status of a terrain occupied by a sugar manufacturing waste deposit

Abstract

The paper presents the established studies in order to determine the quality and reliability of the soils for agriculture purpose from the “decantation lake” belonging to a Romanian sugar industry. Towards these it were made 3 soil profiles and it were assayed 3 soil samples from each profile in order to determine the physic-chemical characteristics. Each profile was investigated “in situ” through specific pedological methods being identified two soil classes and two types of soil. It were also determined the bonity notes and the soil fertility showed by the trophicity index. The obtained results indicated the analyzed soils have a low trophicity index that means that they are into oligotrophic and extremely oligotrophic classes. The area is into the 5th class of pretability that comprise terrains with very severe limitations, unpretable for agriculture purpose in terrain undevelopment conditions and for valorification there are necessary the application of agropedireliability works.
