NICKEL DISPERSION IN SOIL AND ITS EFFECTS ON AGRICULTURAL CULTURE IN ELBASANI TOWN, ALBANIA

Through this scientific work we have tried to provide data on the quantitative presence of heavy metals in the soil composition for the Elbasani region. The presence of heavy metals especially when they appear above the allowed limit cause soil pollution and inevitably affects the cultivars that grow on it. To identify their presence, we have analyzed soil samples belonging to the Elbasan area, one of the cities with the highest agricultural models productivity in the country but also the most polluted as a result of industrialization.

The purpose of this scientific paper is to identify the link that exists between chemical pollution of soil and agricultural crops grown on soils located at Elbasani. For the realization of this goal soil samples were taken during the month of October-November 2020.

We emphasize the fact of selection as a study area that of Elbasan, as recently has been the subject of study of many authors precisely for the reason of labeling an area with considerable pollution of air, water and soil, mainly of bacteriological but also chemical nature. We think that this phenomenon is dedicated to the abusive activity to the detriment of nature of the heavy industries operating in this town as well as the indiscriminate use of chemical and organic fertilizers by farmers.

Soil samples weighing about 1 kg were taken by drilling with a rotary probe to a depth of 15-25 cm. After sampling they are stored in sterile plastic containers until further processing in the laboratory using the FAAS method.

Based on the results obtained from data processing we consist of a presence of chemical soil pollution caused mainly by the Nickel (Ni) which is presented at levels about four times higher than the standard values set by the Albanian State but also the EU Regulation.
