THE INFLUENCE OF AN INDUSTRIAL SLAG ON THE MACROELEMENTS CONTENT IN THE SOIL
To maintain the quality of the soil it is required its use according the characteristicsÂ it has. This implies the inclusion on the appropriate use of any kind of waste, nutrients andÂ pesticides management; improve physical and chemical characteristics, to avoid pollution.Â The ability of steel slag to improve the characteristics of acidic soils may be explained byÂ the high content of calcium and magnesium. The paper describes the changes thatÂ occurred with regard to existing macroelements in soil as a result of using different dosesÂ of steel slag (0%; 0.1%; 0.2%; 0.3%; 0.4%; 0.5%) for the purpose of amending the soil.
Macroelements such as nitrogen, phosphorus and potassium, as well as organic carbonÂ content are presented. Changes in the total nitrogen content and soluble potassiumÂ content were strongly influenced as a result of treatment.
