THE INFLUENCE OF AN INDUSTRIAL SLAG ON THE MACROELEMENTS CONTENT IN THE SOIL
Abstract
To maintain the quality of the soil it is required its use according the characteristics it has. This implies the inclusion on the appropriate use of any kind of waste, nutrients and pesticides management; improve physical and chemical characteristics, to avoid pollution. The ability of steel slag to improve the characteristics of acidic soils may be explained by the high content of calcium and magnesium. The paper describes the changes that occurred with regard to existing macroelements in soil as a result of using different doses 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 carbon content are presented. Changes in the total nitrogen content and soluble potassium content were strongly influenced as a result of treatment.
