Application of BOF Steelmaking Slag as a Partial Replacement of Agricultural Fertilizer
The iron and steel industry generates wastes of varying types while processing ore to produce steel through sequential processing steps. Steel slag is a major waste, and its accumulated generation is increasing with time, even though the rate of generation of slag per unit of finished steel produced is declining. Over the years, various methods such as land fill, cement, road making, etc. have been employed to handle slag, and some of these slags can also be utilized successfully in agricultural applications as acidity regulators. The present work aims for an effective utilization of steel slag to enhance crop productivity and turn it into a high value-added product for sustainable cultivation. Along with basic oxides, steel slag also contains some essential nutrients for plants, such as silicon, phosphorus, etc. Steel slag partially helps as fertilizer for the growth of plants without harming the environment, thus helping manage steel industry waste for sustainable development and contributing to both the economy and the environment. Replacement of commercial fertilizer with steel slag will help abate its disposal problem as well as increase profitability for the farmer. In this study, the effects of steel slag on the growth of pea and chickpea plants were studied quantitatively. A study was conducted to evaluate the optimum conditions for the utilization of steel slag as fertilizer. Initially, commercial fertilizer was partially replaced (20–60%) with steel slag applied to soils in three districts in West Bengal, namely Purulia, Bankura, and Paschim Bardhaman. Later, in a separate set of experiments, commercial fertilizer was also partially replaced (70–90%) with steel slag applied to soils from Paschim Bardhaman district. The linear growth of the plants was monitored on a daily basis. Optimized process parameters have been calculated based on experimental results collected over 2 months. The positive impact of the use of steel slag on plant growth may thus open up a sustainable alternative to commercial fertilizers for agricultural practice.
