Soil
acidity greatly restricts crop yields in red and lateritic soils common in
tropical areas, such as India. Traditional liming materials are usually too
costly or not suitable for use under such conditions. Basic slag, an industrial
waste from the steel industry, is a potential solution as it is highly rich in
neutralising value and releases essential nutrients such as calcium, magnesium,
silicon, and phosphorus slowly. This chapter assesses the advantages of basic
slag in agriculture, especially in improving soil acidity and boosting crop
yields. Long-term experiments suggest that it increases the soil pH, lowers
toxic aluminium contents, and increases the crop yield by supplying silicon in
bioavailable form that assists in stress endurance and nutrient uptake. It also
treats environmental sustainability in circular economy perspectives, and the
risks associated with it include heavy metal contamination and logistics,
policy, and farmer knowledge issues. In general, basic slag is discovered to be
a low-cost, environmentally friendly amendment that can restore marginal soils
and assist in environmental sustainability objectives.
