However, gypsum application resulted in an increase of AlSO 4 + activity and in a decrease of Al 3+ activity. Relative maize and groundnut yields were negatively correlated with Al 3+, Al(OH) 2+ and Al sum activities. Likewise, relative yields were negatively correlated with Al concentration and the Al concentration ratio and positively correlated with soil solution Mg concentration and Ca/Al ratio.

Technology

It is a ternary blend of clinker, calcined clay, crushed limestone and gypsum. A nominal blend uses 50% clinker, 15% non-cement grade limestone (high silica or high MgO content), 30% calcined clay (non-ceramic grade) and 5% gypsum. Calcined clay is calcined between 700-800°C and ground with clinker, gypsum and raw limestone.
