Abstract

Nutrient losses due to brick production were evaluated at 50 Upazilas in nine districts of the central region of Bangladesh. The average land area occupied by a brick kiln was 0.59 ha. Water‐ extractable N, P, K and S, and total N, P, K and S decreased by 67, 60, 62, 53, 67, 67, 87 and 33% in burnt bricks compared to unburnt one, respectively. Permanent loss of huge quantity of plant nutrients is occurring due to brick manufacturing every year in Bangladesh.
