Soil degradation, which is linked to poor nutrient management, remains a major constraint to sustained crop production in smallholder urban agriculture (UA) in sub-Saharan Africa (SSA). While organic nutrient resources are often used in UA to complem... Read More about Waste to resource: use of water treatment residual for increased maize productivity and micronutrient content.

Journal Article
Stone, W., Lukashe, N. S., Blake, L. I., Gwandu, T., Hardie, A. G., Quinton, J., …Clarke, C. E. (2021). The microbiology of rebuilding soils with water treatment residual co‐amendments: Risks and benefits. Journal of Environmental Quality, 50(6), 1381-1394. https://doi.org/10.1002/jeq2.20286

Water treatment residuals (WTR) are sludges from the potable water treatment process, currently largely destined for landfill. This waste can be diverted to rebuild degraded soils, aligning with the UN's Sustainable Development Goals 12 (Consumption...
