Denim Sludge as a Soil Amendment: Effects on Cotton Growth Parameters

D.O. Porter, R.P. Porter


Cotton garment finishing operations, which involve garment washing and drying, generate appreciable quantities of cellulosic wash solids. As a part of ongoing research to investigate waste disposal options for a major garment manufacturer, bench scale tests were conducted to determine if land application is a feasible option for wash solids utilization. Observations indicated that soil moisture retention, soil aggregation, and permeability were improved by the addition of wash solids. Plant emergence, growth, and fruiting were improved by low and moderate applications of wash solids, but were not improved by heavy application of wash solids.
