Gas-to-liquid (GTL) sludge is a specific wastewater treatment by-product generated during the industrial process of natural gas conversion into liquid fuels. This least studied sludge is pathogen?free and rich in organic matter and plant nutrients. Therefore, it can be recycled in agricultural soils as an organic amendment and reduce therefore the potential risks of landfilling. In this open field study, we compared the performance of soil treatments with GTL sludge to the more conventional chemical fertilizers and cow manure compost for the cultivation of cotton under the natural conditions of Qatar. After a complete growing season, GTL sludge application resulted in the enhancement of soil properties and plant growth compared to conventional inputs. As such, there was a significant dose-dependent increase of soil organic matter (4.01% and 4.54%), phosphorus (534 and 1090 mg kg-1 ), and cumulative fiber yield (4.68 and 5.67 t ha-1 ) for GTL sludge application rates of 1.5% and 3%, respectively. The produced ...
