​Cotton production in the US Southern Great Plains continues to expand to the north each year. New cotton growers in this region have expressed great interest in gaining a greater understanding of fiber quality and how it can be influenced by post-production processes. This presentation discusses the influence of harvest and ginning practices on fiber quality and identifies critical points for producers to consider in efforts to maximize fiber quality and economic returns. Moreover, lint bale contamination from plastic module wrap is estimated to cost US producers about $500 million annually. This presentation discusses new technologies and module handling practices that help to mitigate the issue of plastic contamination in the field and during the ginning process.
