University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers are continuing their studies in paper mulch with respect to watermelon production in the Southeast. Its development is important for a region that depends heavily on watermelon production.
Bob Hochmuth, University of Florida Institute of Food and Agricultural Sciences Regional Specialized Extension agent in Live Oak, Florida, discussed paper mulch at this year’s Suwanee Valley Watermelon Institute. He noted the project is still in the research and development stage.
“We do plan to have limited opportunities this upcoming year, maybe four or five farms on just an acre or two to continue to develop it from a research standpoint,” Hochmuth said. “There’s still some research that they’re doing on the combination of the codings and the paper.
“It’s an expensive product and we’re trying to get to the point where we can look at different ways that they’re making the product and make it a little bit more affordable.”
The WestRock product may be pricey, but it offers multiple benefits for growers; most notably its ability to provide nutsedge control.
“Nutsedge suppression is the clear advantage. Nutsedge just will not come through the paper, and then you have the other attributes where at the end of the season, you can till the product in,” Hochmuth said. “Some landowners do not like the farmers to use plastic of any kind, so that helps us in that regard.”
Paper mulch does not degrade as quickly over time, and it is easier and quicker to apply before the season.
