Paper mulch continues to show adequate evidence in North Florida watermelon research that it provides strong nutsedge control.
Bob Hochmuth, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Regional Specialized Extension agent in Live Oak, Florida, discussed this year’s research with the WestRock product.
“We’re very excited about the potential in the future. There’s no question that if a farmer has a field with heavy nutsedge that they’re going to be going in to, even though it’s likely to be more expensive, it seems to be a real easy decision to consider using paper mulch in that particular instance,” Hochmuth said.
“If the field does not have heavy nutsedge, there probably are some other advantages; not having to pull the plastic up out of the field and being able to disc in the paper is an advantage. We’re still working on some of the research trials about whether or not the paper mulch retains heat and moisture, especially early in the season. We’re continuing to do that research.”
Another benefit of paper mulch is that it does not degrade as quickly over time, and it is easier and quicker to apply before the season.
The costs associated with paper mulch are expected to be higher, however. It has to be coated to reduce degradation and painted black to get the warming benefits.
“I’m still very excited about it. It’s a very high-quality product that can withstand the rigors of our machinery. I’m very excited about the potential future there and see whether or not it becomes commercialized in the upcoming year,” Hochmuth said.
