These resources detail the process and findings from an applied research project that studied the effects of nine commercially available plastic films as mulches and as crop protection.
The two-year project studied:
- Using plastic mulches to impact soil temperature and surface energy balance
- Using plastic films in low tunnels to modify microclimates and enhance plant growth
Some of the project findings included:
- Black and clear plastic mulches can increase soil temperature near the soil surface by ~40%
- High reflectivity plastic mulches can cool soils by ~20%
Details about yield results in low tunnels are also included in the full report. A video provides an overview of the project.
