Implications of undersowing in the context of mulch removal.
Loose materials like straw, bark and composted municipal green waste can provide effective weed control, but the depth of mulch needed to suppress weed emergence is likely to make transpos e cost prohibitive unless the material is produced on the farm (Merwin et al., 1995)… Increasing of the quantity of mulch applied increases the effects on soil moisture and temperature (Scott, 1921; Russel, 1940); therefore, large application rat es (10 t/ha and more), which were common in past studies and practice appear to increase the risk of yield reduction in cooler climates…
"Pest" Control, Mulch, Potatoes
In 2001, there were no differences in numbers of colonizing potato leafhopper or Colorado potato beetle adults, but by midsummer there were more Colorado potato beetle larvae in the control plots than in the straw plots, again possibly due to differential predation.
Using the weed barrier will kill a flush of new weed growth or a thick stand of 1-3 ft tall grass or broadleaf weeds. The weed barrier does not have to sit very long, just 1-2 weeks (1 wk if dry and 2 wks if wet) to create a ‘stale’ seed bed under the mulch or on the bare ground. It can then be moved to another location in the field for weed control.
