Polyethylene mulch, glazing create optimal conditions for soil solarization

Researchers raised soil temperatures in high tunnels in southern Arizona to determine the efficacy of soil solarization using clear mulch on the soil surface and with tunnel glazing or with no glazing. Outcomes showed that producers using high tunnels in the region can complete solarization in less than a week during summer when the soil is fallow using glazing on the high tunnel and polyethylene mulch on the soil surface.
