The mean maximum hourly soil temperature ranges at 15 and 30 cm in the PMV plots were 32.1–49.4 °C and 31.8–45.3 °C, whereas for the untreated control plots they were 29.8–43.2 °C and 29.3–41.7 °C, respectively. At 15 cm, temperatures in the SS plots ranged from 34.2 to 51.3 °C, and records at 30 cm were not available. At 15 cm, the increases in maximum hourly temperature in the PMV and SS plots relative to the untreated control plots were 6.2 °C and 8.1 °C, respectively. However, at 30 cm, the increase in the maximum hourly temperature in the PMV plots over the untreated controls was 3.6 °C.
