The sample was dried at 105C in an oven and
the water content was expressed on a fresh weight basis.
The air and soil temperature at a depth of 10 cm were
also measured at the plots. The volume metric soil
moisture in the 0—15 and 15—30 cm layers were monitored
every one to three days by TDR sensors (Moisture
