      abstract     = {Plastic film mulching has commonly been used for adaptation
                      to water scarcity and for increasing agricultural
                      productivity on the semiarid Loess Plateau of China.
                      However, the effect of plastic film mulching on cropland
                      soil water and thermal regimes on the semiarid Loess Plateau
                      of China is not well understood. This study simultaneously
                      monitored the dynamics of the soil water content and the
                      soil temperature with high resolution in a ridge cultivation
                      system with plastic film mulching (RS) and a flat
                      cultivation system without plastic film mulching (FS) during
                      the maize (Zea mays L.)-growing season. We found that, in
                      general, the soil temperature and soil water content were
                      significantly different among the ridge under RS (RS-ridge),
                      the furrow under RS (RS-furrow) and FS throughout the
                      maize-growing season (P < 0.05). Plastic film mulching
                      increased the near-surface soil temperature by approximately
                      1°C throughout the study period. RS significantly increased
                      the soil water content during the dry period (May to June),
                      especially within the middle soil layer (30–60 cm),
                      compared to FS. The lowest monthly average soil water
                      content was found at a depth of 30–60 cm layer in FS
                      during the dry period (May and June). The water depletion
                      was found within deeper (100–160 cm) soil layers in May
                      but the water storage in the same layer of FS in June
                      increased although it was the dry period, which differed
                      from RS. The RS practices showed a longer period of water
                      supply from the deeper soil layer (100–160 cm) in May and
                      June for meeting maize water demands during the early
                      growing stage rather than in only May for FS. During June
                      (dry period), the water storage at a depth of 0–60 cm was
                      greater in RS than in FS, and the reverse was true at a
                      depth of 60–160 cm. The results indicate that the dry soil
                      layer at a depth of 30–60 cm formed during June in FS
                      likely reduced water movement from deeper layers to the
                      topsoil layer, and hence constrained the availability of
                      surface soil water for meeting maize water requirements
                      during the early growing stage (dry period). Our study
                      suggests that RS tends to significantly increase surface
                      soil water availability by restraining the formation of a
                      dry soil layer during the early maize-growth stage primarily
                      under dry conditions, and thus enhances maize productivity
                      in the semiarid Loess Plateau of China.},
