abstract = "The processes of water transfer in the soil-plant-atmosphere
system are strongly affected by soil use and management.
Differences in the dynamics of soil water transfer between
no-tillage (NT) and conventional tillage (CT) practices during a
soybean (Glycine max) growing season in southern Brazil were
assessed in this study. All the water balance components were
analyzed during the soybean growing season (2009/2010). Rainfall,
runoff, soil water storage and hydro-physical soil properties were
analyzed under two tillage systems. The land-atmosphere water
vapor exchanges, obtained from eddy covariance stations, were
analyzed with regard to the soybean agroecosystem.
Characterizations of soil water storage were also formulated in
the 2006/2007 and 2008/2009 soybean growing seasons under the NT
system. During the periods without rain, the soil water content
under NT was greater than under CT. The soil superficial layer,
more porous under NT, contributed to less runoff during rainy
events. Moreover, under NT conditions the water supply was always
high, between 0.2 - 0.5 m. The total evapotranspiration in the
soybean agroecosystem growing season was 410.8 mm.",
