摘要：

Determination of the water supply available in soils for crops is important for a calculation of the water balance, and the prediction of water shortages. Available water content, at several Czech Republic localities at the start of growth, were calculated with simple pedotransfer functions from the texture of soil layers, and compared to water contents to a depth of 130 cm, determined experimentally. Available water content in the root zone of selected crops was calculated from data on root density distribution and from the estimation of water depletion distribution.
