Ascertained: Similarity indices for soil water regimes according to the laws of similarity of physical systems based on the hydraulic model operational experience. Water supply index of farming soils characterizes boundary (regional) conditions and is applied for foundation of the requirement of using water conservation. The indices of soil water capacity, internal soil water exchange and surface flow are characterized as local factors of making up water balance and may be used at foundation of the required relationships of reclamation and humidification (irrigation) land developments. Depending on the task to be accomplished each local factor may serve as for evaluation of initial conditions, or to be presented as an index of dynamic similarity. The evaluation and comparison indices of soil water regimes of root-inhabited soil layer is recommended to be used for research-founded adaptation of experimental results obtained in the process of model (stationary) experiments to natural (operating) conditions of water balance control, as well for evaluation of water relationships of reclaimed soils that considerably change their water-physical properties in the process of long-term farming exploitation.

Ascertained: Interconnection of willow crop to levels of ground waters. It is also proved that at igh level of ground waters willow uses more water than traditional field crops during their vegetation period. The efficiency index of water use (WUE) reflecting the ratio of plant mass yield to quantity of water used has the most favorable value in light soils at a depth of ground waters equal to 100 cm. The results of investigations show that growing willow for the purposes of energy requires large quantity of water, in what connection shortage of water considerably restricts crop-producing power of willow plantations. Taking into consideration the restricted water resources of Poland the expansion of willow production to industrial scale may result in increase of water deficiency.
