Abstract:
The sustainable development of the rural area from Romania requires 
a balance between the economic increase and the environment protection, 
according to soil quality and to strategy of the means of using land 
resources. The soil-climatic conditions from Baia Depression – the 
hydrographical basin from the extra-Carpathian area of the Moldova River - 
have frequently determined the presence, under different forms, intensities 
and periods, of temporary water excess from soil. The underground 
drainage, as a measure of water excess control, with stagnant character, 
caused mainly by rainfall amounts registered for 1-5 consecutive days, was 
firstly arranged in pilot-experimental fields during 1972-1978. We followed 
the behaviour in exploitation of underground drainage technical solutions, as 
concerns the functional efficiency  of the means of water excess removal and 
of the improved soil favourableness and/or suitability for crop growing.  
In order to assess the long-term effects of ameliorating works, applied 
in 1978 in the drainage field of Baia, on an area of 3.50 ha, we have 
qualitatively classified and estimated the albic stagnic glossic Luvosoil 
(S.R.T.S. – 2003),   improved and unimproved. Based on this study, we have 
estimated the present favourableness for crops of the improved soil, as 
compared to unimproved soil, used as natural grassland, after an 
exploitation cycle of 30 years (1978- 2008).
