A dire consequence of the elevation levels to which water has to be pumped is
the high energy costs involved in the process:
Low levels:
0–700 kWh/ha...
10% of the land
Medium:
700–1400 kWh/ha... 28.6% of the land
Medium–High: 1400–2100 kWh/ha... 48.2% of the land
High:
over 2100 kWh/ha... 13.2% of the land
During the exploitation phase of the irrigation systems in Romania, the share of
the areas where the applications were administered reduced gradually, which is one
of the causes wherefore the projected yields were not achieved (see Fig. 41.6).
Moreover, the inadequate watering equipment quality also caused water losses and
puddles (water stagnation) during the applications (Fig. 41.7).
