Popis:	Earth’s total land surface equals 13.2 × 109 ha, of which no more than 7 × 109 ha is arable and only 1.5 × 109 is cultivated (Massoud 1981). Of the cultivated lands, about 0.34 × 109 ha (23%) is saline and another 0.56 × 109 ha (37%) is sodic. Fig. 1 (Szabolcs 1989) shows that saline and sodic soils cover about 10% of total arable land distributed over 100 countries. Although natural factors are the main causes of the occurrence of saline/sodic soils, also man induced salinity and sodicity problems occur in large areas as a consequence of improper irrigation drainage design and management.
