Samples of saline soil were leached in special lysimeters, then growth with barley (Hordeum vulgare L.) was followed by corn (Zea mays L.). Two sources of potash fertilizer (KCl and K2SO4) were applied in this experiment: 0 (control), 140 kg.k/ha (1 KCl or K2SO4) were applied in this experiment: zero (control), 140 Kg.K/ha (1KCL or 1 K2SO4) and 280 kg (2KCl or 2K2SO4). Plant samples were collected for analysis every three weeks intervals for barley and every two weeks intervals for corn. The results showed that application of potash fertilizer to the reclaimed (leached) soil caused a significant increase in dry matter and potassium uptake of both barley and corn grown successful in this soil
