Effect of salinity on N mineralization in artemia pond
Soil samples taken from artemia ponds were air-dried, crushed, sieved and submerged with salinity at rates of 35, 50, 65 and 80ppt. High salinity decreased net N mineralization rates as well as accumulated N contents at the beginning of incubation (at 80 ppt, mineralized N reach only 74-92% of 35 ppt). At the end of incubation, rates of N mineralization in some soils were increased and reestablished in despite of high salinity.
