1985
Huthily, K.H.
The effect of different levels of salinity in two soils of different textural closses silty clay and sandy loam on microbial activity (Carbon dioxide evolution), N minerilization, nitrification and ammonia volatilization, was studied. The study showed that there is a significant, negative correlation (P0.01) between the increasing of salinity levels and period of germination, plants height, dry matter weight, total leaves area and total N content in shoots. The statistical analysis showed that there were no significant differences in amount of (NO2+NO3) that developes in soils at salinity levels (5.0, and 7.1 mmhos/cm) as well as at the levels (12.1, 17.8, 24.0 and 30.0 mmhos/cm)
