Topsoil samples derived from a granite parent material were taken from a 9 years old burned forest and incubated at different moisture contents. The soil is bare and its ash bed was already depleted by runoff. A close relationship was found between the factors of soil water content, nitrogen (N) mineralization rate and CO_2 release resulting from the activities of soil microorganisms. The samples incubated at relatively high initial moisture content had a high mineralization rate. After the increase of soil moisture content to 70% of its MWHC (Maximum Water Holding Capacity), the rate of increase was higher in samples with low initial moisture content. In other terms, the dryer the soil samples were, the higher was their N mineralization rate after being moistened at the same final level. The peak recorded in the rate of nitrogen mineralization during the first 3 days after the increase of soil moisture content was followed by a gradual decrease. The increase of soil moisture content had more effect on N mineralization in the case it happened 7 days after the beginning of the incubation than 14 days later. As far as carbon dioxide was concerned, the drier the soil samples were, the higher were their CO_2 release after a sudden accretion of their initial water content adjusted to a final 70% MWHC. Instead of decreasing in the same way N mineralization did, the amount of CO_2 released from soil augmented, suggesting a regain in soil microbial activity which may have led to N immobilization.

The effects of ammonium and nitrate as the nitrogen source on concentration of NO_3^--N, NH_4^+-N, amino acids, protein, carbohydrates and site of nitrogen assimilation were studied in Nerium oleander L. under NaCl salinity. Plants were grown in semi automatic sand culture system in the green house. We distinguished different distribution of carbohydrates and amino acids by nitrogen source under salinity. Ammonium and amino acids concentration increased in roots of ammonium treatment by salinity whereas protein concentration decreased. The level of carbohydrates decreased in leaves and increased in roots by salinity in ammonium treatment. No significant change in level of amino acids and carbohydrates was observed in nitrate treatment due to salt stress. Based on concentration of NO_3^--N, NH_4^+-N in xylem sap, glutamine synthetase and nitrate reductase activity, nitrogen assimilation was mostly done in roots and leaves in ammonium and nitrate treatments respectively. The lower tolerance of ammonium fed plants than nitrate is mostly related to higher diversion of carbohydrates from structure production to roots for ammonium detoxification and osmotic adjustment in ammonium fed plants under salinity.

The effect of ammonium and nitrate as nitrogen source on growth, water relation and ions concentration were studied in Nerium oleander L. under NaCl salinity. Plants were grown in semi automatic sand culture system in the greenhouse. It was revealed that salt tolerance of Nerium plants was significantly increased when supplemented with nitrate as sole nitrogen source than that of ammonium. Total dry weight, leaf area and number were reduced more drastically in ammonium than nitrate treated plants. A higher level of Na^+ and Cl^- was observed in leaves and branches in ammonium treated plants under salinity whereas these ions were accumulated in roots in nitrate. Additionally, salinity induced more decrease in K^+/Na^+ selectivity and K^+ concentration in leaves and branches of ammonium fed plants. Osmotic adjustment was done faster in nitrate treatment and leaves succulence ratio as weight per leaf area did not decrease due to salinity. Decrease in photosynthetic rate was almost similar in both nitrogen treatments under salinity. Our result indicates that nitrate fed plant reduced the level of stress by reducing concentration of Na^+ and Cl^- in leaves. In contrast, sequestration and counterbalance of high concentration of Na^+ and Cl^- in leaves of ammonium fed plants is highly energy required process and diverted the energy from plant production.

The effect of four levels of salinity (0,50,100 and 150mM NaCl) on growth, Na^+ accumulation and nitrogen assimilation in three grasses "Lolium multiflorum, Lolium perenne and Festuca arundinacea" was studied. We report a differential response of Lolium and Festuca species to NaCl salinity where Festuca was found to be more resistant than Lolium species. NaCl induced more reduction in dry weight and photosynthetic rate in Lolium species than F. arundinacea. The Na^+ and Cl^- level in plants increased with the increase in salinity. Shoots of Lolium species accumulated high level of Na^+ and Cl^-. However, high concentration of Na^+ was not observed in shoots of F. arundinacea. Also, the decrease in K^+/Na^+ ratios were more severe in Lolium species than F. arundinacea. The total-N and NO_3^--N concentration decreased drastically in Lolium species due to salinity. However, such an effect was observed only at 150mM NaCl in F. arundinacea. The NH_4^+-N concentration was increased in all species under salinity. The results indicate that Na^+ exclusion probably rescued the Festuca plant from severe stress while in the Lolium species such a resistance mechanism was not established. Our results suggested that there exists potential to utilize Festuca in pasture land management in saline areas.

The vertical movement of soil water and major ions in topsoil of secondary forests were investgated by using D2O and 15NH4Cl as tracers of water and nutrient elements, respectively. Undisturbed soil columns were collected with cylinders made of vinyl chloride pipe in different stands. The rain solution was dropped uniformly on the column by using the artificial rainfall equipment in twice. The artificial rainfall was continued for 10 h at constant intensity of 4 mm/h. At the second time of rainfall, the tracer solution labeled with D2O and 15NH4Cl applied on the column. The concentrations of Cl-, Mg2+, and Ca2+ increased with the D2O discharge and only small quantity of 15NH4+-N moved to the lower horizon on the Brown forest soil columns. The downward velocity of the D2O-tagged water agreed approximately with that of Mg2+ and Ca2+. But large amount of the 15NH4+-N was discharged with the D20-tagged water on the column that was collected in the forest floor removal stand. In spit of heavy water discharging, the concentration of Cl- in discharged soil solution did not increase obviously in Andosol column because of the effect of anion absorption into the soil.
