The Temperature Dependence of the Isotope Effect for Electromigration of Potassium Ions in Molten Potassium Nitrate
generally interpreted as an indication of "complex ions" (which is another way of saying that a simple model with only three ionic species is inadequate) . The small absolute value of r12 in the A g N 0 3 — K N 0 3 mixture makes the experimental uncertainty more important. Thus the positive value at 380 °C indicates that also the value at 340 °C should be (small and) positive (since increased t...
متن کاملEvaluation of low temperature tolerance indices in seedlings of Citrus aurantium under potassium nitrate nutrition.
In order to evaluate the effects of potassium nitrate nutrition on some low temperature tolerance indices in Citrus aurantium seedlings a factorial experiment was conducted based on a completely randomized design with four replications at the Institute of Citrus Research in Ramsar. Treatments were potassium nitrate nutrition at four levels (0, 2.5, 5, and 10 mM) and temperature at four levels (...
متن کاملThe Temperature Dependence of the Isotope Effect for Electromigration of Lithium Ions in Molten Lithium Nitrate
where t is the temperature in °C and the quoted error is the standard deviation. There is thus in this case no significant influence of the temperature upon the mass effect. Some previous investiga tions of molten LiN03 gave smaller values for the mass effect. The reasons for these apparent dis crepancies are discussed. A slight, but significant, anomalous enrichment of the light isotope is o...
متن کاملSalt Tolerance in Rice Cultivars and Changes in Sodium and Potassium Ions
Salinity is an environmental stress that limits growth and development in plants. Due to high salinity in Khuzestan soils it is necessary to identify cultivars with appropriate yield that are compatible with Khuzestan conditions. This experiment was done to evaluate three rice cultivars for salinity tolerance at seedling stage by measuring the absorption of sodium and potassium ions and the rat...
متن کاملLong-term tillage and residue management effect on soil compaction and nitrate leaching in a Typic Haploxerert soil
A field experiment was conducted to compare the effects of long-term tillage and cropresidue management on some physical properties and nitrate leaching of a Typic Haploxerertsoil under winter wheat (Triticum vulgare L.)-soybean (Glycine max L.) double-croppingsystem. The tillage systems consisted of conventional tillage with stubble (CT1), conventionaltillage with stubbles burned (CT2), heavy ...
