The reaction is preferably carried out in the presence of an inert porous carrier which is solid at the temperature employed, e.g. CaCO 3 . The calcium nitrate is either sprayed as a solution on to the carrier which is at a temperature between 500 and 600 C. or is mixed with a ...

power, the wetting time, the resistance to acid hydrolysis, and the calcium-ion stability of this series of surfactants were examined, and the results were compared with those of the corresponding sodium alkyl beta-sulfopropionates ROCO(CH2)(2)SO3Na, which have another structure of ester-...
They are responsible for nitrogen fixation in the soil. They change nitrogen into a simpler form such as ammonia, nitrate, and nitrite that can be used by other organisms or plants in the food chain. Detritivores and Scavenger Detritivores ...

Thermal decomposition of gaseous ammonium nitrate at low pressure: kinetic modeling of product formation and heterogeneous decomposition of nitric acid. Since the homogeneous decomposition reaction of HNO(3) itself was found to be too slow to account for the consumption of reactants and the formation...
decomposition of lignin vs. other compounds in litter or SOC. Manganese (Mn) might also protect C by physical or chemical mechanisms18, yet because some forms of Mn are powerful oxidants, increased Mn availability can also stimulate lignin decomposition19. Calcium (Ca) might also have a ...
We used a subset of the global change manipula- tions: two levels of precipitation (ambient and ~ 40% reduction) and two levels of nitrogen (ambient or 60 kg N ha − 1 year − 1 added as slow-release calcium nitrate) applied to subplots within precipitation treatments (Allison et al...
The thermal behavior under isothermal conditions of some ammonia nitrate, ammonia phosphates and calcium phosphates mixtures with added micronutrients was studied. In order to establish the variation of activation energy ( E ) vs. conversion (伪), the TG data were interpolated with spline functions,...
