In the current research, the effects of some organic fertilizers as fulvic and humic acids on the vegetative growth of pistachio seedlings in a semi-hydroponic culture containing Fe-EDDHA (as a synthetic fertilizer) and FeSO4 (as an inorganic fertilizer) were investigated. The alkalinity is recognized as a main problem in pistachio orchards, therefore the pH of nutrient solution was ...

Humic substances are defined as the result of decomposition any organic matter, and they consist mainly humin, humic, fulvic acids. Compared to humic acids acid (FA) most explored compounds. However, FAs less studied than because usually small residual quantities. Considering that its potential for bioactivity is stronger acids, current review was performed evaluate effectiveness FA application...

Europium speciation is investigated by time-resolved luminescence spectroscopy (TRLS) in the presence of Suwannee River fulvic acid (SRFA). From complexation isotherms built at different total Eu(III) concentrations, pH values, ionic strength, and SRFA concentrations, it appears that two luminescence behaviors of Eu(III) are occurring. The first part, at the lowest CSRFA values, is showing the ...
