Instrumental analyses with Fourier transform infrared (FT-IR) spectroscopy, 13C-nuclear magnetic resonance (13C-NMR) spectroscopy and 1H-nuclear magnetic resonance (1H-NMR) spectroscopy indicated that FA1 and FA2 shared common functional groups existed in typical fulvic acid. A series of rice seed ...
The infrared (IR) spectral data showed a decrease in the intensity of COO group bands (1623 and 1399.5 cm1); this is correlated with a decrease of fulvic acid levels. The variations observed in NMR spectra could be explained by the involvement of COO groups of certain structures in poly...
Fulvic acid-like substancesPeanut sproutSelenite tolerance and selenium accumulationThe results showed that with 15mg路L 1 Na 2 SeO 3 , PFA significantly increased both the total and hypocotyl fresh weight of the seedlings but reduced the fresh weight of the root. PFA also effectively promoted ...
mushroom bed wasteextractionplant growthA huge amount of mushroom bed waste(BW)is generated in Japan.For the purpose of effectively utilizing the BW,we report on extraction of fulvic-acid-like compounds(FALC)from the BW according to the IHSS method.Characteristic spectral shapes from ultraviolet-...

fulvic acidmanure3EEMsThe organic reserves of native soils strongly decrease with cultivation. On the other hand, animal waste and sluge in the form of manure are largely recycled to agricultural lands as the most economical and enviromental issues related to treatment and reuse. These materials ...

In this work, we demonstrate that amino acid- and ammonium sulfate-catalyzed reactions in water and ionic solutions produce compounds of identical molecular and optical properties and account well for the quantities found in atmospheric particles. For typical aerosol concentrations of amino acids or ...
