Quantification of Ammonium Sulphate Nitrate (ASN) fertilizers
This paper shows a simple procedure for the quantification of industrial and laboratory samples of Ammonium Sulphate-Nitrate fertilizers (ASN) based on a Rietveld fit from X-ray powder diffraction profiles. The Rietveld fit is performed by means of the structural models of the double salts 2NH4NO3·(NH4)2SO4 and 3NH4NO3·(NH4)2SO4, previously reported by the authors. The proposed method demonstra...
متن کاملNeutral Ammonium Citrate Extraction of Biosolids Phosphorus
Matching biosolids application rates to crop phosphorus (P) needs requires quantifying the P fertilizer replacement value of biosolids. Neutral ammonium citrate (NAC) extraction of P, used for assessing available P in mineral fertilizers, was evaluated for 35 different biosolids. Biosolids NAC-P was not statistically different (p 1⁄4 0.05) from total P using strong acid digestion (EPA 3051-P). ...
متن کاملSynthesis and characterization of ammonium phosphate fertilizers with boron
The concentration of boron, an essential micronutrient for plants, presents a narrow range between deficiency and toxicity. In order to provide the boron requirement for plants, and to avoid toxicity problems, boron compounds are mixed with basic fertilizers. Sodium borate pentahydrate was used as a boron source. Ammonium orthophosphates fertilizers with boron were prepared by neutralizing phos...
متن کاملMycobacteria with a growth requirement for ferric ammonium citrate, identified as Mycobacterium haemophilum.
Three previously unidentified strains of pathogenic mycobacteria which had been isolated on media containing ferric ammonium citrate were found to be identical with the new species, Mycobacterium haemophilum.
متن کاملN-sulfonic acid pyridinium-4-carboxylic acid chloride as a novel and efficient catalyst for the condensation reaction of aldehyde with thiobarbituric acid and ammonium acetate
N-sulfonic acid pyridinium -4-carboxylic acid chloride {[Pyridine-N-SO3H-4-COOH]Cl} was synthesized, identified and applied as an effective catalyst for the preparation of pyrido[2,3-d:6,5-d]dipyrimidines by the condensation reaction of various aldehyde with 2-thiobarbituric acid and ammonium acetate under solvent-free conditions.The structure ofcatalyst was studied...
