Journal ArticleDOI
Evaluation of a soil incubation method to characterize nitrogen release patterns of slow- and controlled-release fertilizers.
TL;DR: The soil incubation technique was demonstrated to be robust and reliable for characterizing N release patterns from SRFs and CRFs, and variations in soil/sand ratio, temperature, and soil had little effect on the results.
Journal ArticleDOI
Determination of arsenic, cadmium, cobalt, chromium, lead, molybdenum, nickel, and selenium in fertilizers by microwave digestion and inductively coupled plasma-optical emission spectrometry detection: collaborative study.
Peter F Kane,William L Hall +1 more
TL;DR: A method has been developed using microwave digestion with nitric acid at 200 degrees C, followed by inductively coupled plasma-optical emission spectrometry instrument detection, for the elements arsenic, cadmium, cobalt, chromium, molybdenum, nickel, lead, and selenium, and it is recommended for AOAC Official First Action status.
Journal ArticleDOI
Evaluation of commonly used methods for the analysis of acid-soluble phosphate in internationally traded inorganic fertilizers.
William L Hall,Sanford A Siegel +1 more
TL;DR: A method comparison process and statistical evaluation of analysis of total phosphate content in concentrated phosphate fertilizers found four methods to be acceptable as best practice methods.
Journal ArticleDOI
Optimization and validation of an accelerated laboratory extraction method to estimate nitrogen release patterns of slow- and controlled-release fertilizers.
TL;DR: Ruggedness of the method showed ruggedness for measuring N release rates of coated CRFs, with a highly marked effect for phosphorus and to a lesser extent for nitrogen (N) and potassium.
