Comparison of inductively coupled plasma mass spectrometry and colorimetric determination of total and extractable phosphorus in soils

Multi-element characterization of archaeological floors at the prehistoric archaeological sites at Ban Non Wat and Nong Hua Raet in Northeast Thailand

“…Chemical element analysis using ICP-MS has many advantages, especially allowing the simultaneous determination of broad range of element identification in geoarchaeological studies (Entwistle and Abrahams, 1997;Ivanov et al, 2012). The drawback of spectrometry techniques is that they first require the solid sample to be transformed into solution (Sastre et al, 2002).…”

Effect of the Fertilizer Application Method on Soil Abundance in Available Sulfur

“…The soil pH was determined by potentiometry in 1 mol·dm -3 KCl suspension, whereas available sulfur was extracted with 0.03 mol·dm -3 acetic acid (10:1 (v:m), 30 min, 40 RPM) (Ostrowska et al, 1991). Available phosphorus was determined by Egner-Riehm method (Ivanov et al, 2012), after extraction with calcium lactate at pH 3.55 (5:1 (v:m), 90 min, 40 RPM). The sulfur and phosphorus content in the solutions was determined using inductively coupled plasma optical emission spectrometry (ICP-OES), using a Perkin Elmer Optima 7300 DV spectrometer.…”

Effect of organic and mineral fertilizers on soil P and C levels, crop yield and P leaching in a long term trial on a silt loam soil

“…These parameters estimate the labile C and P fraction of the soil. To measure the total P content of the soil, the method of Ivanov et al (2012) for a microwave digestion method was used as follows: 0.5000 g of oven-dry soil (70 C, <250 mm) was destructed for 30 min at 200 C in 12 ml aqua regia in a microwave oven. After filtration on a Whatman 640 d filter, the P concentration of the filtrate was measured with ICP-OES.…”
