Phosphorus exchangeability and leaching losses from two grassland soils
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2002)
Although phosphate phosphorus (P) is strongly sorbed in many soils, it may be quickly transported through the soil by preferential flow. Under flood irrigation, preferential flow is especially pronounced and associated ...
Fractionation of arsenic in soil by a continuous-flow sequential extraction method
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2001)
Batch sequential extraction techniques for fractionating metals or metalloids in soils are time consuming and subject to several potential errors. The development of a continuous-flow sequential extraction method for soil ...
Fractionation of copper, nickel, and zinc in metal-spiked sewage sludge
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2001)
The enrichment or spiking of sewage sludge with heavy metals for experimental purposes is a fairly widely used, although sometimes controversial, technique. A study was undertaken, using a sequential fractionation scheme, ...
Real-time, high-resolution quantitative measurement of multiple soil gas emissions : selected ion flow tube mass spectrometry
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2002)
A new technique is presented for the rapid, high-resolution identification and quantification of multiple trace gases above soils, at concentrations down to 0.01 µL L⁻¹ (10 ppb). The technique, selected ion flow tube mass ...
