Analysis of potentially mobile phosphorus in arable soils using solid state nuclear magnetic resonance
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2002)
In many intensive agroecosystems continued inputs of phosphorus (P) over many years can significantly increase soil P concentrations and the risk of P loss to surface waters. For this study we used solid-state ³¹P nuclear ...
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 ...
