Direct exports of phosphorus from fertilizers applied to grazed pastures
(Crop Science Society of America with the American Society of Agronomy and the Soil Science Society of America, 2019-08-21)
Since its discovery in 1669, phosphorus (P) in the form of fertilizer has become an essential input for many agroecosystems. By introducing a concentrated P source, fertilizers increase short-term P export potential soon ...
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 ...
