Little is known about the relationship between soil phosphorus (P) forms of semiarid wetlands and surrounding upland land-use patterns. Soil P in different depths of four wetlands was fractionated using a modified Hedley fraction method. The wetland soil cores were sampled along a gradient of sand desertification in the west of Songnen Plain (Northeast China), and sectioned with high-resolution (2-cm...
Little information exists on phosphorus (P) forms in Histosols or Spodosols, particularly wetlands situations. The objectives of this study were to: investigate concentrations and proportions of P forms in depressional (with Histosols) and riparian (with Spodosols) wetlands, correlate the content of P forms with basic soil chemical properties, and establish general differences in P forms influenced...
