Competitive sorption of molybdate and phosphate in Andisols [PDF]
Journal of soil science and plant nutrition, 2012 Abstract We have examined the effects of both pH and phosphate concentrations on molyb-date sorption by four Chilean Andisols with varying chemical properties. For both anions adsorption decreased with an increase in soil pH and also with organic matter content in the soils. In general, more phosphate than molybdate was sorbed by the soils.

Unravelling upbuilding pedogenesis in tephra and loess sequences in New Zealand using tephrochronology [PDF]
, 2010 The genesis of soils developed in either tephra or loess on stable sites differs markedly from that of soils developed on rock because classical topdown processes operate in conjuction with geological processes whereby material is added to the land ...
