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.

Aluminum dynamics in nitrogen‐saturated Andisols in Tokyo
Ecological Research, 2023 Abstract The debate over whether forests around the Tokyo metropolitan area are nitrogen (N) saturation persists, as atmospheric N deposition in throughfall has decreased. This decrease is evidenced by a notable decline in samples collected in the 1990s (especially 1991–1992 and 1995).
