(IPB (Bogor Agricultural University), 2003)
Phosphor (P) is the second esensial element after nitrogen which is needed by plants, however, its ava/i!ahi/ity is a problem in vulcanic ash soils such as Andisol. The objective of the research was to study the effect of ...
Relationship Between Exchangeable Alumunium and Phosphorus Sorption Parameters of Indonesian Acid Soils
(IPB (Bogor Agricultural University), 2004)
In acid soils, phosphorus (P) sorption is generally attributed to hydrous oxides of Fe and Aluminum (AI) particularly in tropical soils with low pH. However, reports concerning the role of exchangeable AI in P sorption ...
Changes in Phosphorus Fractions on an Acidic Soil Induced by Phosphorus Fertilizer, Organic Matter and Lime
(IPB (Bogor Agricultural University), 2000)
One month of incubation experiment was implemented to evaluate the changes of phosphorus fraction in inorganic P (Pi) and organic P (Po) induced by phosphorus fertilizer (KH2P04), cow manure ( manure) and CaC03 (lime). A ...
