Potential and Possibility of Direct Use of Guano as Fertilizer in Indonesia
(2007)Guano is a material originally from sea bird or bat excrement. This material is an important source of P fertilizer during nineteenth century and the early part of twentieth century. The development of artificial fertilizers ... -
Predicting Spatial Distribution of Argilic Horizon Using Auxilary Information in Regional Scale
(2005)For supporting better soil management, the spatial distribution of soils having argilic hori=on (argilic soils) must be recognized and it can be delineate in soil survey mapping activity, but this activity consumes much ... -
The Rate of S-Element Transformation to Sulfate on Three Kinds of Soils with and Without Addition of Organic Matter
(2005)Defiency of sulfur were found at many areas of farming in Indonesia. The aim of this experiment was to Icnow the rate of S-element tranformation to sulfate on three kinds of soil without and added of organic matter. The ... -
Relationship Between Exchangeable Alumunium and Phosphorus Sorption Parameters of Indonesian Acid Soils
(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 ... -
