The pattern of growth in 10 Japanese cedar (Cryptomeria japonica) trees (age 162 to 255 years) located within a natural forest was analyzed using ring-width data. These trees showed a rapid increase i...
Retardation of Nitrogen Leaching by the NO3– Adsorption in the Subsoil in a Watershed of Old Japanese Cedar and Cypress Stands
anion adsorption column experiment forest cutting subsoils volcanic ash soils
2009/8/25
Volcanic ash soils contain appreciable quantities of anion adsorption capacity (AEC) due to the variable charge, and they adsorb anions by non-specific adsorption. To study the effect of this characte...
