Ginger cultivation in continuos cropping system causes reduce of the quality and productivity of ginger mainly due to root-rot disease. Thus, this study was conducted to investigate applications of selected green manure crops and charcoal on changes of ginger growth depending on changes of soil physical and chemical properties. As comparing between soil physical and chemical properties after harvesting the ginger plants and those before planting them, the bulk density increased from 1.18∼1.30 g cm-3 to 1.33∼1.44 g cm-3. The concentrations of total nitrogen, exchangeable Ca+, exchangeable Mg+ increased, whereas soil pH, electrical conductivity (EC), available P2O5, exchangeable K+ concentration, and ion (Fe), manganese (Mn), and zinc (Zn) concentrations decreased. The concentrations of phosphorus, potassium, magnesium, manganese, and zinc in the subterranean part of ginger plants were higher in most of the plots treated with green manures and charcoal than in the untreated plot. Also, the concentrations of inorganic elements in ginger plants were higher in the plots contained high clay content than in the plots with lower clay content, except in the untreated plot. The concentrations of phosphorus and potassium were lower in rotten roots than in healthy root, but the concentrations of nitrogen, calcium, magnesium, iron, manganese, copper, nickel and zinc were unexpectedly higher in the rotten roots than the normal roots. In particular, the concentrations of ion and manganese in the rotten root of ginger plants in specific plots increased from 417.4 mg kg-1 to 1950.5 mg kg-1 and from 85.2 mg kg-1 to 537.1 mg kg-1, respectively. The concentrations of nitrogen, phosphorus, potassium and magnesium in the aerial part of healthy ginger plants were higher than in that of ginger plants with rotten root. The concentrations of calcium, ion, manganese, copper, nickel, and zinc were higher in the aerial part of ginger plants with rotten root. For these reasons, ginger productivity was improved from 2.8% to 41.7% with the applications of green manure and charcoal, however, the productivity and growth of ginger plants were more affected by clay content of soils than treatments of green manure and charcoal in the plots.
