This study was aimed to determine effects of soil organic amendment as plant growing media component on restoration of
planting ground. The changes of soil physical and chemical properties and germination and growth of kentucky bluegrass (Poapratensis L.) were investigated. For treatments, soil was excavated at depth of 0-50 cm (referred as S1) and at depth of 50-100cm (referred as S2). Then the half amount of S1 soil was mixed with the soil organic amendment (coir dust 40% (v/v), bottom ash 25%, leaf mold 25%, vermiculite 5%, carbonized rice hull 5%) at a rate of 6% (v/v) (referred as S1CC) and also the half amount of S2 soil was mixed with the soil organic amendment at a rate of 6% (v/v) (referred as S2CC) on pot in a 16 cm diameter and 14 cm height. The experiment was replicated 3 times with 3 pots per replication in randomized block design, and 100 seeds were planted per pot. In results, there was no significant difference in soil pH among the treatments with a slight decrease in soil hydraulic conductivity. However, in the S1CC treatment, positive increases in soil chemical properties,including electrical conductivity, organic matter, phosphoric acid, total nitrogen, exchangeable cation, and cation exchange capacity. Also, the germination rate, plant height, and number of leaves were higher in the S1CC treatment than those in other treatments. These results suggest that the addition of organic amendment to the soil at depth of 0-50 cm might be proper for restoring planting ground.
