Note (General): A study on soil improvement for planting teak (Tectona grandis) was carried out at Northeastern Forest Seed Center, Ban Had District, Khon Kaen Province, Thailand. The experimental design was randomized complete block with 3 replications. The trees were planted at 2 m x 4 m spacing. Five different soil improvement methods (treatments) were applied, including 1) Control (no treatment) 2) Application of dolomite (400 kg/rai) 3) Application of dolomite (400 kg/rai) and organic fertilizer (1 kg/tree) 4) Application of dolomite (400 kg/rai) and chemical fertilizer (100 g/tree x 2 times) and 5) Application of mixed fertilizer (dolomite + organic fertilizer + chemical fertilizer at (100 g/tree x 2 times). Height of the trees was recorded. The composite soil samples in each subplot prior to application of soil improvement materials were collected and analyzed for some chemical and physical properties. The surface soil moisture in each subplot was measured using theta probe type ML2x. The preliminary results showed that there was no significant difference in height growth of teak at 15 months after planting. There were no significant differences in almost all studied soil properties except for soil pH and organic matter.
