Using Korteweg-de Vries (KdV) equation, solitons are investigated in a dusty plasma consisting of positive ion, negatively charged dust grain and Boltzmann distributed electron. Both compressive and rarefactive solitons are found to exist in the dusty plasma for fast and slow modes. Greater ( is the number of elementary charges residing on the dust grain) is found to yield higher amplitude solitons. Further, it is observed that higher temperature ratio gives higher amplitude in case of slow mode and gives smaller amplitude in case of fast mode.
