Abstract:In the soil test, it is found that T the content of clay particle taken from the TM-85 soil density gauge is 2-5% more than that obtained with the transfer pipet formerty used. Here four TM-85 gauges are studied one by one and corrected with regard to the reading, falling distances and curving surface, which may be a reference for colleagues.
