Research Abstract

Sugarcane growth experiment was conducted using soil deposited in sedimentation tanks. As a result, the sugar content of sugarcane applied AM fungi was significantly higher than the control sugarcane at the 0.05 probability level. The result suggests that the phosphorus included in the deposit was used to sugar synthesis of sugarcane by the AM fungi action.
