Outline of Final Research Achievements

The purpose of this research is to develop technology on resource of phosphorus using mixture of dredged soil and alkali materials. We can find neutralization of acidic soil, reduction of nutrients in the pore water and removal of hydrogen sulfide. Growing rate of tomato in the dredged soil and alkali materials mixture covering humus ground is as faster as tomato grown in humus ground. From the results obtained above, we conclude that covering the mixture of dredged soil and alkali materials can be used as a phosphorus resource in the agriculture.
