This research is using soil and by adding Polyvinyl Alcohol Fiber and Coir- Fiber in different percentage, samples are made in different percentage and contained percentages glue’s quantity by compressing in to a fixed volume by high temperature. According to physical and chemical tests, we suppose to find the best growth condition. At least we suppose to replace the soil culture medium. The research shows when adding coir-fiber 50% and PV A fiber2%, it is suitable for soil culture. The coir fiber percentage effects volume reducing percent, water losing percent, three kinds of capacity percent and pH value.
