Soils of the reclaimed land of the foreshore in the KEIYO RIGION (near CHIBA CITY) consist of sand and silt. The nain disadvantage with this silt is that this soils are not porous and contain salt of high degree.
The results oblained are
1. The order of the dry weight is as follows (1) Silt mixed with sand (1: 1); (2) Loam only; (3) Loam piled up; (4) Sand column; (5) Silt mixed with E B-30 (soil conditioner); (6) Silt mixed with Telnite (Soil conditioner); (7) Silt only.
Healthy growth of grasses is noticible from (1) to (3), while it is not worthmentioning from (4) to (7).
2. In the case of silt, percentage of Chlorine in the upper parts is always higher than the lower parts. In the case of Silt mixed with sand, Telnite and E B-30, percentage of Chlorine is considerably lower than that of silt only.
3. Though the percentage of Chlorine in silt is so high to grow any vegitable, but several roots were found in the bottom of silt (25cm in thickness).
4. From the present experiment it may be concluded that “Silt mixed with sand” and “Loam piled up” will be the most suitable methods for Zoisia matrella (HIMEKORAISHIBA) plantation.
