く、もろい状態になっていた。34 days after the start of the 4th test, the minerals eluted from barley stones activate the roots of turfgrass in the barley stones spraying zone and the barley stone mixed zone using soil improving materials. The amount of grass roots and the amount of root hairs were larger than that of the untreated control grass in which no soil improvement material was applied (see Reference Photos 4 to 7). On the 34th day after the start of the test, the amount of roots and the amount of hair roots in the barley-rice spraying group were superior to those of the barley-stone-containing group and the control group (see Reference Photo 5). In addition, the turfgrass in the barley-mixed zone has a larger amount of roots and hair roots than the turfgrass in the control zone where the growth is poor,
It was good. On the other hand, the soil in the control group was in a fragile state because the aggregate structure was poorly developed as compared with the soils in the barley-stone spraying zone and the barley-stone mixed zone.
