Abstract
Comparison was made between fused phosphate and superphosphate in the manurial value for barley, cultivated on the field of manganese-deficient area, Kamiide-village, at the foot of Mt. Fuji. Results were as follows. 1) Fused phosphate increased pH of the soil, and decreased the amount of available manganese. Barley was damaged by the deficiency of manganese. 2) By dressing manganese fertilizer, the yield of barley was recovered, especially in the case of being overlimed.
