abstract
 マンガンの多量に集積した土壌に牧草を栽培し,これに硅酸石灰を施与した場合,牧草育ならびに牧草のマンガン吸収lこ如何なる影響があるかを検討し,つぎの結論をえた.
1) 硅酸石灰の施与は土壌よりのマンガン溶出を低下せしめ,牧草によるマンガン吸収を抑制する.
2) 硅酸石灰の施与による土壌マンガン溶出の抑制効果は土壌pHの上昇によるものと,可溶性硅酸
の土壌中における濃度の上昇によるものと考えられる.
3) 植物によるマンガンの吸収に 対して,硅酸は明確な効果はもたないようである.しかし,これに
反し,石灰イオンは桔抗的効果をもち,植物によるマンガン吸収を低下せしめた.
4) 以上のことより,マンガン集積土壌に生育する牧草のマンガン過剰吸収に対する硅酸石灰の施与の効果は,土壌よりのマンガン溶出lこ対する可溶性硅酸の添加の抑制効果ならびに土壌pHの上昇による溶出抑制j効果と,石灰イオンの土壌溶液中の上昇にともなう,植物によるマンガン吸収に対する拮抗的抑制j効果よりなるものと考えられる.
abstract
Experiments on the elution of manganese from soil and pot cultures were performed in order to determine what effects of calcium silicate application to the soil enriching manganese under the paddy field condition on the growth and manganese absorption of pasturage crops would appeare.

1). Amounts of manganese eluted from soil were suppressed by application of calcium silicate, due to the raising of soil pH and also of soluble silica concentration in soil.
2). Application of calcium silicate did not result in increasing of pasturage crops yields but rather in lowering of mangagese concentrations in plants. In the case of none phosphorous application, this
lowering effect of calcium silicate application of contents of manganese in plants was more noticeable.
3). Addition of silica sol to culturing solutions did not affect manganese concentration of pasturage crops but of calcium ion did.
4). Therefore, raising soil pH and soluble silica concentration in soil will result in decreasing the elution of soil manganese, especially of exchangeable mannanese. Calcium ion would have a direct, that is, antagonistic effect on the absorption of manganese by pasturage crops.
