I bought it more cheaper (market price around RM70~75), it comes in 10L per bag (approx. 9.5kg). No detail of Nutients wrote at the back, but I have did a direct translation from Japanese to English from a website (as shown below)
But some of the words missing or wrong grammar, anyway hope that you can understand.

(Japanese version)
水質調整底床
-コントロソイルは弱酸性、軟水を好む生体の飼育に最適な環境を提供します。
天然の土壌から作られた多僟能ソイルです。
-Ph を弱酸性に保つと共に硬度の成分を引き下げます。多くの熱帯淡水魚が好む弱酸性軟水環境を作り ます。
-水槽内のろ過繁殖を促進し、水槽の立ち上がリを早めます。底面フイル夕にも使用できます。（水草を植えな い場合のみ）
-粒が固めなので、崩れにくく長期的に使用できます。
-水草にはもちろん魚、エビなど弱酸性軟水環境を好むあらゆる生体に使用できます。
-水草の根まで酸素の豊富な水が行き渡る特殊粒状構造で、水草を密生させたレイアウトにも最適で す。
-流水から出るアクやその他の不純物を強力吸着し、高い透明度を維持します。

(English version)
Water quality adjustment substrate
-'Control Soil' weak acidity, offers the environment which is optimum to raising the organism which likes the soft water. They are the multi nutrients soils which were made from natural soil.
-As pH is maintained at weak acidity, the component of hardness is lowered. The weak acidic soft water environment which many tropical fresh water fishes like is made.
-Inside the tank is too slow propagation is promoted, in regard to standing of the tank is hastened. Base filter - you can use. When (the water plant is not planted only)
-Because the grain is setting, to deteriorate you can use difficult in the long term.
-Of course you can use weak acidic soft water environment for all organisms which such as fish and shrimp like in the water plant.
-With the special granular structure where the abundant water of oxygen spreads, it is optimum to also the layout which grows thick the water plant to the root of the water plant.
-アク and the other impurities which come out of the flowing water it adsorbs powerfully, maintains high transparency.
