Iron, an important nutrient element for plants, converts into insoluble iron hydroxide or iron carbonate compounds in calcareous and high-pH soils. These compounds cannot be taken up by plants because they do not dissolve in water. For iron fertilizer applied to soil to be effective in high-pH conditions, it needs to maintain its stable structure and not convert into hydroxide or carbonate.

Ferrol PlusTM has been developed through years of effort. It maintains its stable structure over a wide pH range and remains effective for a long time.

For all plants: It is used through soil application.
