The color of Ferropol depends on the pH value. Ferropol is adjusted to a pH value of 4.5 during production. At this pH value, the color is olive green. During prolonged storage, and especially when bottles are opened, oxygen from the air enters the fertilizer over time, causing the pH value to rise and the color to change to a brownish tone. This has no effect on the effectiveness of the fertilizer or its ingredients. It can continue to be used without hesitation
