The mechanism behind its effectiveness in grass growth lies in the photosynthesis process. Ironite fertilizers aid in the process and bring change.

Chlorophyll, a vital component of plants to support photosynthesis and maintain their green color, is enhanced by some proteins. Enzymes arising from ironite fertilizers synthesize these proteins. Hence, you get an evergreen look on your lawn.

Besides, the pale yellow color of grasses might result from the lack of essential nutrients. Ironite fertilizers compensate for the deficiency and provide vital nutrients, such as iron, potash, nitrogen, and manganese.

The reason behind the pale yellow color of your lawn might not solely be the deficiency of nutrients. It could be due to the unavailability of iron in the soil for planting.

Iron chlorosis is the unavailability of iron for plants, especially in alkaline soils. It is because alkaline soil binds the iron available and makes it deficient in the plant.

Ironite fertilizers act as a temporary fix for iron chlorosis. It provides the unavailable iron, thus making the lawns greener.

But, the effect may last only for a season or two, and it is not a permanent cure for iron deficiency. The efficiency of ironite fertilizers also depends on the type you use.

While the water-soluble formulas last for less than one season, the granular ones last for two to three years. The reason behind this is that plants rapidly use up water-soluble formulas. Hence, they need frequent application of liquid ironite.

What are the Different Types of Ironite Fertilizers?

You can come across two ironite fertilizers, namely organic and synthetic ironite fertilizers. It depends on the source and applications.

Organic ironite fertilizers arise from organic sources, such as greensand and milorganite. Unlike other fertilizers, organic ironite fertilizers mix gradually into the soil. So, they work for long periods. But, the plants readily absorb the iron obtained from these sources.
