Iron (Fe)

Products supplying Iron (Fe)

Iron (Fe) is the most important element in plant nutrition and also most commonly deficient element in gardens, particularly in alkaline, organic and sandy soils. Iron can be supplemented through a number of fertilsier sources, but most common products available in the market are Sulphate form of Iron and Chelated form of Iron.

Please note that all Manutec Soluble Trace elements products are of high analysis and provide an excellent value for money. They are easy to dissolve in water and apply. Do it yourself and avoid wasting money on buying diluted low analysis liquid products. 

Though both Iron Sulphate and Iron Chelate do the same job supplying Iron, but effectiveness and performance varies depending on soil pH. Under alkaline pH conditions, applying Iron Chelate is more effective than Sulphate, because under high pH conditions, Iron reacts with Phosphorus and becomes insoluble Iron Phosphate and gets locked up in the soils, reducing its uptake in to the plant’s system which will cause deficiency. Applying Chelated Iron will overcome this issue as Iron Chelate is coated with chelating agent and will reduce the reaction of Iron in soil. Again in chelated form of Iron, there are different types of Iron Chelates depending on type/quality of coating agent. The most common Iron Chelate available in the retail outlets is Iron Chelate-EDTA. However other superior quality Iron Chelates such as Iron Chelate – DTPA & Iron Chelate – EDDHA are also available, but mainly used by professional gardeners & horticultural growers. Iron EDTA is less expensive as compared to DTPA & EDHA chelates.

Using Manutec Iron Sulphate in pots/containers as acidifying material:

  • Iron Sulphate is also an acidifying material, however, as it is not as strong as Sulphur in acidity, for use on a larger area or for reducing high pH value,  may require large amount of Iron Sulphate, which sometimes causes Iron toxicity.
  • However unlike Sulphur, Iron Sulphate is water soluble and hence provides a fast response to reduce pH and it is a good option for small containers and particularly for reducing the pH slightly and quickly.
  • Use a solution containing 2 grams of Manutec Iron Sulphate per liter of water. Apply about 200 ml per liter of mix & then within 5 minutes water thoroughly to drain excess salt. Wait for a week, check the pH, if needed repeat the same.

Foliar Spray: Dissolve at the rate of 1 gram per litre and spary the solution over the foliage thoroughly wetting. Ensure spraying is performed preferably in the morning hours and avoid doing in hot & humid weather conditions.

Note: Though foliar sprays provide a quick relief due to fast absorption and action, the relief to the plants will be very temporary, once the nutrients are utilised, plants again hunt for nutrients from the soil, so it is always advisable to supplement soils also regularly to avoid severity of deficiency.
