Benefits of the Right Iron Applications

Berkshire, England: Iron (Fe) plays an important role in Chlorophyll production, reducing the potential of deficiency and subsequent chlorosis.

According to Indigrow, a Full Business Member of the Asian Golf Industry Federation, there is a very large correlation between Fe availability and colour response in managed turf. The availability of applied Fe is reduced by high pH levels in the soil and spraying water.

Fusion Liquid Fe:

  • Prevents Fe deficiency potential in acidic sands
  • Offers rapid greening effect from Fe application

A spokesperson for Indigrow said: “Ferrous Sulphate (Ferrous Fe2+) is the most commonly used form of Iron used to achieve cost-effective, rapid green up. Unfortunately, as a standalone raw material there are many pitfalls to using it in this basic form for professional turf managers.

“Using the most basic powder form can be more hazardous to the operator and very time consuming. Often, time constraints and the demand for visually pleasing results within days reduces the window of opportunity to spray.”

Even reducing your soil pH by one is enough to increase Iron availability by 100 times.

Obstacles to Nutrient Adsorption and Absorption

  • Spray droplet surface tension can cause bounce off of nutrient solution to the soil surface not adhering to foliage
  • Incorrect droplet size can burst and splash causing run off from waxy cuticle surface
  • Too small droplet size can increase risk of spray drift resulting in irregular coverage
  • Lack of adjuvant creates inconsistent cover layer over cuticle causing uneven distribution
  • Lack of complexing agent or anti-oxidant can lead to premature oxidation reduced efficacy
  • Lack of complexing agent can reduce absorption and penetration

“The advanced formulation in Fusion Liquid Fe helps overcome all of these obstacles ensuring maximum adsorption and absorption of the applied Fe. The important 20% of the formulation adjuvant complexing agent and anti-oxidant which increase the efficacy of the nutrient adsorption and uptake.

“This has a magnified impact on the performance of similar, independently raw materials or products without sufficient formulation aids,” added the Indigrow spokesperson.

Efficiency of Foliar Application with Fusion Liquid Fe

  • Limited interaction with soil reduces potential lock up
  • Foliar applied leaves no visible residues
  • Less nutrient required, making Fusion Liquid Fe seven-to-eight times more efficient than cheaper Fe sources
  • Even application for consistent results
  • Rapid assimilation of Fe fast greening response
  • Added anti-oxidants help stabilise formulation
  • Very high solubility of Fe source and high concentration of Fe
  • Inclusion of adjuvant to optimise droplet size, reduce surface tension bounce, increase spreading, wetting, sticking and penetration
  • Complexing/chelating agent to enhance nutrient availability
