Why Use Foliar Fertilizers?

Plants get the majority of their nutrients from the soil by root absorption.  However 

there are many instances where foliar nutrient supply is both necessary and beneficial:

  • To minimise environmental impact. The usage efficiency of foliar applied nutrients is higher than soil applied nutrients. This can be important in environmentally sensitive areas and areas prone to leaching.
  • To prevent or cure transient nutrient deficiency when nutrient demand exceeds root uptake rate. This may be due to poor root development or rapid crop growth.
  • To by-pass soil conditions which limit nutrient availability and to thereby accelerate plant response. These conditions include adverse soil pH, moisture, texture and aeration.
  • To target nutrients directly rather than rely on indirect transportation through the soil and roots. Examples of this are in preventing nutrient deficiencies of specific organs, e.g. fruit.
  • To supply nutrients to plants with deep root systems, when soil surface application of fertilisers such as P, K, Ca, Mg and trace elements is not effective.
