Crop Update: Growing Citrus with organic microbial bio-fertiliser

Organic Citrus ~ replanted tree survival rate

Lead Organic Citrus farmer improves tree survival rate (after applying ExploGrow) to almost 100% (up from 50%), around 3 years after replanting new Organic Citrus trees into “very old citrus soil”. 

Due to Organic growing restrictions on the use of chemical poisons/fertilisers, this farmer’s previous optimal survival rate was around 50%.  The Citrus trees from the block treated with ExploGrow™ are also carrying much more lemons versus the control. Further update expected soon with regard to yield, Brix and citric acid levels.

Photos: taken 10 days apart with slightly different lighting. Along with the improved survival rate, there is also a remarkable difference visible with naked eye. The farmer (based in the Sunday's River Valley) invited us to bring any serious Citrus farmer to "come and see for themselves". Please contact us if you would like to arrange an appointment. 

Anticipated results for Citrus using ExploGrow™ 

  • an increase in yield of around 30%
  • reduction in N-P-K fertilizer requirement 
  • reduction in watering requirement
  • increased Brix and citric acid
  • soil condition and plant health optimised
  • the ExploGrow™ effect is even more remarkable when Citrus trees are treated from earlier growth stages

For optimal results, ExploGrow™ should be applied as early as possible, both in the nursery and when replanted, during years 0 - 5.

Stem diameter +22%ExploGrow™ treated 4.5mm, Untreated 3.7mm (9 weeks after the 1st application)

Increased root mass: over 100%  ExploGrow™ treated > 2,000mg; Untreated < 0,999mg

Improved growth rate: 19% Matured for replanting: ExploGrow™ treated: 19/100; Untreated: 16/100

Faster growth rate regarding seedlings and young trees:

  • rapid doubling of root system within 2-5 months versus control
  • increase in stem diameter growth: around 30% + (within 12 months)
