Growing Citrus: Orange Tree Seedlings

Preliminary test

Seven month old orange tree seedlings treated with ExploGrow™ on 15 September 2015

Photo taken nine weeks after the first application of our organic, poly-microbial liquid bio-fertilizer.


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

9 Weeks after treatment: "We are replanting 19/100 trees from the left [ExploGrow™ treated Orange Trees] and 16/100 trees from the right [untreated]."​Testing Citrus Farmer

Valencia Orange Trees

Preliminary ExploGrow™ Field Test:


Photo: left: untreated, right: ExploGrow™ treated.
Treated on 15 August (photo taken 18 November)

Early observations: Despite the overexposure of the photo on the left, as per the photo below, the Valencia tree on the right appears to have a higher density of leaves that are also richer in colour. As mentioned above, the testing farmer observed many more buds on the ExploGrow™ treated tree.


Photo: left: untreated, right: ExploGrow™ treated.
Treated on 15 August (photo taken 18 November)

Early observations: The leaves from the Valencia trees on the right appear to be richer in colour with a higher leaf density. Significantly, the testing farmer pointed out that the Valencia trees on the right, have many more buds than the trees on the left.

Potential implication for exports: In the event that ExploGrow™ treated Valencia trees produce export grade (larger oranges with higher Brix), it would open up currently inaccessible European markets for Valencias to our testing farmer.

Anticipated results for Citrus using ExploGrow™ (with N-P-K reduction of at least 50%)

  • a increase in yield of around 30%
  • 20 % - 25% reduction in watering requirement
  • around 30% - 35% % increase in Brix

Also note regarding seedlings and young trees:

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