Pecan Nut Trees: full cycle control test results

First Pecan Nuts full cycle control test results in South Africa, 29 July 2015

With N-P-K- application reduced to 50% of recommended quantities, the use of ExploGrow™ is essentially cost neutral.

Mr. Pozyn experienced, by the use of ExploGrow™, an overall net gain of around R37,000 per hectare.

“As a farmer, I'm sick of gimmicks promising the world! What we need is a new concept with control test evidence and research to back it up. In my view, ExploGrow™ is a game changer.”John Pozyn, a Nut famer for 13 years

Improvement in yield:

ExploGrow™ treated trees produced an estimated 5kg to 8kg extra per tree, compared with the untreated trees.

This increase equates to around 25% improvement in yield.

Improved quality grading:

The size of the Pecan Nuts is also dramatically better. This places the product in the top category, resulting in the farmer being paid R11.50 more per kg, equal to a financial gain to the farmer per tree of around R290, adding up to R29,000 per hectare.

This increase equates to a 50% improvement in sale price.

Improved growth rate:

After 11 months(trees planted 15 August 2014), the ExploGrow™ treated trees already appear to be one year ahead in its growth cycle compared to the control.

The significance for farmers would be to achieve the 1 ton per hectare at least one year faster than the normal 5 years.

The significance for nurseries is that they would be able to sell trees on to farmers after 3 years instead of 4.

By implication, a nursery producing 100,000 trees is likely to bank approximately R17,500,000 one year faster when using ExploGrow™.

The increased yield and price equates to a total increase of 75% value per hectare.

This result is without taking into account the faster growth rate.

Damage control observations by Mr Pozyn:


“I [also] treated Pecan Nut Trees infected by Alternaria with ExploGrow™. At this stage my trees look like they are winning the battle. The dieback has stopped and new leaves are forming. I can’t say that ExploGrow™ has 100% cured my trees, just that for now, we are on the right track” John Pozyn
