"ExploGrow™ represents more than increased yield, crop quality and rejuvenated soil. True sustainable agriculture requires real and safe solutions enabling farmers to cut down on chemical fertilizers, poisons, and using less water. We must, before it is too late, give serious attention to the health and sustainability of our soils. We must now embrace more responsible new farming methods."Mnr Dreyer Senekal, Senekal Boerdery

Root development 4 months after first application of our bio-fertilizer

Five clusters of Sugarcane were take from profile holes.

The root systems treated with ExploGrow™:

  • were more than double in size
  • penetrating the clay soil more than twice the depth

The more than doubling of the root system enhances the plant's ability to absorb nutrients, hence reducing chemical fertilizer requirements, reducing water needs (around -20%) and makes the plant more resistant to extreme heat, cold/frost (through absorption of more minerals) and typically increases the yield and the Brix dramatically.

Increased biological activity: visibly better soil

After only 4 months, soil conditions are already visibly improved compared with the control.

"This is due to the increased biological activity by the 17 microbes in ExploGrow™ and the consequent much larger root systems" Mark Young, BSc.

Soil microbial analysis before and after

Increased soil life:

[Note: Microbial soil analysis was conducted at Rhodes University by Professor Joanna Dames, Department Biochemistry, Microbiology and Biotechnology]

Replicate soil samples were serially diluted, plated onto appropriate media, incubated and assessed for colony forming units (CFU).

Note: The analysis only provides a microbial count per gram soil, no identifications of the microorganisms have been made apart from separation into broad bacterial and fungal categories.

Before: 21 September 2016

  • Total Bacterial Count: 0.25 million
  • Total Fungal Count: 0.002 million

After: 23 February 2018

  • Total Bacterial Count: 20 million (80 times more bacteria)
  • Total Fungal Count: 0.1 million (50 times more fungi)

Enhanced drought stress tolerance: observation

After the sample Sugarcane plants were removed from the soil, the ExploGrow™ treated leaves retained moisture for a longer period (4 hours+) versus the wilting leaves of the untreated Sugarcane. 

"Drought is one of the major constraints on agricultural productivity worldwide and is likely to further increase... Plant growth promoting rhizobacteria (PGPR)* could play a significant role in alleviation of drought stress in plants. These beneficial microorganisms colonize the rhizosphere/endo-rhizosphere of plants and impart drought tolerance". **

Increased leaf mass

The treated Sugarcane has more leaves that are both longer and greener. That results in more photosynthesis (also confirmed by chlorophyll fluorescence measurements below) and more growth over the remainder of the growth cycle till harvest.

Improved leaf photosynthesis

Chlorophyll fluorescence was measured by Marguerite Wescott, MSc, PhD Candidate, Plant Science (pictured) using the Pocket PEA from Hansatech Instruments.

The average Chlorophyll fluorescence in the ExploGrow™ 6 litre/ha came out at +46.1% increase, as compared with the average of the Controls. The +46.1% increase in Chlorophyll fluorescence correlates with the +32.56% increase in yield. The Chlorophyll fluorescence is an indicator of the improved leaf photosynthesis taking place in the plant, due to the enhanced activity of the beneficial microbes.

More data available upon request. 

Sugar content (Brix) increased by +18.9%

[Note: The around "30" reading of the refractometer pictured above, shows Brix measuring well above the average Brix content]

Actual Brix measured 7 days before harvest

ExploGrow™: average Brix: 25.08 (from 24 internode samples)

Control: average Brix: 21.08 (from 12 internode samples)

Actual Brix increase: 4.0 = +18.9% increase

Year on year yield comparisons

[Note: Graph above: 2015 -2017 year on year yield comparisons from the 4 quarters (land 701; 702*; 703 & 704) 
in the 100 ha pivot trial area.] *Land 702 received ExploGrow in 2017.

At harvest: increase in Sugarcane yield (tons per hectare)

  • The control area with 160 kg N/ha, produced 86 tons/ha

  • The area treated with only 1 liter/ha ExploGrow™ and 90 kg N/ha produced 54 tons/ha

  • The area treated with only 3 liters/ha ExploGrow™ and 90 kg N/ha produced 62 tons/ha

  • The ExploGrow™ area with 6 liters/ha produced 114 tons/ha

The main ExploGrow™ area (at 6 liters/ha) produced 114 tons / hectare = an increase of 28 tons / hectare (+32.56% increase)

"The doubling of the root system and the huge amount of Nitrogen activity is just unbelievable!”... "ExploGrow™ is truly a game changer"Mnr Dreyer Senekal – die befaamde suikerrietleierboer - van Senekal Familie Boerdery
