After seeing the positive effects on other crops, the farmer added SumaGrow (referred to as ExploGrow in report) to his normal fertilizer program, treating all his potatoes. He left no control areas, comparing only year to year results. SumaGrow was applied by pivot irrigation between 8 and 10 liters per hectare. 88 tons per hectare were achieved on one of the 18 potato lands.
Remarks from the farmer:
- “Very happy with the yield, quality and sizing that was much better than normal year-on-year averages”
- “The potato plants we’re growing so well (healthy and strong) that they looked like they had a few more weeks left in them to produce even more tons per ha, nevertheless we harvested on the scheduled dates”
- “ExploGrow has become an integral part of our fertilizer program, going forwards, we will be reducing chemical fertilizers and trialing slightly longer growing periods”
The farmer invited us to bring any serious potato farmer to “come and see for themselves”.

The photos were taken on a different potato farm in the Limpopo Province. The potato plants in these photos were also treated with SumaGrow with a special blend of beneficial soil microbes. The owner of this potato farm was also particularly impressed by the large sizing that resulted in a better overall yield.






Small trees in the nursery treated with Explogrow (SumaGrow) which were on the left, dramatically outperformed the untreated trees on the right.
Stem diameter of treated Pecan trees averages 1cm. Untreated Pecan trees stem diameter averages 0.6cm.
Groundnut is a major oil-seed crop in South Africa. About 200,000 ha are planted annually, producing an average yield of 1,000 kg/ha. In South Africa, Groundnut yields are not only limited by low and late summer rains and poor soils, but also by many diseases including those caused directly or indirectly by plant-parasitic nematodes. Indirect damage may include increased secondary infection by fungi and reduced nodulation and nitrogen fixation. SumaGrow has shown to be effective in significantly alleviating the underscored factors.
Harvesting actually began 9 days earlier than normal and the stems were thicker than normal in many cases (shown on the right). The mustard greens shown below are a 60 day crop, but 5% of the crop were ready to be harvested 10 days early.

On October 17th, Aidy applied 10 gallons of SumaGrow with no inputs to the 15 acres of the Long Run Fields. The fields were planted with Baby Bok Choy, Yu Choy and Mustard Greens. Organic fertilizer (chicken manure) was applied to all 15 acres at half the normal rate.
they had experienced a much faster harvest times on the Short Run Field and were also looking forward to harvesting the Long Run field. As you can see, the Long Run Field did very well.
