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.
