Ongoing testwork continues to confirm the efficacy of KPfértil, the fertiliser product that Harvest Minerals Limited (LON:HMI) plans to produce in bulk from its Arapua project in Brazil.
The results of tests conducted over 180 days on juvenile and mature coffee plants indicate that KPfértil is as effective as traditional fertilisers in supplying potassium and phosphate to plants.

As part of the test, a total of 12 treatments were applied to compare KPfértil to conventional fertilisers as a source of potassium and phosphate.
The tests are continuing.
"These results are excellent and build on the successful tests carried out on rice crops which demonstrated a substantial increase in dry matter production following the application of KPfértil,” said Harvest’s executive chairman Brian McMaster.

“We have identified the coffee growers in the Cerrado Region as an important customer base and tests results indicating that our local, 100% organic product acts as efficiently as imported KCl, a conventional source of potassium, represent a significant outcome for Harvest. We expect further results from these tests over the coming months, but our focus is now on registering KPfértil with the Ministry of Agriculture, Livestock and Supply and achieving our first sales."
