Harvest Minerals' focus has been on completing the first round agronomic test work so that an application for certification of KPfértil as a remineraliser can be submitted to the Brazilian Ministry of Agriculture, Livestock and Supply (MAPA). KPfértil is an organic, multi-nutrient slow release fertilizer and remineraliser produced from a weathered potassium and phosphate rich lava, which offers many economic and agronomic benefits.
