Minbos has announced the first season results of its four-year fertilizer trials

The first season results have been received from the Company’s four-year phosphate fertilizer (brand name ‘Prosper Primeiro) field trials in Angola.

Trials were planted across Angola as part of commercial offtake arrangements and government research (agronomic) institutions.

Highly encouraging results have been received, with the average of the nine trials showing no significant difference between the four phosphate treatments which are all statistically better than the control (no fertilizer), confirming the performance of Prosper Primeiro as a direct application fertilizer suitable for use by smallholder farmers, the Company’s initial primary target market.

Latest results confirm 40 years of studies that show high reactivity phosphate rock is suitable for direct application in soils with high acidity and low phosphorus that also receive high rainfall (Angolan soil and weather conditions) and especially effective in long duration crops.

Other key results confirm that Cabinda phosphate rock (Prosper Primeiro) when used as a direct application fertilizer:

• Delivers similar agronomic effects to imported Water-Soluble Products (WSP) products;
• Has a trend for improved performance in the second and third season without additional application (the residual effect); and
• Performs best when it is broadcast and/or incorporated in the soil to maximise the exposure of the phosphate rock to soil acidity.

Previously completed trials have highlighted that Angolan soils are particularly high fixing, which favours the slow dissolution rate of the phosphate rock versus the high solubility of imported WSP fertilizer products.
