Tests Conclude the GQ Blends Are a Recommended Replacement for Imported Chemical Fertilizers

VANCOUVER, BC--(Marketwired - November 04, 2015) - Great Quest Fertilizer Ltd. (TSX VENTURE: GQ) (FRANKFURT: GQM) ("the Company") is pleased to announce that it is in receipt of the quantitative results from product trials conducted during the 2014/2015 growing season. As expected, our products continued to perform well generally, in line with, and in a number of cases significantly outperforming the commercially available higher priced imported chemical fertilizers.

• GQ35 NPK blends perform in line with DAP, recommended replacement
• Isolated GQ27 performs in line with DAP, recommended replacement
• GQ Fertilizers outperform in residual impact, recommended use to restore soil health

In head to head comparisons the GQ products exceeded expectations. The Great Quest fertilizer products are semi soluble fertilizers, 71% soluble in mild acid. Comparatively chemical fertilizers are 100% in the same acids, meaning the full nutrient load is not expected to be available to plants that are fed using the GQ phosphate fertilizer. On average the GQ fertilizers had 94% of the yield of chemical fertilizer in directly comparable tests, at 71% of the measured solubility and 50% of the expected market price. The study completed by the Institut d'Economic Rurale (IER), a division of the Ministry of Agriculture, analyzed crop response to multiple formulations of the GQ phosphate fertilizers, as crop dosage recommendations were analyzed. Presented in this release are all of the directly comparable results, other formulations will be made available on SEDAR.

The study comprised of 49 agronomic trials covering the five major agro-ecological regions of Mali, where large-scale commercial agriculture occurs. For 2014/2015, six trials were added in the Northern zones Tombouctou and Gao and though only subsistence agriculture occurs in these areas, the company hopes to participate in agriculturally focused development programs in these areas. Tests were performed on Mali's most important crops, namely Cotton, Corn (Maize), Rice (Irrigated, Rainfed and Submerged varieties), Millet, Sorghum, Cowpea (or Black-Eyed Pea), and Peanut.

The following results compare yields of the listed crops using 100kg/ha dosages of the most common fertilizer blend N 15 - P 15 - K 15. The commercial blends using diammonium phosphate (DAP) for the contained phosphate (P) is compared to the GQ formulation using our processed direct application phosphate for all of the contained P. Both of the blends have identical concentrations of the nitrogen (N), phosphate (P) and potassium (K) nutrients.

The GQ 35 formulations performed in line with the DAP blends with particularly strong showings in rice, peanuts and wheat. Rice is the single most common crop grown in the country. Results concluded there is no statistical difference between the GQ35 and DAP yields, and the lower cost GQ product is a capable replacement for more expensive chemical imports.

In the same way blends for cotton were compared, however commercial cotton growers use what is called 'complex cotton' NPKSB 14-18-18-6-2 adding sulphur and boron to three major nutrients, at a concentration of 150kg per hectare compared to 100kg used for other crops. Again results concluded there is no statistical difference between the yields using GQ35 and DAP blends, in what was a challenging year for cotton crops. When cost and residual impact are factored (reported in table 4) evidence favours use of GQ35 blends.

The following results compared the yields of 27% P2O5 medium grade granulated GQ phosphate (GQ 27%) with market available DAP. These trials were not quite equal owing to the Malian researchers mimicking the strategy of regional farmers substituting available DAP fertilizer for the recommended fertilizer super soluable phosphate which is not available in West Africa. Crops fed GQ 27% received 27 kg of P nutrient and no N or K per hectare and the crops fed DAP received 20 Kg of P and 7 kg of N.

Here the GQ 27% marginally outperformed the DAP however, for the cowpea and peanut nitrogen is not required soil nutrient so the larger P dose should give the GQ an advantage.

As a part of the study the IER Researchers investigated the residual impact of the fertilizer on crops planted on plots that had used the fertilizer the year before, but had no new fertilizer added for this growing season.

In these trials the GQ fertilizers outperformed, dramatically so in the case of corn. This is expected given the semi-soluble nature of the fertilizer; this allows it to stay in the soil and be available for the next crop. It makes for a very compelling case for farmers to use the GQ formulations, lower upfront cost, equivalent yields in the first year and an opportunity for significant outperformance the longer they use the GQ product.

Dr. Lamine Traore, Agronomist and Microbiologist, Research Program Lead from IER, concluded, "The results of this year's trials have demonstrated yet again that the granulated fertilizer products GQ 27% and GQ35-NPK have similar yields to those of the commercially available fertilizers right from the first year of application. The low coefficient of variation observed in the results from region to region where the products were tested, is an indication of the consistent efficiency of the Great Quest products."

Commenting, Jed Richardson President and CEO, "These results reaffirm our belief in the strength of our product. The GQ blends are well poised to provide farmers in Mali and the sub region with a cheaper alternative that matches the performance of expensive imported fertilizers, with an expectation of exceeding that performance for certain crops in some regions, while repairing soil poverty for future crops. Food security is an acute problem in the region and the results indicate that GQ blends may very well become part of the solution."
