Over the past two decades there have been over 45 fully independent replicated trial sites (both plot and paddock size) looking at Australian Mineral Fertilisers (previously Western Mineral Fertilisers) programs and the Grow Safe® products. This has resulted in the collection of valuable research data, used to improve & enhance (i) the fertiliser and biological product formulation, and (ii) the in-field Grow Safe farming programs.
The end result of this R & D are programs that achieve on average the highest net $ return/ha to the farmer, when monitoring yield, produce quality and input costs. It has also demonstrated improvements in soil health through increases in Nutrient Use Efficiency (NUE), Soil Carbon & beneficial microbe levels, and an understanding of the effects of inputs (such as Nitrogen, herbicides and fungicides).
The R&D Team at Australian Mineral Fertilisers have successfully commissioned over 45 scientific investigative trials- statistically designed with replications and randomisations both in pots or on paddocks – conducted by several independent agencies in the past 2o years, evaluating the comparative performance of GrowSafe® Programs and Products across the length and breadth of WA farming geography involving commercial broad acre and pasture crops. The valuable data generated through these trials have been utilised in improving the Bio-Mineral Fertiliser product formulations and Grow Safe® Farming programs for the benefit of farming communities to achieve highest average Net Returns and Gross Profit Margins($$$/ha). These outcomes were made possible through incremental yields of better qualities at significantly reduced production costs along with the added benefits of improved soil health in terms of Nutrient Use Efficiency (NUE), Soil Organic Carbon & Beneficial Microbes- all that constitute the Natural Capital of land –all realised in majority of the cases. These R&D exercises have expanded our understanding of soil health and the possible impacts inputs such as Nitrogen, Herbicides and Fungicides can have.
These trials include:
Title: NUE – Nitrogen Management without Top-up – Wheat
Location: Maya, WA 6614
Result Summary: limiting rainfall that year hindered the trial data. Similar wheat yields across AM Fertiliser and DAP programs. AM Fertiliser and microbial program had the highest nutrient use efficiency (NUE) & lower screenings than DAP programs.

Title: AM Fertiliser program vs DAP program (with no additional N)
Location: Esperance, WA 6450
Conditions: Sandy gravel soils, low pH (4.7-4.9), low organic matter (1.1-1.3%) and higher than average rainfall (>600 mm).
Result Summary: The AM Fertiliser program produced 209 kg/ha higher than the DAP program, averaging 2828 kg/ha – with half the nitrogen and potassium inputs. Beneficial soil microbes increased yield by 32.4% compared to the AM Fertiliser program without soil microbes, and significantly higher than the DAP based treatments with additional liquid N.

Title: Root & Shoot Ratios, Yield and Quality – Nitrogen on Wheat
Location: Tincurrin, WA 6361
Result Summary: The AM Fertiliser program had significantly higher shoot ratios with reduced NPK inputs. AM Fertiliser program yielded 2566kg/ha with input cost of $79.90. District conventional program (15kg/ha urea) yielded 1749kg/ha with input cost of $52.80.

Title: Effects of Pre-Emergent Herbicides on Soil Biology – Wheat Yield and Quality
Location: Pingelly, WA 6308
Result Summary: Direct correlation between beneficial soil microbiology and increasing nutrient uptake, plant growth, harvest yield and growth. The use of certain herbicides dramatically increased or decreased soil microbial biomass; as well as soil Carbon & nutrient availability; and this is directly related to the harvest yield and farm profit.
Conducted by: Living Farm Ag Research & DAFWA
Date: 2010, 2011
Title: Value of Grow Safe Mineral & Microbe Program
Location: Bruce Rock, WA 6418
Result Summary: Net return per hectare was improved by an average of 10.9% when inoculated with beneficial soil microbes. Different applications of nitrogen were applied with varied responses – data trends suggest Liq-N is better as a foliar rather than down the boot.
