30% Yield Increase With Reduced MAP + Liquid Fertiliser
Information
This trial is characteristic of the sort of trial initially conducted by many of Microsoil’s clients. It was set up as a simple demonstration trial to look at the impact of reducing rates of granular fertiliser and toping them up with a program of Microsoil liquid fertilisers. As shown in the graph, the trial compared conventional rates of applied granular synthetic fertiliser to granular synthetic fertiliser + liquid fertiliser. This highlights the typical approach that Microsoil takes to dryland cropping – a reduced rate of MAP/DAP etc in conjunction with boom applied liquids with a view to maximising fertiliser use efficiency. The above Gross Margin figures take into account both the cost of fertiliser applied against the canola yield. The district average for canola yield in this region was 1.6 tonnes. Trial conducted by: private client trial.

Reduced MAP In Canola Trial
A private client canola trial, conducted in Junee, NSW, examined the impact of reducing granular fertiliser rates while supplementing with Microsoil’s liquid fertiliser program. The trial aimed to maximise fertiliser efficiency and compare yield and gross margin performance between traditional granular fertilisation and a reduced MAP program with Microsoil liquids.
The trial compared two treatments:
- 80kg MAP (Control) – 2.2 t/ha yield, $1,048/ha gross margin
- 50kg MAP + Microsoil Crop Starter & N-PLUS – 2.85 t/ha yield, $1,340/ha gross margin
Despite using 37.5% less granular MAP, the Microsoil-treated plots outperformed the control, producing an additional 0.65 t/ha in yield and delivering a gross margin increase of $292/ha. This demonstrates that reducing MAP rates while incorporating Microsoil liquids enhances nutrient efficiency, allowing farmers to improve profitability while minimising upfront fertiliser costs.
The trial also highlighted Microsoil’s ability to enhance phosphorus availability and support plant growth throughout the season, rather than relying solely on high early-season MAP applications. Given that the district average for canola yield was 1.6 t/ha, the results reinforce how Microsoil’s liquid fertiliser program can significantly outperform traditional granular-based approaches.
For canola growers looking to reduce fertiliser costs without sacrificing yield, Microsoil’s combination of reduced MAP rates and liquid fertilisation provides a sustainable and profitable alternative to conventional fertiliser programs.
