SPOTLIGHT: Fertiliser calculator

The Department of Agriculture and Food, Western Australia (DAFWA) have recently upgraded their online fertiliser calculator tool. The free calculator is designed to guide decisions on which fertilisers represent the best value for money while meeting crop nutrient requirements.

The calculator allows comparisons of 1500 commercially available fertiliser products for their nutrient content and cost, and provides information on the compatibility of different fertilisers when mixed together.

Registered users can develop fertiliser programs and create their own customised records of fertiliser applications, rates and costs. This tool could be especially valuable for growers and advisors who design and run on-farm fertiliser trials or test strips.

The calculator is free to use, and was developed by DAFWA, with funding from Horticulture Australia’s ‘Continuing on-farm improvements through good practice demonstration and extension’ project.
