SASRI has developed a user-friendly internet-based application called OptiFert. This tool enables growers to quickly determine the most cost-effective and suitable fertiliser options for specific NPK requirements. Given that fertilisers represent one of the largest expenses in sugarcane farming, optimising their use is crucial.

While calculating fertiliser types and rates is typically straightforward, it becomes complex when comparing multiple products and prices across various fields with different nutrient needs. OptiFert simplifies this process, providing answers within a few clicks.

Users input their nutrient requirements (as determined by a laboratory), select preferred or available fertilisers, and input current fertiliser costs. OptiFert then displays recommended fertilisers, required volumes, expected nutrient surpluses or deficits, and the total cost of the combinations. Selections can be easily modified to compare different choices.

Even when external nutrition service providers are used, OptiFert allows growers to conduct their own assessments and cross-check the advice received, thereby ensuring optimal decision-making.
