The problem is, farmers and their agricultural advisers have little way of knowing which tools perform as advertised without potentially costly, time-consuming trial and error – the only information available on many tools is limited to marketing materials with sparse data. At the top of the supply chain, big companies that are setting goals for fertilizer optimization find it difficult to verify their suppliers’ progress.
Enter NutrientStar. NutrientStar is an independent, third-party program that determines just how effective nutrient management tools are at helping farmers optimize their fertilizer use – and potentially save on input costs.
To provide farmers and their advisors with the best available information about performance of existing and emerging fertilizer management tools and products so they can choose those best suited to increase productivity, profitability, and environmental outcomes on their fields.
We’re here to help your organization meet its business and sustainability goals through NutrientStar. We work with companies throughout the review process, plus we’re available to food companies, crop advisers and farmers who want to learn how NutrientStar can benefit them.
