NutrientStar to provide data on efficiency products
Declaring that nitrogen fertilizer is one of the most important inputs in agriculture, but that up to half is going to waste, the Environmental Defense Fund (EDF) recently launched NutrientStar, a new independent, science-based program that will review the performance of commercially available nutrient management tools.
The Fertilizer Institute has been involved in an ongoing dialogue with EDF on NutrientStar. “We have members whose products are being evaluated,” said TFI spokeswoman Kathy Mathers. “We share the same high-level goals of helping farmers manage our products in a sustainable manner, and as such, we will continue the dialogue.”
EDF noted that much has been done already. For one, major food companies are launching sustainable sourcing programs to reduce fertilizer runoff, improve air and water quality, and reduce the risk of supply chain disruptions. Many of them, including EDF, have joined Field to Market, a diverse alliance of over 200 entities pursuing sustainable agriculture across the supply chain. Fertilizer industry members include associations TFI and Agricultural Retailers Association, as well as several major fertilizer companies. Several major retailers, such as Walmart and food suppliers are also members. Walmart, McDonald’s Corp., and PepsiCo were early advocates of sustainability (GM Aug. 16, 2010).
EDF says little data is publicly available on how these tools work in the field. “NutrientStar will showcase how well products work in real-world farming scenarios,” said Karen Chapman, agricultural sustainability project manager at EDF and administrator of the NutrientStar program. “This isn’t really about the fertilizer industry. It’s about holding agricultural service providers – people who make the tools and products and decision support systems for fertilizer management – to a common standard and assessing the performance of the tools they offer against that standard in a more transparent fashion than we currently have today. Farmers don’t see the data on performance of these tools. They are being marketed tools without clear knowledge of their benefits. NutrientStar’s independent science review panel will conduct rigorous assessments of all tools on the market, particularly looking at on-farm field trials, to determine how a tool works in croplands, in different regions, and on different soil types.”
Chapman pointed out that fertilizer management tools to be reviewed through NutrientStar include enhanced efficiency fertilizer compounds, such as nitrogen stabilizers, and decision support tools, such as optical sensor technologies or models used to aid nutrient applications in the field.
Tools and products assessed or soon to be assessed include Adapt-N, which is an online software made by Agronomic Technology Corp. using a linked crop model and soil model to estimate nitrogen rates for individual fields or areas within fields; N-Serve by Dow AgroSciences; and Agrotain, Agrotain Plus, and Super U, made by Koch Agronomic Services. Reviews being made public this spring include Nutrisphere N by Verdesian Life Sciences, Instinct II by Dow, and ESN by Agrium Inc., as well as those for dicyandiamide (DCD) and thiosulfate, and Slow Release Foliar N products made from methylene urea.
Assessments later in 2016 will focus on Fieldview Pro Nitrogen Advisor made by Climate Corp. and Encirca by DuPont Pioneer
“NutrientStar is the first-ever review program to provide farmers, their advisors, and agricultural supply chain companies with reliable data on the performance of these popular tools,” noted John McGuire, EDF advisor and precision agriculture expert. “Farmers need certainty that the tools they purchase will work as advertised.”
An independent review panel composed of leading soil and agronomy scientists from across the country will establish the criteria for NutrientStar review. The panel assesses tools based upon available data demonstrating their ability to improve nutrient use efficiency, defined as unit of yield over unit of applied nutrient, in the field. NutrientStar review will also show yield impacts from use of a tool and summarize key characteristics important to farmers and advisors such as cost/benefit, ease of use, and required data inputs.
The NutrientStar program also will establish guidelines for field testing nutrient-use efficiency tools, setting standards and providing a geographical framework that can substantially advance the research agenda in ways that will benefit the entire agriculture industry.
Despite some media reports that have likened NutrientStar to a Consumer Reports-style rating service, that is not the case, NutrientStar Communications Manager Christina Mestre told Green Markets. She said as of now, NutrientStar will not rate or endorse any tool or product. Instead, she likened it more to Car Fax.
“NutrientStar will report on the availability of data and the extent to which it is possible to make a determination of nutrient use efficiency benefits based on that data,” said Mestre. “However, farmers, ag retailers, and other practitioners can use the assessment information to choose the best product for their needs. The website will provide data on a tool’s ability to improve nutrient use efficiency.
“We also encourage companies to seize the opportunity to share data that documents the efficacy of their product using robust testing protocols established by NutrientStar, thereby increasing transparency and consumer trust,” Mestre added.
