EU Extends Transition Period for Coated Fertilizers

Why the Transition Period Has Been Extended

The European horticultural and fertilizer industries have received a significant development regarding the implementation of the requirements affecting coated fertilizers under Regulation (EU) 2019/1009. Following extensive discussions between industry stakeholders, scientists, and regulators, the timeline for compliance with the biodegradability requirements applicable to fertilizer coatings has been extended from the previously anticipated 2026 milestone to 2028. The broader regulatory framework remains established under Regulation (EU) 2019/1009, which aims to make fertilizing products more sustainable and environmentally responsible across the European market.

For manufacturers of controlled release fertilizers (CRFs), the extension comes as a welcome opportunity rather than a relaxation of the environmental objectives. The challenge remains exactly the same: develop coating technologies capable of delivering reliable, predictable nutrient release while ultimately degrading completely in the environment after they have fulfilled their function.

The Challenge of Developing Biodegradable Fertilizer Coatings

Over the past few years, many within the industry have come to recognize the extraordinary complexity of this task. The coating is not merely a packaging material around fertilizer granules. It is a highly engineered component responsible for controlling nutrient release over periods that may extend from several months to more than a year. Maintaining that level of precision while ensuring complete biodegradation after nutrient release has ended is proving to be one of the most demanding research projects the sector has ever undertaken.

The environmental rationale behind the requirement is broadly understood and supported. European regulators are seeking to minimize the accumulation of persistent materials in the environment while encouraging innovation toward more sustainable technologies. Few stakeholders question these objectives. The real question has always been whether science and industrial development can deliver solutions that meet both agronomic and environmental expectations at the same time. Regulation (EU) 2019/1009 itself reflects the EU’s broader ambition to promote sustainability, resource efficiency, and circular economy principles within the fertilizer sector.

What the Extension Means for Growers and the Industry

The additional two years are therefore being viewed by many companies as essential time for further research, testing, validation, and commercial scaling. Developing a biodegradable coating in a laboratory is one challenge; demonstrating consistent performance across different crops, climates, substrates, and growing practices is another altogether.

Not all fertilizer producers are equally positioned to tackle this transition. Success will likely depend on substantial investment in research and development, as well as access to multidisciplinary expertise involving polymer chemistry, material science, agronomy, and process engineering. Companies with long-standing experience in controlled release technology may be better equipped to navigate these complexities, but even for them the outcome remains far from guaranteed.

At the same time, the industry’s commitment to finding a solution remains strong. Controlled release fertilizers continue to be widely regarded as one of the most efficient plant nutrition technologies available. By synchronizing nutrient availability with plant demand, they help reduce nutrient losses, limit leaching, improve fertilizer use efficiency, and reduce labor requirements through fewer applications. These benefits closely align with the sustainability objectives that European policymakers are aiming to promote.

For growers, the extension provides reassurance that manufacturers will have more time to refine new technologies before they reach the market. The ultimate goal remains unchanged: enabling professional growers to continue producing healthy, high-quality plants without sacrificing the reliability that has made controlled release fertilizers a cornerstone of modern horticulture.

Whether the industry’s researchers can fully bridge the gap between long-lasting nutrient release and complete biodegradability by 2028 remains one of the most important questions facing the sector. Today, there is still uncertainty. But compared with only a few years ago, there is perhaps greater confidence that the challenge, while formidable, may eventually prove solvable. The extra time does not eliminate the difficulty. It simply gives innovation a better chance to succeed.
