A closer look at viruses and viroids: Together for safer use of fertilizers from organic waste

Active

from 01/10/2025 until 01/12/2026

The project focuses on engaging the public in scientific research to improve the safety and sustainability of fertilizers made from organic waste. Its central aim is to understand and reduce the risks posed by plant viruses and viroids that may be present in compost and other organic fertilizers. By involving both home gardeners and professional growers, the project seeks to gather valuable information about real-world fertilization practices and promote safer, more sustainable approaches in agriculture.

 

At the outset, participants are invited to share details about the types and sources of organic fertilizers they use, as well as their methods of application, through online surveys. This data collection helps researchers build a comprehensive picture of current practices and identify potential risks associated with the use of organic fertilizers. Selected participants are then asked to provide samples of the fertilizers they use. To ensure proper handling, clear instructions and suitable packaging are provided for sample collection. These samples are analyzed in the laboratory to detect the presence of plant viruses and viroids. After the completion of the analyses, individual results will be provided to the sample donors, allowing them to learn about the findings related to their samples.

 

Beyond research activities, the project places a strong emphasis on education and public awareness. An online guide is developed to offer practical advice on the safe handling of infected plants and the responsible use of organic fertilizers. Educational materials, including articles in gardening magazines and social media posts, further inform the public about the importance of certified fertilizers and proper management of organic waste.

 

The findings and outcomes of the project are widely disseminated to the public, policymakers, and other stakeholders through various communication channels. This ensures that the knowledge gained supports evidence-based decision-making and encourages the adoption of sustainable agricultural practices. By connecting scientific research with everyday activities, the project builds a bridge between science and society, equipping participants with essential knowledge about scientific methods, plant health, and environmental protection. Ultimately, the project contributes to long-term sustainability and responsible management of natural resources.

Aim

The primary aim of this project is to improve the safety and sustainability of fertilizers produced from organic waste by actively involving the public in scientific research. The project seeks to identify and assess the risks associated with plant viruses and viroids that may be present in compost and organic fertilizers, and to promote practices that minimize these risks in everyday agricultural production.

 

By collecting data from home gardeners and professional growers about their fertilization practices, and by analyzing selected fertilizer samples for the presence of plant viruses and viroids, the project aims to generate new scientific knowledge that supports safer and more sustainable use of organic fertilizers. In addition, the project emphasizes education and public awareness, providing practical guidance for the safe handling of infected plants and responsible management of organic waste.

 

Through broad dissemination of results and recommendations, the project supports evidence-based decision-making among the public, policymakers, and other stakeholders, and encourages the adoption of sustainable agricultural practices. Ultimately, the project builds a bridge between science and society, empowering participants with knowledge about plant health, scientific methods, and environmental protection, and contributing to long-term sustainability in agriculture.

How to participate

People can get involved in the project in several ways. First, anyone interested can participate by completing an online survey about their use of organic fertilizers. The survey collects information on the types of fertilizers used, their sources (such as homemade compost or purchased products), and application practices. This allows both home gardeners and professional growers to contribute valuable data from their everyday experiences.

 

In the next phase, selected participants will be invited to provide samples of the fertilizers they use. Clear instructions and suitable packaging will be provided to ensure that sample collection is simple and safe. The collected samples will be analyzed in the laboratory for the presence of plant viruses and viroids. After the analyses are completed, individual results will be shared with the sample donors.

 

All information about participation—including the survey, instructions for sample submission, and updates—will be published on the project website. Participants are encouraged to follow the website for the latest news and guidance. By taking part, individuals help advance scientific knowledge, improve the safety of organic fertilizers, and promote sustainable agricultural practices.

Needed equipment

No specialized equipment is required to participate in the project for most participants. To complete the online survey, only access to a computer, tablet, or smartphone with an internet connection is needed.

For those who are invited to submit fertilizer samples, the project team will provide all necessary materials, including sample containers, packaging, and detailed instructions for safe and proper sample collection and labeling. Participants do not need to purchase or prepare any additional equipment themselves. All laboratory analyses will be conducted by the research team.
