In the quest for sustainable agriculture, a groundbreaking study from Cranfield University is paving the way for a greener future. Led by Ruben Sakrabani from the Faculty of Engineering and Applied Sciences, the research delves into the use of advanced imaging techniques to evaluate organo-mineral fertilisers (OMF), offering a glimpse into how technology can revolutionize the energy and agriculture sectors.
Fertilisers are the backbone of modern agriculture, ensuring that crops receive the necessary nutrients to thrive. However, the rising costs and environmental concerns associated with traditional fertilisers have sparked a search for sustainable alternatives. Enter organo-mineral fertilisers, which combine organic amendments with mineral nutrients, promising a more eco-friendly approach. But there’s a catch: the inherent variability in the composition of organic amendments makes standardization a challenge.
Sakrabani and his team have tackled this issue head-on, exploring the feasibility of using neutron computed tomography (NCT), X-ray computed tomography (XCT), and Raman spectroscopy (RS) to analyze the physical and chemical characteristics of OMF derived from anaerobic digestate and coupled with carbon capture technologies. “This is the first attempt to utilize a combination of imaging techniques to investigate OMF,” Sakrabani explains. “Our goal is to demonstrate the feasibility of these non-destructive techniques for measuring the variability between individual samples.”
The study, published in the journal ‘Frontiers in Sustainable Food Systems’ (translated from English as ‘Frontiers in Sustainable Food Systems’), represents a significant step forward in the field. By combining NCT and XCT, the researchers were able to generate detailed images of how uniformly packed each OMF pellet is. This level of precision is crucial for ensuring the consistent quality and effectiveness of these novel fertilisers.
However, the use of Raman spectroscopy to characterize OMF proved more challenging due to the high fluorescence background arising from its matrix. Sakrabani acknowledges the need for further development, stating, “We need to build on this work to enable image-based analysis using machine learning algorithms. This will allow us to determine the characteristics of large batches of OMF with confidence.”
The implications of this research extend beyond the agricultural sector, with potential benefits for the energy industry as well. The use of anaerobic digestate and carbon capture technologies in the production of OMF aligns with the growing trend towards circular economy principles, where waste materials are repurposed to create valuable products. This not only reduces environmental impact but also opens up new revenue streams for energy companies.
As the world grapples with the challenges of climate change and resource depletion, the development of sustainable fertilisers is more important than ever. Sakrabani’s research offers a promising solution, demonstrating the power of advanced imaging techniques to drive innovation in the field. By providing a detailed understanding of the physical and chemical characteristics of OMF, these techniques can help to ensure the consistent quality and effectiveness of these novel fertilisers, paving the way for a more sustainable future.
The study’s findings also highlight the potential for machine learning algorithms to play a crucial role in the analysis of OMF. By enabling image-based analysis, these algorithms can help to streamline the production process, reducing costs and improving efficiency. This could have significant implications for the energy sector, where the development of sustainable technologies is a key priority.
As the research continues to evolve, it is clear that the combination of advanced imaging techniques and machine learning algorithms holds great promise for the future of sustainable agriculture. By providing a detailed understanding of the physical and chemical characteristics of OMF, these technologies can help to ensure the consistent quality and effectiveness of these novel fertilisers, paving the way for a more sustainable future. The work of Sakrabani and his team is a testament to the power of innovation in driving progress towards a greener, more sustainable world.
