Fish waste (FW) contains large amounts of protein and is a challenging feedstock for biogas production due to possible H₂S and ammonia generation. Adding FeCl3 to an anaerobic digester can precipitate H₂S. Mackinawite and greigite are conductive and magnetic substances formed from H₂S precipitation. Direct interspecies electron transfer (DIET) can be stimulated by developing these conductive materials and by applying an external magnetic force. In this study, FW was digested in batch reactors and exposed to magnets magnetic fields from 3 to 115 mT. The results showed that the use of magnetic fields could increase the biomethane yield by up to 36 %. XRD analyses showed that mackinawite and greigite were accumulating in the solid phase in digesters added FeCl3. Genetic analysis of the microbial community suggested that applying a magnetic field not only increased the relative abundance of protein-hydrolyzing bacteria but also potentially improved methane production through DIET.

In Chapter 2, the authors focus on the importance of precision-based soil and nutrient management practices tested on rice farms in the eastern part of India and the potential for reducing GHG emissions. This is highly relevant for countries such as India, Vietnam, Myanmar, Bangladesh, and Thailand with large areas under rice production, where the use of excess amounts of fertilizer and chemicals, especially nitrogen fertilizer, is a serious problem for the environment and health of people. The chapter shows the importance and benefits from the use of tools ranging from the simple leaf colour chart to innovative digital tools and their relevance to improve nutrient use efficiency. The chapter towards the end provides guidelines/models and policy recommendations for upscaling precision soil and nutrient management in rice systems and other related food crops.
