Simultaneously applying inorganic and organic amendments can be a practical strategy for improving the physical, chemical, and biological properties of the soil and preserving crop productivity. This book compilation, which is currently available, is titled "Book presents a comprehensive analysis of how recommended fertilizer doses and the combined application of biogas slurry can improve problematic saline soil and improve wheat productivity." It highlights the benefits of biogas slurry for soil health and discusses how it can support sustainable agricultural practices by reducing the need for chemical fertilizers. These invaluable resources will be helpful to researchers, agronomists, and environmentalists who want to optimize the benefits of biogas slurry for improving soil properties and ecological sustainability.
