Emmanuel Ok in a study focusing on coastal non-saline ecosystems, highlighted the synergistic relationship between biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More and fertilizer in enhancing nitrogen use efficiency (NUE) and yield stability of soybeans. The research emphasized the benefits of biochar amendments in combination with nitrogen fertilizers for soybean growth, productivity, and nutrient dynamics.  

Coastal agricultural soils, often characterized by low organic matter and poor fertility, benefit significantly from biochar’s ability to improve soil structure, water retention, and nutrient availability. Biochar mitigates nitrogen losses through leachingLeaching is the process where nutrients are dissolved and carried away from the soil by water. This can lead to nutrient depletion and environmental pollution. Biochar can help reduce leaching by improving nutrient retention in the soil.   More and volatilization, creating a more sustainable nutrient environment for plant uptake. This results in significant improvements in NUE, leading to higher biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More accumulation and stable yields under varying climatic conditions.  

The integration of biochar with fertilizer reduces the overall dependence on synthetic nitrogen inputs, supporting more environmentally sustainable farming practices. The study underscores the potential of biochar-fertilizer synergy to optimize nitrogen utilization, reduce environmental impacts, and bolster soybean productivity in coastal non-saline regions. This approach offers a sustainable pathway to address agricultural challenges in marginal ecosystems.
